Transition Lenses Never Looked So Good

“I like you; your eyes are full of language.” – Anne Sexton

The human eye is an astonishing organ that reacts to light and serves a multitude of purposes to support our safety and wellbeing. It is important to care for your eyes, not only to maintain clear images and sight, but to aid in other aspects of your body and its health and motion. Having healthy eyes speaks to those with what you interact day after day.

Because our eyes react to light, it is important to protect them from damaging UV radiation. Transmission lenses, known in the industry as photochromatic lenses, are a very popular option for those wearing eyeglasses. Designed to be worn all day both indoors and outdoors, they provide the convenience of not having to tote pair of glasses everywhere you go. Transition lenses are manufactured and sold by a number of companies under various brand names, and widely available to the public to fit an almost limitless array of frame styles and lens types.

Transition lenses are created by applying a liquid base containing photochromic molecules to a lens material. A scratch resistant coating is then applied to protect the photochromatic substance. When exposed to UV radiation, the photochromatic molecules are activated, causing the lenses to darken. They are designed to deliver noticeably crisper, sharper vision, even in the brightest glare. Cost is a deciding factor for many individuals when it comes time to purchase new glasses, but many prefer the convenience of transition lenses as it eliminates the back and forth changing from regular glasses to sunglasses multiple times a day.

Many individuals are unaware that the UV rays from the sun can also be a serious danger to our eyes and can damage our vision. Transitions provide 100% UV protection and help prevent UV ray exposure daily, all with the convenience of having only one pair of glasses that transition from regular to protective sunglasses in just a few seconds.

Most modern windshields and windows are already designed to block UV radiation. This inhibits regular transition lenses from darkening as there is very little available UV light to activate them. A special type of transition lens has been developed specifically for this situation and shown to enhance visibility and safety while driving. Other adaptations to the photochromatic process allow for glasses which are helpful for computer users who may spend a large amount of time watching at computer screens. The transitions darken enough to help you see your screen better and ease the pain of fatigue and eye strain after long hours.

A versatile option for almost anyone, transition lenses are available in all types and styles for both men and women, young or old. They are also available in all types of prescriptions and offer a fast transition from indoor to outdoor light and glare. Children's prescriptions are now available in transit lenses for the many days of outdoor activities their schedule provides. Transitions do not just look good, they have set a new standard of providing better visual quality, comfort, and eye protection than ever before.

If your eyes are full of language, purchase a pair of transition lenses to portrait a look and feel that not only you will notice and enjoy, but those with what you interact.

Top Tips to Choosing Men’s Glasses Frames

When it comes to choosing men's glasses frames you have to be very selective in your decision. You may see a pair you really like, but once you put them on and see your reflection in the mirror, you can not get them off quick enough.

The reason for this is that there are certain types of specs that suit different facial shapes, so the first step to choosing men's glasses frames, is to know your facial shape.

Those with a square face, such as David Beckham or Arnold Schwarzenegger, will always benefit from a round design in a thin frame. When you have this facial structure, you do not want a heavy frame, but rather a frame that will blend into your face.

Those with a rounder face, such as Gerard Butler and Jack Black, will suit any shaped men's glasses frames. The rounder face is one of the facial structures where you will not find yourself restricted when it comes to overall design of the specs.

Heart shaped facial structures similar to Johnny Depp or Jason Castro will always enjoy the look that rounder specs provide.

The most important consideration is to ensure that the men's glasses frames you choose are not obtrusive on your face. While thicker and darker frames are in fashion, they are not suitable for everyone, which is why you should try on some frames either in store or using virtual mirrors, to see which will best suit your facial shape and coloring.

Men's glasses frames come in a host of different color options and this can be exceptionally difficult when it comes to choice. There is one rule of thumb that you may want to follow. If you work in a corporate environment and spend most of your day in a suit and tie, then a thinner metal glasses frame may be the best choice for you. If you are more a casual dresser then you can choose just about any color and get away with it.

Many people prefer purchasing their specs online. The online opticians offer high quality specs at affordable prices, this enables you to purchase more than one pair for around the same price as you would pay for one pair on the high street. This means that if you work in a corporate environment, but love relaxing on weekends, you can choose two completely different designs to suit your personality.

Size is also important when making your decision. It's important not to choose a pair of men's glasses frames that take over your entire face, which is why it's so important that you imaging the specs on your face and the overall look they will provide.

See if you can find an online optician that offers a virtual mirror. This enables you to upload your photograph and try on different specs. You can then share your pic with friends and family to get their honest opinion before placing your order.

The material you choose for your specs is very important. For a lighter and comfortable option, you may want to go with plastic. Plastic is a very light and durable material. Although those in the corporate world will be better off with a metal frame. If you choose metal, try and go with a lightweight frame, reducing the amount of pressure on the bridge of your nose.

Remember that any specs you choose must be comfortable. If they are too big, you may find you get headaches. In many cases people will put the headaches down to eye strain, but in fact it is you constantly frowning as you try and keep the specs on your face.

The Convenience of Prescription Sunglasses

Prescription sunglasses can offer convenience to those who wear specs on a daily basis or those who have chosen contacts over specs. Thousands of people worldwide prefer contacts because they do not have to wear specs, enabling them to wear sunglasses.

What people do not realize is that those with contacts actually are more comfortable when wearing prescription sunglasses, especially while driving. Often contacts can become dry irritating the eyes and traditional sunglasses Do not offer the same comfort that you would get if you were to choose a pair made to your exact specifications.

The biggest advantage is that the glasses available come in a range of modern frames. What you see in the stores as traditional options are available with your exact requirements. This is highly advantageous for anyone who wants to remain fashionable and wants the convenience and practicality that these can provide.

Prescription sunglasses come in unlimited lens options, which is highly beneficial for those who prefer a lighter feel to their specs or they want a plastic non-scratch lens. The good news for those who wear specs through the day is that you are able to pop your regular specs in their case and pull out your sunglasses, ensuring your eyes are protected against the sun without having uncomfortable and heavy clip ons.

Clips ons used to be the solution for those who wore spectacles; they were heavy and uncomfortable, putting unnecessary pressure on the bridge of the nose, which results in headaches. Now those who wear specs can have prescription glasses made to their exact specifications and no one will be able to tell the difference.

Transition lenses are another option. These are lenses which are clear when inside and once you head outdoors; they change to protect you against the unwelcome glare of the sun. These lenses can be included to any glasses order for an additional amount and is preferred by some people.

The reason many people go for transition lenses is they are not aware of prescription sunglasses. Those who wear transition lenses often find them very frustrating, especially when it's bright indoors and the lenses change on their own, leaving the person wearing darkened specs indoors.

Prescription sunglasses are designed to protect your eyes. These glasses not only offer protection from the glare, but they offer UV protection as well. Many people do not realize that the sun's UV rays can be dangerous to your eyes.

While everyone understands the dangers of the sun when it comes to your skin, they do not know that excessive UV exposure can cause problems with the eye. This is called photokeratitis and includes red eyes, pain and a gritty feeling in the eye. This can be an exceptionally painful experience, but with the right option this can be avoided. Never thing your regular specs will protect your eyes, unless they have transition lenses.

What you will love to know is how affordable prescription sunglasses are. In most cases they are no more expensive than your other specs that you're wearing right now. The best option is to search online; there are many online opticians that offer high quality products at really affordable prices.

The online opticians are able to offer competitive prices due to the fact that they do not have heavy overheads. In fact, in some instances you may be able to purchase two or more pairs for the same price you would pay for one pair on the high street.

Remember if you do decide to order online, you will need your latest prescription from your optician. You will also want to ensure the company you choose is reputable and reliable and can offer you exceptional service and fast delivery.

The Facts About Age-Related Macular Degeneration

Located in the retina, macular degeneration affects the macula, which is responsible for your central, sharp vision. As the disease progresses, the ability to see things is clearly worsens. Many older patients develop this issue as part of the natural aging process of the body. However, some individuals are more prone to the disease, including Caucasians, females, fair-skinned and blue-eyed patients, smokers and those with a family history containing AMD.

Typically, AMD affects one eye more than the other. Onset occurs when drusen deposits form underneath the retina. This deposit formation is termed “dry” macular degeneration. In more severe cases, new but very thin blood vessels form to supply retina nutrients and oxygen to the areas of the eye drusen suffocates. Due to their weakness, these blood vessels will leak blood behind the retina, leading to a more visibly disabling form of the disease, termed “wet” macular degeneration. Approximately 10% of AMD patients have the “wet” form of the disease.

Researchers are trying to determine why some people are more susceptible to drusen deposit formation than others so treatments and preventative medicine can be developed. One possible solution may be the use of various injectable medicines. Ideally injected into the retina, eye care doctors are awaiting future treatments will slow AMD's progress.

In many cases, AMD patients have a useful vision and minimal impact on their eyesight. However, those with more progressed forms of the disease have a difficult time even reading the newspaper or looking at pictures. There are eye care doctors called low vision specialists that provide low vision exams which can suggest the utilization of various low vision devices. Patients who undergo low vision exams are more likely to have success in using their remaining vision. Often times, there are state and local organizations that assist blind and visually impaired patients.

Unfortunately, nothing can prevent age-related macular degeneration. Luckily, some things can slow down the disease's progress. AMD patients can:

  • Stop smoking
  • Wear sunglasses that filter both UVA and UVB light for proper protection outdoors
  • Eat a healthy diet that includes green leafy vegetables (spinach, broccoli, kale, collard greens, etc)
  • Take a daily multivitamin
  • Undergo an annual exam to assess their macular degeneration status

If you have moderate to severe AMD and your eye care doctor feels you may develop “wet” macular degeneration, he or she may recommend a specific AREDS2-formulated eye vitamin that contains lutein, zeazanthine and fish oil to help reduce further damage. Many times, people are unaware they have the disease due to the absence of visual symptoms. This is the chief reason why visiting your eye care doctor every year for an annual examination is of the utmost importance. By catching age-related macular degeneration in its early stages, people can practice better eye care practices and slowly slow progress.

Selecting a LASIK Eye Surgeon: Find the Right One for You

Handing your wellbeing and trust over to anyone can be difficult. This can be especially trying when searching for an experienced, reputable LASIK eye surgeon. For those hoping to undergo LASIK eye surgery in the near or distant future, here is a helpful checklist peppered with resources to help you along the way.

While laser vision correction surgeries are extremely safe, it is critical for patients research local eye surgeons in order to find one that best fits their LASIK needs. Most importantly, people should ensure their LASIK eye surgeon is board certified to perform procedures. To complete this essential step, consult official resources like Certification Matters, the ABPS (American Board of Physician Specialists) or the North Carolina Medical Board. This should always be step one in finding any doctor, surgeon or health specialist. While a corneal specialist certification is not required to perform LASIK surgery, it is another step in the right direction since LASIK eye surgery is surgery on the cornea.

After confirming your eye surgeon is board certified and has an active medical practitioner license, examine their communication style. Be sure to choose a doctor that communicates clearly and proactively with you. Before undergoing LASIK, make sure your doctor:

  • Answers all questions and takes your concerns seriously
  • Ensures your questions are answered before procedure day
  • Does not rush you during your consultation and comprehensive examination
  • Thoroughly reviews steps you will need to take before and after your procedure
  • Discusses any and all fees associated with your procedure beforehand

Another tip in selecting a quality eye surgeon is to learn about the equipment and level of technology used in vision correction procedures. If the doctor's office has invested in state-of-the-art, FDA-approved lasers like WaveLight technology, you can rest assured their first priority priority is patient safety. In addition, learn about the eye surgeons you research through review sites such as Angie's List, Google + and Yahoo and asking people you trust in your local area.

Finally, be sure your eye surgeon is honest and upfront regarding your procedure bill. Be wary of any discount offers that seem too good to be true, as many times these bait-and-switch traps include fine print, hidden fees and the use of substandard technology. Also, steer away from any LASIK office that is unwilling to discuss fees before any eye surgery, as this exhibits untrustworthiness.

While this is certainly not a comprehensive list, these selection tips can guide you in the right direction towards finding a LASIK eye surgeon that fits your individual needs.

How Your Glasses Or Contacts Are Causing You Headaches

Have you ever had headaches after getting a new eyeglass prescription?

Have you ever wondered why you get those headaches? That is what we will explore in this article and some options below surgery to improve your vision. In order to understand what happens, we will be operating with the understanding that the bones of the head are capable of moving, which has been discussed in another article. More details on that later. Also it is important to understand that with vision, the eyeball will elongate or shorten based on whether you are looking at an object far away or close to you. This is so that the light rays converge at the back of the eye which is necessary for clear vision. People who are near-sighted or far-sighted are unable to have their eyeball change shape enough to adapt and have the light rays converge at the back of the eye appropriately.

How does the eye ball change its shape?

Anatomically, the shape of the eye is changed unconsciously by muscles attached to the eyeball, the extraocular muscles. These are very coordinated contractions that take place to produce specific changes with the eye ball. If any of these muscles become strained or become dysfunctional, then the shape of the eye may become distorted and the light rays may not converge optimally on the back of the eye ball. In addition the sphenoid bone, which forms the back of the eye socket and serves as an attachment for most of the extraocular muscles, also rotates forward or backward to aid in the elongation or shortening of the eye ball. This may seem implausible, but living bone has pliability and adaptability. When the bone has to torque to adapt to problems with one eye or both, body wide changes may be produced instantly. Commonly a scoliotic pattern can be instantly produced in real time that will change simply by closing the eyes. Upon opening the eyes, the pattern will reappear. That is how one can tell if vision problems are the culprit. Therefore your vision strains can be causing strains and tension through your body including neck pain and back pain.

What About Your Glasses Or Contacts?

Your glasses or contacts may be too strong or too weak meaning light rays converge behind or in front of the back of the eyeball. This causes the extraocular muscles and the sphenoid to strain to adapt to where the light rays are converging. Even if you can see clearly with your prescription, it may be placing a lot of strain in the extraocular muscles and sphenoid bone to adapt to it. It is this strain that causes headaches when your vision is not clear and your prescription is off as well. Laser surgery of the eyes will cause the lights to converge on the back of the eye when it is in its strained state. Therefore, relaxing the strained muscles will not lead to clear vision because the eye has been altered anatomically. It will keep the eyes in a state of constant strain.

What can you do about it?

The simplest and cheapest option to improving your vision naturally is doing eye exercises. There are great resources and courses such as the Natural Clear Vision Course. In addition, a behavioral optometrist may do an intensive eye examination and determine customized exercises to help with what your vision problem may be. Lastly there are some osteopathic doctors trained to structurally treat the eye ball and determine a prescription that allows your eye muscles and sphenoid bone to stay as relaxed as possible.

Lose Those Glasses and Get LASIK

Advances in eyeglass lens technology have spared even those with reasonable visual shortcomings from wearing thick “coke bottle” glasses. However, even today's thinner glasses bring their own set of problems. They can fog up, and frames (if not lenses) break. A new prescription means buying new lenses. And nearly everyone who wears glasses has experienced that sinking feeling when they simply can not be found.

Contact lenses are an improvement for many people, but their drawbacks include a constant need to resupply, discomfort caused by allergies (forcing many to go back to eyeglasses), and higher risk for eye injury and infection.

LASIK eye surgery is a treatment option to correct myopia, long-sightedness, and astigmatism to give people another alternative to wearing eyeglasses or contact lenses.

LASIK Surgery Improves Eye Function

LASIK is a type of refractive laser surgery that reshapes the cornea, a clear membrane that rests on the eye's surface and improves the major functionality behind the eye's ability to focus. The cornea receives and bends light before sending it to the lens and retina, which forms and sends messages to the brain. By reshaping the cornea, LASIK can improve how it communicates with the lens and retina thus resulting in improved focus and vision.

Eyesight After LASIK

It's important to understand that successful LASIK surgery will improve your eyesight but not necessarily restore perfect vision. Some people may need to wear glasses for reading or driving after LASIK surgery. Still, more than 90% of LASIK patients recover vision between 20/20 and 20/40 and that is not half bad if you've depended on glasses since you were a child.

Few patients regret having LASIK surgery. Being able to wake up and see more clearly every day, and not having to grope for glasses, is very liberating. Similarly, people who wear contact lenses often need to wear readers as well. Contact lenses are also a constant expense, and there are days when they just will not sit well on the eye and wearers have to resort to glasses anyway. Even for those wearing contact lenses, being able to see without constant maintenance is a huge quality of life improvement.

Over 40 with Presbyopia? Consider LASIK for Monovision

If you're over age 40 and have a condition called presbyopia, you might already wear contact lenses that provide you with monovision. This strategy has the patient wear a lens for close-up vision in one eye and a distance lens in the other. Alternatively, reading glasses or readers may be needed at least some of the time. LASIK surgery can provide the same monovision without contact lenses and their associated issues. Some patients even find less dependence on readers as well.

Talk to Your Ophthalmologist About LASIK

You may be a candidate for LASIK if you have good general health and have no eye diseases. Here are some questions you should ask if you are considering LASIK surgery:

• Is my vision in an acceptable range for successful LASIK treatment?
• Am I at the best age for LASIK?
• Has my eyesight been stable enough that it will not continue to deteriorate after
LASIK?
• IF LASIK does not work as well as we hop, what else can we do?
• What are LASIK's side effects and risks?

Planning Of Improving Your Vision? Tips To Do It Without Glasses

Did you know that you can improve your eyesight without glasses or contact lenses? If you did not know, here are tips on how to go about it.

Eye exercises

There are a number of eye exercises that you can do and improve your eyesight naturally. One of the best exercises is palming. Here you need to close your eyes with your palm and block all light from entering the eyes.

Another great exercise is “sunning”. Here you need to take at least 10 minutes daily to “sun” the eyes. To sun the eyes you need to close your eyelid and expose the eyes to the gentle morning sun. For ideal results, you should swing your head from left to right.

Diet

The food that you eat is very important when it comes to improving your eyesight. To ensure that your eyesight improves through dieting, you should eat foods that are of benefit to your eye. Some of the most beneficial foods are those rich in Vitamin A.

These foods include: fruits and vegetables such as papaya, carrots, broccoli, mangoes, pumpkins, and spinach. Fish, eggs, liver, and daily products are also very beneficial.

You should also ensure that you take plenty of foods such as oranges, lemon, guava, tomatoes, and other vitamin C rich foods. Garlic, onion, Shallots, capers and other surfurous rich foods are also very beneficial to the eyes.

Supplements

Supplements are very beneficial to your eyes. The good side is that there are a number of supplements that you can take. The supplements that you should take are those containing minerals and vitamins.

Two of the best supplements that you should consider taking are: Bilberry and Taurine supplements. Bilberry improves blood circulation to the retina while taurine aids in generating tissues in the retina. Experts recommend that you should take at least 180 mg of Bilberry and 500 mg of Taurine every day.

Massage

Eye massage is very beneficial to the eyes. It has been shown that eye massage increases blood flow to the muscles, skin, and capillaries around the eyes. Eye massage has also been shown to be very beneficial in draining excess fluids in the eyes. Massage also aids in toning the eyes thus reducing eye sagging.

To massage the eyes you should ensure that you sit in a comfortable position and then slowly use your palms to massage your eyes. To ensure that you feel no pain when massaging the eyes, you should be gentle.

Basic Understanding of Different Ophthalmic Sutures

Ophthalmology- there is definitely a lot of people who would agree that this is among the most intricate aspects of medicine. Also, many would also say yes to the statement that performing surgical procedures in the eyes is quite tedious. After all, the eyes contain several tiny and complex portions.

Suffice to say, the paraphernalia being used in ophthalmic surgical procedures are relatively smaller compared to those being used in other forms of surgical processes. There are different kinds of ophthalmic sutures. Majority of these sutures possess unique features, in order to suit a certain ophthalmic surgical intervention, whereas the other kinds are interchangeable.

When it comes to ophthalmic sutures, those who prefer to pursue ophthalmology should be very familiar in various properties, like elasticity, tensile strength, absorb ability, propensity, handling, as well as tying characteristics.

Basically, ophthalmic materials, like ophthalmic sutures, are used in correcting different eye related conditions like:

• Squint
• Cataract Extraction or also referred to as Phaco
Glaucoma
• Retinal Detachment
• Corneal Graft
• Ptosis
• Lid Surgery
• Dacryocystorhinostomy
• Chalazion
• Evisceration / Enucleation

First and foremost, prior to conducting ophthalmic procedures, the experts have to pay utmost care and caution when choosing a certain method of introducing other items in the sterile field. As highly cognizable, sterility is considered as the most relevant aspect in surgical procedures, like ophthalmic procedures.

Other than the ophthalmic sutures, there are other materials that must be handled with extreme precaution, for instance, the sterile liquids. When pouring the sterile liquids, ideally, the bottle's edge should not touch the basin. It is because this particular part of the bottle is considered as non-sterile.

In any type of major eye surgery, the foremost thing that should be considered is the type of suture that should be utilized. The following items are most commonly used in many kinds of eye operation:

• Nylon

This ophthalmic suture material is also a form of synthetic material, and it is well-preferred because of its absolute strength, and it does not cause irritation to the tissues. Also, it does not support the growth of bacteria.

• Polypropylene

This is a torpedy yet strong ophthalmic suture material, which can not be weakened or degraded by the enzymes in the tissues. However, it is non-absorbable, and it could cause minimal inflammatory reaction.

• Mersilene

It is a form of polyester fiber suture, and it is typically being used in corneoscleral closure. It is less elastic but it is deemed to be stronger than the nylon suture material

Knowing the best supplier of ophthalmic sutures is the best especially if you are planning to undergo such a delicate type of operation. Your eye is the window of your soul, and it's important that this window remains clear and free from any type of impurities. Imagine using a substandard suture that will only give you problems such as eye irritations later on? This should never be the case.

Most eye clinics choose the products which are being offered by the Rumex Company. This business has been in this field for years, and they sure know how to provide awesome eye tools and services.

What You Should Know About Sunglasses And Prescription Sunglasses

There are three motivations to wear sunglasses. The first excuse for why is really self-evident! If you do not want bright sunlight in your eyes, the dark surface of the sunglass lenses shuts out bright light and makes the world darker (but not your mood!) The second, is for style – everyone wants to look great! The third, which is the most compelling reason, is that the sun's ultraviolet light can be destructive in the long haul, bringing on different kinds of issues with your eyes, including visual impairment (at worst, blindness) and melanoma, a form of cancer .

Ocular Melanoma is now one of the top causes of people losing an eye in Australia. That alone should be a good reason for us all to protect our eyes with good quality sunglasses, and your kids should wear them too!

Good sunglasses provide protection, as their lenses filter out most of the harmful UV rays. Good quality sunglasses provide UV400 protection from the sun's harmful rays. It pays to check what the UV rating is when buying sunglasses as there are ratings for UV protection (the higher the number, the better protection you will be giving your eyes).

So how do they work? The darkening effect is a very simple one: looking at the world through tinted lenses makes it seem darker to you – even thought the effect is really just an optical illusion, it can help you if exposure to bright sunlight tend to give you a headache or cause you to squint (less squinting also means less crow's feet around your eyes!)

The UV separation is more complex. UV filtering lenses are coated with special chemicals that allow light to pass through them, but reflect away UV. UV rays are basically high-frequency light waves, which means that the chemical structure has to be configured to deflect light while allowing through lower frequency light. This is tricky science, and the materials needed to do it are expensive.

The most complex sunglasses are prescription sunglasses with polarizing lenses. They do not just protect your eyes from light and UV, but also incorporate corrective lenses. These lenses combine the technology for ordinary corrective lenses to be tinted, laminated with a polarizing layer, and covered with UV reflecting materials. When all these facets are combined, glasses are transformed to sunglasses that not only cut out harmful UV rays, but also provide a more intense view of colors (due to polarization), and they correct your vision!

Natural Ways to Improve Your Vision Without Corrective Glasses

My Problem

As a long term wearer of glasses my condition is an extremely common one – myopia, or, near-sightedness. My vision is OK (but not perfect) when reading, but absolutely terrible for anything distance related. In an almost self defeating way I accepted that glasses were with me for life. I have dabled with contact lenses but I find them difficult to use and not at all comfortable after a few hours. They just do not work for me. Laser vision is another alternative, until I heard that it may not fix my eyesight long term, nor correct the astigmatism that I suffer. It's also expensive.

My Discovery

So, after reading about Dr WHBates, an ophthalmologist going back to the 1900s, I was intrigued to discover that during his career he did not encourage the wearing of glasses, or if he did prescribe them they were usually weaker than required. His basic philosophy was that the eye could be encouraged to see perfectly without glasses through the use of eye relaxation, and focussing techniques. His belief (proven by countless experiments) was that the muscles of the eye controlled focussing, not the lens, and there before it was possible to bring the eye back into clear vision. He reasoned that modern activities such as reading and writing was much more common now than in the days of early man where hunting involved long distance vision, and the evolution of the eyes to see afar were naturally “at rest” and in a relaxed state. Anything involving near point focussing required mental strain.

A Warning

Before I begin with the relaxation techniques it is important to understand that if you wear glasses to drive or work or basically anything that involves a degree of risk of injury to you or others, it is naturally common sense to wear them. Bringing your vision back to perfect is a long process and requires work, it is not a one day cure.

The Activities

The first activity involves the simple art of palming:

1. Sit at a table, or on the floor if you desire. Remove glasses.

2. Rub your hands together to generate heat.

3. Place your hands over your face so that the palms face over your eyes but not touching them.

4. Close your eyes and relax them completely.

5. Feel the heat of your palms dissolve in and around the eye area.

6. Do this for 30 seconds at a time, and repeat as necessary.

The second activity involves swinging of the eyes:

1. Stand up and remove your glasses.

2. Gently move your head left to right, and back again, in a slow swinging motion.

3. Your eyes will naturally try to focus on objects about the room as you move your head. Do not allow this to happen. Simply let your eyes relax and unfocus.

4. Do this for a few minutes. Your eyes should feel refreshed.

Finally, a focussing technique:

1. Search the internet for a “snellen card” – this is the famous test card containing letters that typically get smaller as you read down the card.

2. Print it out and paste about 6 meters (20 feet) from you.

3. Remove your glasses and simply cover each eye at a time and read the card, making an attempt to define the shape of each letter as you read along and down.

4. Read the card a few times daily, ideally in the morning.

These are just a few easy things you can do to help improve your vision. Practice them daily and you eyes will feel relaxed and begin to see clearer than ever.

Choosing the Right Lens Material – Getting the Best Eyeglass Value

We all want to look our best and our eyeglasses may be one of the best dual-purpose fashion accessories we wear! When it comes to eyeglasses two constants require our attention: Getting the best possible vision correction and, getting the best value for our money. If we choose the right lenses for the job then we're free to choose the best frame color, material, or shape that makes us look our best but, picking the right lens for our eyeglasses ties all the other shopping together.

The vision correction measured in our exam and shown in our prescription dictates the minimum choice in eyeglass lens materials. Each lens material has limits in how much it can correct our vision. These practical limitations are understood by your optician or optometrist. They can help you make the best choice between cost and appearance and getting the thinnest lens possible. Your goal, first and foremost should be the goal of obtaining an optimistic vision and that is accomplished by choosing the right lens for the job. If your Rx allows a choices in lens material the following table will help you choose the best lens material for your frames and help you accomplish the thinnest lenses and your best look, within your budget.

There are several types of plastic in use in eyeglass lenses today. They are listed (below) in the order of their thickness, with standard plastic resulting in the thickest lens profile compared to the others. Also shown is the “index value” for the lens material. The index value of a lens roughly equates to its thinness and can be used as a guide in choosing lenses. Your optician or optometrist will usually help you choose the right lenses but when there is more than one lens material capable of solving your prescription, it is best to choose the one that yields the best cost to benefit ratio for solving your Rx. It may make sense to spend more to get a thinner lens in your glasses if you have a higher power Rx. That said, some frames do better at concealing thick lenses than others so consider your frames as part of the lens solution. If you need your glasses for work or sport or avocation, then we suggest either Trivex or Polycarbonate lens material due largely to superior impact resistance.

As lens material gets thinner, the index value gets higher and, as the lens index value goes up the cost of the lens material goes up too. If you do not need the thinnest lens material to solve your Rx, choose a lens that looks good in your frame. Small differences in lens index value are strictly noticeable in most cases when you select the right frame. Buying a more affordable lens allows you to buy a better frame or buy an extra pair of glasses with your savings. The best advice is to buy the lens material that gives the best balance of cost and thinness that is capable of solving your Rx. Any qualified optician or Optometrist will have able to help you choose the right lense. You may also wish to consider ways to minimize lens thickness that can not be avoided due to your Rx requirements.

Here is a rundown on the lens index value, approximate reference cost and common material attributes.

Oculofacial Trauma

Injuries to the globe, eyelid, lacrimal system, and orbit should considered when dealing with facial trauma. Careful ocular and adnexal exams are necessary to diagnose hidden ocular injuries. Furthermore, it is easy to focus on an obvious or serious ocular injury and lose sight of concomitant injuries. Expect the unexpected.

To begin with, obtain a careful history. The nature of the injury, timing, associated injuries are documented as best as circumstances will allow. Is there loss of vision, pain, double vision, or trismus? Is there a retained foreign body within the globe, eyelid, or orbit? Prior ocular history is also important. Previous surgeries, injuries, medical problems such as glaucoma, refractive error, amblyopia use of glasses and contacts are documented. Life threatening injuries obviously take precedence over globe or orbit injuries.

Examination includes as thorough an eye exam as possible, including visual acuity, ocular motility, confrontational visual fields, intraocular pressure, color vision. Next, an overview of the ocular adnexa, slit lamp exam, dilated fundoscopic exam. Consider B-scan ultrasonography computed tomography (CT scan), and / or magnetic resonance imaging (MRI) to rule out foreign bodies, fractures, and neuro-ophthalmic injuries.

Eyelid injuries can involve retained organic or inorganic foreign bodies. Organic matter, such as vegetable matter should always be removed. Inorganic bodies, such as glass and bullet fragments are removed. Although typically inert and usually not function-impairing, inorganic foreign bodies can prevent future or immediate MRI scans due to their magnetic properties.

Eyelid injuries can include partial and full thickness lacerations. Do not disgard even remotely viable tissue during repair, as the eyelids heal well due to their rich blood supply. If eyelid tissue is lost, reconstruction with flaps, allografts, or skin grafts is necessary. Immediate protection of the globe is always the priority. Eyelid lacerations often involve the lacrimal apparatus, such as canalicular lacerations. Repair canalicular lacerations with silicone stents. Lacerations involving the medial cantal tendon are particularly challenging. One must reattach the posterior limb of the medial canthal tendon to the posterior lacrimal crest to restore anatomic position of the lower eyelid to the globe. Lateral canthal tendon repair is simpler to repair, but just as important to proper eyelid orientation. If lateral eyelid tissue is lost, a periosteal flap with a myocutaneous enhancement flap is necessary for repair.

Orbital injuries can vary and imaging is usually necessary. CT scan is the first line imaging modality due to speed, bony anatomy, potential of metallic foreign body. Obtain an MRI for more soft tissue detail, particularly if the optic nerve, chasm, tract and cavernous sinus are involved.

Orbital Injuries can result in subperiosteal hematomas, intra- or extraconal hematomas, wall and orbital buttress fractures, foreign bodies, and extra ocular muscle contusions, lacerations, and hematomas. Orbital hematomas can often be observed if stable and not causing an orbital compartment syndrome. Otherwise, they are immediately evacuated. Repair orbital wall fractures in one to two weeks if there is persistent diplopia due to extra ocular muscle involvement or enophthalmos. Perform urgent repair (within 24 hours) for pediatric patients with “green stick” trap-door fractures, or otherwise muscle entrapment in adults. Zygomaticomaxillary facial complex fractures with significant zygomatic displacement or trismus should also be repaired in one to two weeks. The reason for waiting is to allow bruising and swelling to subside and allow easier repair. Preoperative antibiotics and corticosteroids are typically given.

Management of retained orbital foreign bodies depends on several variables. If possible, remove organic foreign bodies, particularly vegetable matter. Otherwise, chronic bacterial and fungal infections may develop. Organic foreign bodies are notoriously difficult to detect on both CT and MRI, even with contrast dye. Explorative orbital surgery is necessary if a high suspicion for foreign body exists even with negative imaging.

Remove retained inorganic orbital foreign bodies if they indent the globe, interfere with extra ocular muscle function, or are causing a direct optic neuropathy. Otherwise, they may be observed. Copper and iron foreign bodies may produce a chemical orbital cellulitis, and their removal is weighed against possible surgical iatrogenic trauma.

Globe injuries can range from mild to severe. A thorough ocular exam at the slit lamp or hand light is key. Examine corneal epithelial defects with a Seidel test if one suspects a full-thickness laceration. A shallow anterior chamber with an irregular pupal suggests a corneal, scleral or globe perforation until proven otherwise. Explore conjunctival lacerations for scleral perforations. Intraocular foreign bodies may be detected on CT or MRI, as well as B-scan ultrasonography.Look for traumatic iritis and hyphema. Retinal tears and detachments as well as intraocular foreign body warranty retinal consultation as soon as possible.

Head trauma can cause damage anywhere along the visual pathway: optic nerves, chiasm, tracts, and radiations. Traumatic indirect or direct optic neuropathy is common with occulofacial trauma. Decreased visual acuity, color vision, and abnormal pupillary reflex increases speculation for neurological damage and rule out if possible.

In summary, oculofacial trauma can be found in a myriad of ways. It is important to keep an open mind when evaluating these patients and obtain the most expedient and thorough exam as possible.

Why Polycarbonate Is a Great Choice for Eyeglass Lenses

Polycarbonate is a thermoplastic polymer injected in 1953 simultaneously by Bayer AG and General Electric. GE was searching for a better wire coating but soon recognized it as a candidate for a large assortment of products where a clear, high impact resistant and stable product was needed. As with the development of CR39 plastic resins destined for military bombers, the need for a better plastic polymer for aircraft canopies and helmet visors was one of the reasons polycarbonate thermoplastic polymers were advanced and perfected through the 1950's and into the 1960's. Because polycarbonate material was optically clear, thermally stable and highly impact resistant, NASA used polycarbonate for the bubble helmets worn by astronauts in the early space programs. Further developments made it possible for polycarbonate to be used as shields and sun visors used in later helmets. Due in large part to the success of polycarbonate as a helmet visor (non-ophthalmic) safety glasses and defense shields used by policing agencies, manufacturers extended the uses of polycarbonate to include ophthalmic lenses used in eyeglasses.

Advance in the polycarbonate technology incidentally ruled in the use of poly as wind screens used in fighter jets, attack helicopters, and even the space shuttles. During the 1980's polycarbonate materials made their way into consumer goods and today the advances in the polycarbonate formulations make it the material of choice in the manufacture of CD, DVD's and Blue Ray disk media that archive and store photos, movies, and documents. The advances of polycarbonate formulations during the last ten years have been especially good for polycarbonate as an eyeglass lens material because manufacturers of optical storage media like CD's, DVD's and Blue Ray disks demanded clear and more scratch resistant materials for their products. These advances have helped polycarbonate be the material of choice for some of the best ophthalmic lenses made because of their optical clarity, superior impact resistance and thermal stability.

Poly, or PC, as it is often referred to, has an index refraction value of 1.58 and features natural UV protection from harmful UV-A and UB-B radiation. Poly is considered to be superior to plastic lenses for eyewear due largely to its impact resistance and in that it is similar to Trivex materials in strength. Where Trivex has better overall optical qualities, Poly has the advantage of providing lower cost with only a small compromise in optical clarity for most patients. Poly is the lens of choice for children's eyewear because it is light and impact resistant and these same features make it a great choice for sports / recreation spectacles and for safety applications too, at more than half the cost less than the Trivex lens materials. Because poly is a softer plastic and is softer than CR39 plastic, it should be coated with an anti-scratch coating to minimize the impact of abrasion and it is usually suggested to also include an anti-reflective coating to minimize the presence of any chromic aberrations and reflected light back to the wearer's eye.

Polycarbonate lens materials have been consistently improved since they were introduced as a lens material in the 1980's. Poly lenses from five years ago are inferior to the poly lens materials of today largely because improvements demanded by the music and movie industries resolved in a better material for CD / DVD's that are used in producing music and movie CD's, DVD's and Blue Ray disks. As these improvements are incorporated into eyeglass lenses materials poly stands to grow as a material of choice for its overall capabilities as an eyeglass lens. These days, poly is an excellent lens material free of the many negatives attributes added to the finished product by the manufacturing process of yesteryear and today the polycarbonate lens is a great overall choice for its light weight, clear optics, UV resistance, impact resistance, and relatively low cost compared to Trivex and other high index plastic lens materials.

Poly is perfect for childrens lens products, safety applications, and even drill mount lenses. Cutting poly during the lens shaping process generates a noticeable stink but its blend of low cost, good refractive index and other optical attributes makes it a great choice for many eyeglass prescriptions and especially those for children, workplace uses, sport or other avocation or anywhere impact resistance is required for eye safety of the wearer.

5 Tips for Healthy Eyes

Those of us with healthy eyes and good sight normally take our eye health for granted. However, to ensure that our eyes stay healthy and strong into our old age it is important to look after them. There are several steps you can take to help make sure that your eyes can be as healthy as possible starting from today. Read on for 5 great tips in helping to keep your eyes healthy.

Vitamins

Eyes need nutrients to keep healthy, and nutrients which are rich in omega-3 fatty acids, zinc, lutein, and vitamins C and E are great for eye health. Regularly eating foods which are rich in these nutrients will help ward off age-related vision problems such as cataracts and macular degeneration. Foods rich in these nutrients include oily fish such as salmon and tuna, leafy vegetables such as kale and spinach, non-meat proteins such as eggs, beans and nuts, and citrus fruits and juices.

Healthy lifestyle

A healthy lifestyle which includes a good diet and exercise is a must for your body, and includes the health of your eyes. Make sure to watch how much alcohol you intake and if you smoke, try to quit. Smoking increases your chances of developing cataracts, macular degeneration and optic never damage.

Protect the eyes

Shielding your eyes from damaging substances and the sun should be a part of your everyday living. Always wear safety goggles when working with chemicals or machinery, and always wear good quality sunglasses which block out a high percentage of UVA and UVB rays. Wear protective goggles when swimming and wear eye protection when playing certain sports such as ice hockey.

Cut down on screen time

Cutting down on screen time includes watching television as well as looking at a computer screen. These activities can result in eyestrain and dry eyes. It could also affect your long distance vision. Another side affect of too much screen time is headaches and body aches and pains such as neck and back pain. By cutting down on your screen time you will not only help aid the health of your eyes, but also the health of your entire body.

Visit an Optician

If you notice that your vision is not as good as it once was, such as not being able to see things far away, or not being able to read well, then it is time to visit an optometrist. An optometrist will conduct an eye exam using charts and colors to test how your vision is. If short or long sight vision is affected the optometrist can order for you a pair of spectacles or contact lenses based on your eye examination, so that you can see clearly again.

Visit an Optometrist

Visiting an eye doctor for an eye exam can help keep your eyes in good health. If you notice that your eye is infected or has other issues such as cataracts developing then visiting an optometrist as soon as possible as this can help resolve the problem early and have your eyes back in good health again.
