Browsing: Eyes Vision

Why Is Eye Health Important?

Having healthy eyes is important. Matter of fact, there are not very many out there that are lucky enough to have a 20/20 vision! Truth is, you will never know the condition of your eyes if you do not take yourself to the optometrist. It is important to have your eyes regularly checked to prevent avoidable damage, disease and other problems. Without consciously keeping your eyes healthy and taking care of them regularly it could result in a number of different diseases, weakness and even blindness.

Having Digital Retinal Imaging done every month can be great for you. Problems with eyes can develop without any warning. Sometimes there is no gradual progress and there are no symptoms. Having images of your eye and having them checked is a great way to make sure no permanent damage can occur. People sometimes do not notice a change in vision but diseases can actually be detected through images during an exam. Some diseases that can happen, that can be detected by retinal imaging are macular degeneration, glaucoma, retinal tears or detachments, diabetes, and even high blood pressure.

More problems that can happen most commonly are Blepharitis, Cataracts, Dry Eye Syndrome, Conjunctivitis and Glaucoma.

Blepharitis for example, is a bacterial disease that can affect the entire body. Hormones, bad nutrition, physical condition and things like stress can cause a person to have seborrheic blepharitis. If there is a build-up of the bacteria it can heighten to staph blepharitis. It can be compared to dandruff but it happens to the eyelids. It causes the eyelids to become flaky, scaly, greasy, and waxy because the eyes overly produce tears. This disease can cause small ulcers, baldness of eyelashes, scarring and red eyes. Hot packs on the eyes for 20 minutes after a thorough gentle cleaning can help. Also antibiotic drops and ointments are available upon need.

The digital scanning and imaging will show the state of your eye whether it is healthy or has some kind of problem. You will get a map of your eye which will give your doctor a chance to see your eye in a more detailed view to discuss with you what you have and catch something before it starts. He will show you the image and discuss everything with you for safety precautions, avoidance techniques and remedies to help keep your eye in good shape. There will be a permanent file that they keep with all of your retinal images to be able to catch anything forming in your eye by comparing the images from the past present and future.

A Lasik Procedure Could Help Remedy These 3 Common Eye Complications

If you're looking to undergo a LASIK procedure, your physician will have to carry out an assessment to determine whether you eyes are actually equipped for handling the surgery, the sort of treatment required and the range of laser ablation necessary (ie to reshape the cornea). For example, those who experience dry eyes will have to undertake preliminary treatment options before the LASIK surgical procedures can be carried out. On top of that, both your health history and the type of prescription drugs you use will also help ascertain when and if you may partake in LASIK surgical procedures.

After that, you may be asked to undergo a wave-front examination, which should help identify automatically any additional issues that could be curbing your vision. This particular procedure effectively scans one's own eye by simply developing light waves which are then refracted and concentrated by the light. In reality, an individual's eyes are supposedly to refract light completely across the retina's surface in order to develop the right image. Neverheless when a variance occurs, you may possibly suffer from at least one of several issues:

  1. Myopia or nearsightness – This condition is prevalent among just about 30% of people today. It is usually hereditary, which is primarily seen through childhood. Individuals can certainly view things in a close range but often suffer from clearly making out physical objects at a distance. Complications can at times get more severe with age. Some known side effects are headaches, pressure, plus fatigue-especially when driving a car or simply partaking in physical activity. If one determinates to pay for a LASIK procedure, a portion of corneal tissue will end up being eradicated to allow beams of light to able to focus on the retina more accurately.
  2. Hyperopia or farsightedness – Another twenty-five-percent of men and women suffer from farsightedness, which is the complete opposite of myopia. Once again, the following is a hereditary concern, yet can essentially be outgrown when children get older. Side effects are traditionally the same as nearsightedness as well. Much like myopia, in order to remedy this problem using LASIK medical procedures, your specialist will need to get rid of some corneal tissue. This again helps adjust the direction that beams of light enter into one's eyes.
  3. Astigmatism – This is the most typical problem people have; however, it can be simply fixed with reading glasses or contacts. Folks will definitely experience the same side effects. In addition, physical objects can come across distorted at almost any distance. Despite the fact that this is an inherited problem, numerous people may get astigmatism by over-straining the eyes and also having added strain applied by the eyelids onto the cornea. Those who get LASIK will be able to enhance their eyesight by restoring the cornea.

In conclusion, is a LASIK procedure something that is suitable for you? Regardless of the fact that countless people today are enjoying the benefits with this cutting-edge technology, it is preferred to check with your nearest eye specialist first. Make time to assess both the advantages and also disadvantages to observe if you are an ideal candidate for the procedure.

What Is Lutein and How Does It Help the Eyes?

If you're reading this, you're probably looking to give your eyes a little boost. Our eyes are the most important sensory organ we have. We perceive most of our world visibly – preserving that is very important, especially when we know our vision is getting worse.

However, for most people, it's easy to take their vision for granted. It's not until our (or someone who we care about's) vision is challenged that we start to really think about it.

Most believe that vision is a result of genetics and not much can be done to preserve or improve it. But fortunately we can. By consuming a good diet, plenty of exercise and sleep, we can all take incremental steps to preserve or improve our vision.

Many people do not realize that we need to regularly consume foods that help our eyes, including carotenoids. This is because the two major carotenoids in the eye, lutein and zeaxanthin, are not produced in the body. Rather, the body relies on a good diet, including dark green leafy vegetables like spinach, kale, and broccoli to obtain an adequate supply of lutein and zeaxanthin. They can also be found in corn and eggs as well.

Why are lutein and zeaxanthin important? As mentioned, these are two carotenoids mainly present in the eye. Lutein mainly exists in the retina (the lining along the back wall of the eye) while zeaxanthin (and some lutein) exist in the macula (which looks like a dot in the central area in the eye and is responsible for our central vision).

Furthermore, lutein is used to produce meso-zeaxanthin, which is used as a first line of defense against UV light for the macula. One of the major causes of vision loss as we age is exposure to UV light over time. The macula uses these carotenoids in the form of a target (ie bulls-eye) to protect itself from UV exposure.

At the center of the macula is meso-zeaxanthin. A little further away from the center (as in a bulls-eye) is zeaxanthin. Furthest from the center is lutein. Even though lutein is furthest away, its role in synthesizing meso-zeaxanthin, and its important role in protecting the retina make it important to have.

How much lutein and zeaxanthin should we consume? No official guidelines exist; however, studies show that noticeable improvement begins to occur when 10 mg lutein and 2 mg zeaxanthin are consumed on a daily basis. For patients with Advanced Macular Degeneration (AMD) or Cataracts, 10 mg or even 20 mg of both can help with treatment (always ask your physician first).

However, these are only guidelines. When it comes to these carotenoids, you can never have too much. There are no known side effects from consuming too much lutein or zeaxanthin – after all, they're both already present in the foods we eat. So to help your eyes, eat as many dark green vegetables, corn, and eggs as possible, and stay away from sugary foods with little nutritional value.

And even on our best days, it can be difficult to get more than 10 mg lutein or 2 mg zeaxanthin. Even though these quantities sound small, it's difficult to get enough of them in a typical diet on a daily basis.

That's why it's important to use a good multivitamin supplement containing high quantities of natural ingredients. The best ones can usually be purchased directly from a manufacturer and have a certificate of analysis (COA) showing that each batch produced has been tested to make sure it has the right amounts of minerals and nutrients.

Also, having an enteric coating is very important in a multivitamin. This protects the minerals and nutrients from being destroyed by the stomach acid, ensuring that most if not all nutrients are absorbed by the body into the bloodstream.

So in summary, make sure to get enough lutein and zeaxanthin on a daily basis through a good diet and by using a good multivitamin. By being proactive and making a few small changes now, you'll be on the road to great visual (and overall) health for many years to come.

Technical Steps to Frame Fitting

When selecting a frame, how do you ensure the frame fits properly? Do you use a technical guideline or rely on customer feedback? As the eyewear industry expands the boundaries of frame design, eyecare professionals need to adapt the characteristics of the frame fitting process to the changing climate of frame shapes and styles.

The technical steps to frame fitting is a guideline that will allow each user the ability to quickly identify a proper fit, while incorporating the needed fashion and function benefits a customer requires.

A technical fit will rely on five components:

1) Face shape;
2) Frame width;
3) Bridge style and size;
4) Temple length; and
5) Lifestyle.

Each of these components plays a vital role in helping choose the right frame for your customer.

The Five Components to a Technical Frame Fit:

1). Face Shape – Everyone has different face shapes, sizes, and features and this is why frame manufacturers produce many different types and styles of frames. The trick is to find a frame that uses the customer's features to benefit their fashion needs and overall appearance. Choosing a frame based on face shape is a subjective process because what may be considered appropriate based on facial shape may not be the look or style the customer wants to wear. Below is a chart that will help identify which style of frame should be considered when looking at the shape of the customer's face:

Oval face – Normal shape – Most shapes will be suitable

Oblong face – Long shape – Deep frame, preferably with a low temple

Round face – Wide shape – Relatively narrow frame, preferably with a high temple

Square face – Wide shape – Same criteria as a round face

Triangular face – Erect triangle shape – Width of frame should equal lower widest part of facial area

Diamond face – Inverted triangle shape – Lighter looking frame (metal or rimless)

2). Frame Width – A technical detail that matches the width of the frame to the customer's face. The frame front should be wide enough to allow for a generally straight path from the end of the frame to the ear. Frames that are too wide or too narrow can cause the customer discomfort, and can affect the structure of the frame, not allowing the frame to stay in adjustment. A simple way to determine if a frame is too wide, too narrow, or just right, is the position of the eye in the frame.

To Wide : If a frame is too wide for a person's face, the customer's eye position will be near the bridge of the frame. When this occurs, the customer will appear cross-eyed and there will be a significant amount of lens material towards the temple side of the frame. While this type of fit could work in products that are designed to provide an oversized appearance (ie sunwear), it is not recommended for clear lens designs.

To Narrow : If a frame is too narrow for a person's face, you will have two key indicators: the eye position will be towards the temple side of the lens, and the temples will be touching the side of the face well before the ear, producing a “squeezed” look on the face. When this occurs, it is best to identify the eye size of the frame and avoid other frames that are below that eye size.

Just Right: If the frame width is correct, the eye will be positioned in the center of the lens and will produce a direct path for the temple from the frame front to the ear. If the position of the eye is not exactly centered, you should have the eyes positioned slightly inward towards the bridge instead of outward towards the temple. In cases where a customer has a narrow pupillary distance (PD), look at the position of the eyes in the lens first and determine if an adjustment to the difficulties can reduce or relate any squeezing appearance that may be present.

3). Bridge Size and Style – Once you have determined a good width for the customer's face, you now need to be concerned with the bridge style and size. This section is critical because the bridge supports 90% of the frame and lens weight. So a good bridge fit will help produce an overall comfortable fit.

The primary factor that determinates a good bridge fit from a bad bridge fit is the amount of surface resting flush upon the nose. The more bridge surface resting on the nose, the more weight is distributed equally, the more comfortable the frame will feel. Conversely, if there is less distribution of weight on the nose, or the bridge sits on a less area, then the frame will feel uncomfortable and will create pain and irritation for the customer. While there are techniques and tricks that can alter and improve the fit of a bridge, there is no substitute for selecting a bridge that initially provides a good fit.

4). Temple Length – Now that we have a good understanding about how the frames rest upon our face, we need to start understanding how the frames hold themselves in place. The bridge may support 90% of the frames weight, but the temples will most likely require about 90% of the frames adjustments. Just like the bridge, temples that fit well are paramount when considering the overall comfort and fit of a frame. A well-chosen bridge will often fit a patient's nose with little or no adjustment, while a pair of temples will always require some type of custom adjustment to fit each customer individually.

Like the correct bridge fit, a correct temple fit relations on placing the maximum amount of temple surface over the greatest area. When you fit a frame, the temple weight should feel even displaced between the back of the ear and the front of the frame. When a frame becomes uncomfortable, generally it is caused by a concentration of all the holding power the temple has on a limited area.

Another key indicator of proper temple length is identifying where the bend of the temple takes place. A proper temple bend will begin immediately after the top base of the ear (this is where the ear and skull connect) and will contour to the skull.

If a temple length is too short, you will notice the bend of the temple begin prior to the base of the ear, placing maximum pressure on the backside of the ear. When a temple appears to be too short for the customer, it will always be best to select a different temple length (if available) or select a different frame altogether. Trying an adjustment to a temple that is too short will be time consuming and absolutely will leave the customer with an uncomfortable fit.

If a temple length is too long, you will notice the bend of the temple beginning after the base of the ear, so making the frame appear unstable and loose. When a temple is considered to be too long for the wearer, an adjustment may be performed to properly fit the temple to the wearer's skull. If you had to choose between a temple being too long or too short, it would always be better to have more frame material to work with than less.

5). Lifestyle – In determining what type, style, and shape frame a customer should be fit into, you should ask the customer how they intend to use their new frames. This information will allow you to direct the customer to select the appropriate frame type that allows them to use their product in a fashion that does not cause the product or potential the customer, harm. This can be achieved by asking questions to learn more about the customer and their hobbies, interests, and work. Again, we do not want to fit and extremely sell a product that can not meet the demands and abuse each individual place on their product. The more information you can receive from the customer about their intended use of the product, the better equipped you can be to help select a frame that is right for them.

Other Items to Consider when Frame Fitting:

While the five tips above will help you produce the best frame fit for your customer, there are other options to consider when completing the fitting process: a customer's prescription strength, lens types (progressive addition lenses, bifocals, single vision, etc.) lens materials, and facial measurements (segment heights, pupillary distances, etc.). Failing to consider these options when fitting a customer will produce a product that will not meet the performance needs to achieve visual satisfaction and the fashion demands of the customer.

By understanding and implementing these five technical fitting tips you will be able to help your customer's choose a frame that fits properly, and handles the demands of their lifestyle.

The Three Essentials to Effective Vision Correction Training

Vision correction training is a process that uses a combination of three different essentials synergistically to yield amazing results in the clarity of your eyesight. In this article, you will learn these three essentials in order to maximize your natural vision correction training program.

1. Do the Right Eye Exercises

There are many different types of eye exercises and this can lead to great confusion when you are trying to find the best eye exercise program for yourself. In fact, most people do not even know about eye exercises or vision correction training, so discussing details about it quickly leads to the back 40 for most people.

So, stick with me and I'll lift the fog. The most common types of eye exercises are convergence, relaxation, and accommodative insufficiency exercises.

When we talk about Convergence Exercises , were really talking about how your eyes work together to focus on an object. When you look in the distance, your eyes coordinate with each other to see the object in 3-D without any double images. If you notice the difference between looking in the distance and looking at, say, a book, you'll soon notice that your eyes converge when looking at the book. They must converge toward each other to keep the book at one focus point. Convergence exercises target the muscles outside your eyes called the extraocular muscles , which have nothing to do with your ability to focus clearly. If you have ever seen a demonstration of an “eye exercise” with two circles that develop a third circle in the middle if you look at it right, you have just completed a convergence exercise.

Relaxation exercises are important for people who have normal eyesight, but have not noticed that when they look up from reading or doing computer work, things in the distance are blurry but then clear up within a few seconds. This problem is caused by excessive near work and can lead over time to permanent nearsightedness. This is the stage in nearsighted development when people get the absolute best results with relaxation eye exercises because they target the ciliary body muscle inside your eye responsible for clear focus. It is this muscle that needs to relax, and by continuously doing exercises that relax the ciliary body muscle, you can prevent permanent nearsightedness.

Accommodative insufficiency is a big two-word phrase that simply means “can not focus”. Exercises for blurry distant or near vision simply target the part of your eye that is responsible for focusing at all distances. These exercises are for people who wear glasses or contacts to see clearly, but want to be able to see again without them. Very few eye exercise programs provide these exercises.

2. Use Effective Nutritional Intervention for the Eyes

The second essential to successful vision correction training is proper nutritional support – for the eyes . The correct combination of nutrients is easy to come by … most supplements for vision contains them. How they are absorbed in the body is another story, and this is where nutritional supplements diverge. Absorption becomes the single most critical factor between good and bad supplements. Absorption is critical because you may take a pill that contains 500mg of Lutein, but only 50mg of it is actually absorbed in your body. You only get the benefit of that 50mg. Most pills or tablets will provide about 10% absorption while an intravenous injection will give 100%. Biomax's Pure Focus is packed with the essentials for optimal eyesight and it is taken sublingually, meaning under the tongue. This provides a 95% absorption rate.

3. Integrate Eye Relaxation Techniques into Your Routine

Finally, the last essential to successful vision correction training is proper eye relaxation. Eye relaxation techniques are bundled and sold by other companies as “Eye Exercises”, even though they are not “exercises” for your eyes. This is confusing to most people because the human eye is designed to see clearly in the distance when it is at rest, but the idea of ​​an “exercise” is to do work. Over time, people who spend most of their day focusing on things on their desk can develop an internal stress in the focal system which can temporarily rob them of their distant vision. Eye relaxation can bring the focal system back to normal for those people, but it is also important to those who are working to improve their eyesight using accommodative insufficiency exercises.

Is Lutein for Macular Degeneration Effective for Prevention or Treatment?

The health of your eyes is not something to take for granted. Our visual senses are the primary way most of us sense the world around us. If you're completely nearsighted like me or suffer from any eye disease, you're probably reminded of this on a daily basis.

One particularly devastating eye disease is macular degeneration. It occurs usually with old age when loss of vision occurs in the center of the visual field because of damage to the retina. Basically, it destroys one's central vision, making it difficult to recognize faces and objects. Peripheral vision continues to operate, but can not compensate for a central vision that's already lost.

When it comes to macular degeneration, also called Age-related Macular Degeneration (AMD), there are two types: dry AMD and wet AMD.

Dry AMD occurs through the wasting away of the epithelial layer below the retina. Unfortunately, no medical treatments are available for this, but research shows that antioxidants, zeaxanthin, and lutein for macular degeneration to be highly effective for preventing and combating AMD.

Unlike dry AMD, wet AMD causes vision loss through abnormal blood vessel growth in the eye. Often, special prescription medications are effective to treat this ailment. Zeaxanthin and lutein for macular degeneration are also helpful here for prevention; however, specialized prescription medicine is required to effectively treat wet AMD.

However, both dry and wet AMD can be prevented by consuming plenty of zeaxanthin and lutein in your diet. Once you actually have the condition, however, it's good to take them in conjuction with treatment your physician provides (even, always consult a physician first in these cases).

Zeaxanthin and lutein are carotenoids – organic pigments naturally occurring plant pigments in chloroplasts and chromoplasts. Unlike plants, humans do not synthesize zeaxanthin and lutein alone – we must get them from our diet. Dark green leafy vegetables like spinach, kale, and broccoli are rich in both zeaxanthin and lutein. Corn and eggs are also contain them as well.

How does zeaxanthin and lutein for macular degeneration work? Well, think of the macula as a dot (ie a target or bull's-eye). The bull's-eye contains meso-zeaxanthin, which is created by the body from lutein. Going away from the bull's-eye you would next see zeaxanthin. Finally at the farthest periphery you would find lutein.

All three of these carotenoids (one created by the body, two we must provide for in our diets) play an important role in protecting the macula and our central vision. The lutein and macular degeneration link is very important because it not only provides for lutein, but also meso-zeaxanthin (created through lutein).

So it's crucial to have plenty of carotenoids in your diet. As noted before, it's important to eat plenty of dark green leafy foods which are rich with zeaxanthin and lutein.

Although there are no official guidelines, studies show that 10 mg lutein and 2 mg zeaxanthin on a daily basis can make a difference over time in improving eye health. However, these are only guidelines and no side effects have been associated with much higher amounts of these carotenoids. So consume as much of them as you can.

10 mg lutein and 2 mg of zeaxanthin may seem to be a small amount but in reality is not easy to get on a daily basis. It's important to also look for a good multivitamin supplement, especially when considering lutein for macular degeneration. Studies repeatedly show the link between lutein and macular degeneration, so make sure you're getting enough on a daily basis.

And when obtaining a multivitamin, make sure it's one of high quality. Too many people miss the potential benefits of multivitamins, especially when it comes to vision, because of poor quality and manufacturing processes. Look for multivitamins with good quality ingredients with high quantities.

Also it's best to purchase them directly from a manufacturer who can provide a certificate on analysis (COA) which demonstrates that the batch of vitamins you¡¯re consuming has been tested to ensure the proper quantities of nutrients are present in each tablet.

Finally, make sure that the multivitamin has an enteric coating so the important nutrients it provides are not destroyed by stomach acid and are instead fully absorbed into the blood stream.

By doing your research and looking out for these things, you not only help to ensure your overall health, but are making a great investment in your visual health as well. Keep these things in mind when looking for supplements – you'll find the results of preventing or treating AMD, better overall vision, and better overall health to be well worth the time, effort and investment in research.

Retinal Vein Occlusion Made Easy to Understand

Actually, it is the second most common vascular retinal disorder after diabetic retinopathy. Many of my friends were confusing vein occlusion with artery occlusion, but I always believe that if we understand something we will never confuse it with any similar thing.

You do not need to study anything to answer the following question in an ophthalmology exam “Discuss central retinal vein occlusion.”

Let's think together !!

First of all, any vein functions to carry blood away from the tissue it is draining (retina in this case). If the vein is occluded (information from the question you did not study) blood will not leave the retina leading to filling of blood vessels with blood, then they become tortuous and dilated. The increasing pressure on the wall of blood vessels will lead to retinal hemorrhages, edema which may reach the macula or the optic disc. That's the picture that you will see on fundus examination of a patient with retinal vein occlusion. In addition you may find cotton wool spots which indicate capillary occlusion.

This will lead to a gradual reduction in vision due to the direct effect on the retina with the haemorrhages, exudates and cotton wool spots.

I understood RVO but what caused it?

Something led to occlusion of the vein. This thing may be an internal cause like a thrombus that accumulated inside the lumen and occluded it. Predisposing factors for this thrombus include hypertension, diabetes mellitus and blood diseases (leukemia, polycythemia, sickle cell disease).

This thing may also be external like something pressing on the vein leading to its closure such as in cases of glaucoma and increased intraocular pressure or in cases of tumors pressing on the veins.

Management of retinal vein occlusion

It remains controversial though there are different approaches to treatment including:

Control of the cause which may be hypertensive or diabetes.Give the patient anti platelet drugs such as aspirin to prevent the enlargement of the thrombus.After relief of the haemorrhages try to detect ischemia (areas of low blood supply) using fluorescein angiography.

In ischemic cases and neovascular glaucoma, Laser photocoagulation or intravitreal injection of steroids and anti Vascular Endothelial growth factors (anti VEGFs) can be used to prevent neovascularisation and oedema. I hope it now clear and differentiated from the retinal artery occlusion (RAO) and other abnormalities in the fundus examination for the medical students and interested people from the general public. I hope that this article helped you.

Selecting Eyeglasses Not Only Means Selecting Frames That Suit Your Personality

There are many articles floating around on how to select frames according to your face structure or your skin tone, but very few people have written articles on how to select frames according to the weather condition. As a retailer I have come across many customers who complain that their frames have got decolorized or their color has flaked off with time and regret buying such frames.

Since many of us prefer to buy glasses online it is important that you make the correct decision before you purchase the glasses online. Here are a few facts of eyeglass frames that you should be aware of:

Metal Frames : Metal frames tend to get decolorized quickly, especially when they come in contact with sweat. Sweat is acidic in nature and hence corrodes the metal, which in return decolorizes the frame and the paint coating starts flaking off.

If you stay in a hot and humid place, plastic frames are highly recommended. Avoid using metal frames. If you feel more comfortable with metal frames, then you should choose gun metal or silver as frame colors. Avoid black, golden or any other color.

Plastic Frames: In general, plastic frames are considered to be the most durable. These frames do not lose their color and do not break easily. The only drawback is that these frames tend to lose their alignment- the frame gets wider as you use the glasses over a long period.

However, it is easy to re- align the frames. It is recommended that you take the glasses to a nearby optical store and they will be able to align the glasses for free or at a very nominal cost.

Titanium Frames: These frames have high malleability- they can be bent without breaking. Thus these frames need not be realigned for a long period. Moreover, these frames do not get decolorized. Although the titanium frames are more expensive than others, they are something worth investing as they last much longer than the others.

It is important that you select your eyeglasses that suit your personality. But it is equally important to keep in mind the above listed points if you are looking to buy glasses that last long and get value for money. There are many online sellers offering eyeglasses at very cheap price but you would not want your favorite pair to get discolored within few month of purchasing glasses. Do not hesitate to ask questions to the seller or the optician regarding frames as you are the one who is paying for the glasses.

Zeaxanthin for Macular Degeneration – Does It Help for Prevention or Treatment?

With more information increasingly available at our fingertips, it easier now more than ever to target common ailments and disease and treat them or prevent them before they could become a major problem.

Advanced Macular Degeneration (AMD) is one of those diseases. Prevention with AMD is key because once the macula – the part of the eye responsible for our central vision – is damaged there are few options to help restore vision.

Optometrists and ophthalmologists (eye surgeons) can diagnose and treat AMD with prescription drugs that can target AMD once it has shown its presence in the eye. Their advice should absolutely be followed.

However, there are a few natural nutrients that you can and should be taking on a regular basis. Lutein and zeaxanthin for macular degeneration are two essential carotenoids that are present within the eye. Carotenoids are found in nature as organic pigments – they are responsible for the vivid colors of fruits and vegetables.

Lutein and zeaxanthin are isomers – same chemically but structurally different. Lutein is concentrated in the retina which is the lining on the back wall of the eye. Zeaxanthin is present primarily at the macula (responsible for our central vision) which is at a point in the lower center portion of the eye.

The body does not produce lutein and zeaxanthin on its own so its important to obtain these from foods and supplements. Eating lots dark leafy foods, including kale, spinach, and broccoli is an excellent way to make sure you're getting lutein and zeaxanthin. You can also get both carotenoids from eggs and corn if vegetables are not your favorite type of food.

So you can see the benefits of lutein and zeaxanthin for macular degeneration. There's also beta carotene which is found in the same foods. Beta carotene has a variety of health benefits through the body.

For the eye, beta carotene is converted to an aldehyde form of Vitamin A called retinaldehyde. Retinaldehyde binds with a protein called opsin and this combined molecule resides in the photoreceptors within the retina of the eye. When light strikes the photoreceptor, retinaldehyde changes its form, and travels along the optic nerve to the brain. This is how we perceive vision.

So in addition to lutein and zeaxanthin for macular degeneration, it's important to get plenty of beta carotene as well. These three nutrients are key for maintaining good visual health and preventing diseases like AMD.

Preventative treatment is especially important with the eyes. Any eye disease such as AMD or cataracts can cause some damage to the eye which can be irreversible.

However, it's important to never give up hope. Nourishing your eyes (even with disease) with important and essential nutrients can have benefits. It's always important to talk with your physicist first to determine if taking these nutrients along with any treatment they provide you would be beneficial.

However, if your eyes are reliably healthy (disease free) and you're looking to keep them that way, do not be afraid to get as many carotenoids as possible. Beta carotene, lutein, and zeaxanthin are naturally occurring nutrients found in many fruits and vegetables– you can not go wrong by consuming plenty of them.

And it's important to not only get them from foods but supplements as well to make sure we're getting enough of these carotenoids on a daily basis. Although there are not any official guidelines, studies show benefits after taking 10 mg of lutein, 10 mg of beta carotene, and 2 mg of zeaxanthin on a daily basis. But taking more than these averages does not have any negative side effects. Always challenge yourself to get as much of these carotenoids as possible on a daily basis – it can make a big difference in your vision.

And be cautious when choosing any supplement since many sacrifice the quantity and quality of the ingredients to increase profitability. Manufacturing processes are also important. Obtaining a good quality multivitamin directly from a manufacturer that tests their products and provides a certificate of analysis (COA) is a great way as a customer to make sure you're getting the best quality supplements possible.

Also, it's always good to take some time to comparison shop to make sure you're getting the most value for the investment. With a little research upfront, you will find that the benefits of good quality supplements to be well worth the time and effort. For more information, click on over to the site below.

Improve Your Vision By Increasing Your Zeaxanthin and Lutein Dosage

If you've looked eyes health, you probably know about lutein and zeaxanthin. These are two carotenoids found in the eye – lutein is found primarily in the retina (the lining along the back wall of the eye). Carotenoids are organic pigments found in nature and occur naturally in chromoplasts and chloroplasts of plants and other photosynthetic organisms.

The macula resides in the rear, lower portion of the eye. It looks like a tiny dot, kind of like the period at the end of a sentence. Meso-zeaxanthin, zeaxanthin, and lutein all are present here and they all help protect it from harmful sun exposure. Sun (UV) exposure causes free radicals to form and over time this can lead to disease.

Neither of these carotenoids are produced by the human body – we must obtain a good zeaxanthin and lutein dosage from our diets in dark green, leafy foods like kale, spinach, broccoli, and corn. Meso-zeaxanthin is created by the body from lutein and is the first line before zeaxanthin and lutein for protecting the eye from UV exposure.

Advanced Macular Degeneration (AMD) and cataracts are both known to occur because the lack of these carotenoids over time along with sun exposure is very detrimental to the eye.

It has been shown that increasing our zeaxanthin and lutein dosages can make a big difference towards the prevention of disease and can improve the functioning of our eyes. Although there are not any official guidelines for daily zeaxanthin and lutein dosages, studies show improvement when at least 10 mg of lutein and 2 mg of zeaxanthin are taken on a daily basis.

However, these are only guidelines. Obtaining more than 10 mg of lutein and 2 mg of zeaxanthin will not have any adverse consequences since both are already found in nature and in the foods you eat. Ideally, you should get as much as possible of both carotenoids in your diet on a daily basis to help improve eye health.

As mentioned before, by following a good diet you can get good amounts of lutein and zeaxanthin. However, even though these amounts look relatively small, it often takes eating a large amount of these vegetables to obtain a good zeaxanthin and lutein dosage.

Can increasing lutein dosage help for other conditions? Some suggest that it is effective in fighting colon cancer and breast cancer; however, evidence for this is insufficient at best. It's best to think of lutein and zeaxanthin as nutrients that help to keep our vision at our best.

In addition to eating the proper foods, it's also important to include a good quality supplement to your daily regimen. The best supplements use all natural, high quality ingredients and are produced in quality controlled conditions. Ideally, it's best to purchase supplements directly from a manufacturer that can provide a certificate of analysis (COA) which shows that each batch produced has the right amount of minerals and nutrients in each tablet.

It's also important to look for an enteric coating. This is a special kind of coating that ensures that stomach acids do not break down the multivitamin – rather, the multivitamin is broken down and absorbed in the small intestine – to ensure the best absorption of the minerals and nutrients.

Keep these things in mind when getting your next multivitamin. By comparing the quality, quantity, and types of ingredients, you can easily determine which ones are best for your visual and overall health. And taking the small daily steps by providing your eyes with the right nourishment can make a significant difference over time, leading to better vision and lower chances of disease.
