A Look at Dry Eye

It may come as a surprise, but dry eye is one of the most commonly experienced conditions that people suffer from. Dry eye occurs when a person's eyes fail to produce the sufficient amount of tears that are required to lubricate and protect them. In some cases, the tear ducts fail to work alike, which results in itchy eyes that burn and vision that is hindered by blurriness. There are a few different causes of the condition, which is why it can affect anyone regardless of age.

Is Dry Eye a Dangerous Condition?

Although not life-threatening, it can cause sever discomfort. If left untreated, it will typically lead to more severe vision problems. General deterioration of the front surface of the eye is one possible exit, which is why tears are more important than most people think. If you have chronic dry eye, there are a few ways you can give your eyes the lubrication they need to function properly.

Dry Eye 101

Here is some helpful information for diagnosing the condition, as well as tips on how to effectively address the problem:

  • When tear production is hindered (due to an environmental or medical condition) the eyes are not lubricated and left vulnerable.
  • Dry eye is a natural condition that tends to affect people more as you age. As you get older, your body gradually decrees tear production.
  • Many medications and conditions such as arthritis and diabetes can cause dry eyes, as can prolonged exposure to smoke and wind. A failure to blink enough during the day can also aggravate the problem.
  • Optometrists recommend a few different treatment programs for patients suffering from dry eyes. Most often, tear additives such as eye drops will be prescribed. With regular doses, the solution will supplement the patient's existing tear production.
  • Eye doctors can also insert small silicone plugs into certain tear ducts as a means of conservation. This will minimize tears, strengthening the natural lubrication process.
  • Tear production can also be added naturally through a diet plan or prescription medication.
  • An easy prevention tip is to blink regularly, especially if you stare at a screen for a prolonged period of time.
  • Wear eyewear when outside to reduce environmental exposure. Wind and UV rays are harmful to eyes, so investing in a pair of quality sunglasses is worthwhile.
  • Stay hydrated; drinking plenty of water will help your body produce quality tears.

Be sure to contact an eye doctor if you notice a sudden decrease in the quality of your vision. The source of your dry eyes could potentially be more serious, and only a trained optometrist will be able to tell.

Protecting Your Skin Both In and Out of the Spa

In recent decades, the idea of ​​what constitutes a “spa” has undergone a transformation as has the idea of ​​what constitutes the “spa experience.” It is now possible to find treatments and experiences that are labeled as a “spa experience” in virtually every city and neighborhood.

Whether its on the other side of the world or down the street at the mall, the key idea behind any spa destination should be relaxation. A spa experience should be one where spa visitors are given services that lead to renewal and relaxation. Modern spas can seek to offer these calming and transformative experiences in a range of ways and may even include the incorporation of people's interests. For example, modern spas offer everything from meditation and yoga to climbing, hikes, fitness and nutrition instruction and more. The modern definition of the spa has evolved and grown to include personal development and growth as well as relaxation and fun.

Often spas will give treatments designed to rejuvenate skin and information about how to protect skin. Since wrinkles usually appear first around the eye area, a good deal of attention is often given by spas to helping revitalize and protect the areas around the eyes.

Outside of the spa, there is a great deal that you can do to protect both your vision and your youthful looks. The right lenses for glasses are vitally important for your health. The reason is that the optimal lenses will afford you valuable protection from UV rays. Exposure to UV rays can damage eyesight. Yet, opting for high end lenses for glasses such as those manufactured by Oakley, Prada, Arnette and others will give you the kind of protection that your eyes need. Polarized lenses can further serve to enhance your vision. What are polarized sunglasses? They work remarkably well at filtering out harsh light and the end result is enhanced clarity and then enhanced vision.

Another way to protect the skin around your eyes and your vision at the same time is to select the right kind of sunglasses frames. Wayfarer and cat-eye style sunglasses are savvy options, as they protect a larger amount of the area around the eye. These types of frames work extremely well with polarized lenses.

Investing in the right sunglasses can be just as important as a trip to the spa. High-quality sunglasses, such as Oakley or Arnette sunglasses, can help protect both one's vision and one's skin. Another key way to protect one's eyewear investment is to choose sunglass lenses replacements when lenses for glasses becomes damaged, scratched or chipped. Opting for sunglass lenses replacement is a prudent way to save both time and money.

The Basics of Diabetic Eye Problems

If you have diabetes, regular eye exams are necessary and essential. Why is that so? It's because high blood sugar (glucose) increases the risk of diabetic eye problems. In fact, diabetes is one of the major causes of blindness in adults aged between 20 and 74. Regular eye examinations will be needed to detect and treat eye problems.

Diabetic eye disease is considered as a serious problem that can lead to loss of sight. It may be developing even when your sight is in good condition that is why regular dilated eye exams are highly emphasized for finding problems early. Fortunately, there are several key interventions available to prevent such serious eye problems. One intervention is keeping blood glucose level closer to normal-this can prevent or delay the onset of diabetic eye disease.

Some people may observe visual changes such as blurred vision, seeing rings around lights, dark spots, or flashing lights. This is an indication of a pending eye problem. If you are experiencing any of these, be sure to tell your health care team or eye doctor about this immediately.

Symptoms

Most diabetic eye problems produce the following symptoms in general:

• Blurry vision

• Light flashes

• Gaps or holes in vision

• Appearance of black spots in vision

• Eye pain

• Headache

• Watery eyes

• Light sensitivity

These symptoms are the warning signs that call for vigilance on your part as a diabetic. If you are responsive, rapid diagnosis can be done and you can be saved from half the risk for eye diseases.

Protecting Your Sight

  1. Keep your blood glucose under control. High blood glucose can cause damage to your eyes if left uncontrolled. Work with your health care team to normalize your blood sugar levels in the target range. Check it regularly and stick to your daily recommended regimen such as taking in medications, healthy diet and exercise.
  2. Get regular eye exams. If you are diabetic and you are seeing fine, you will still need regular, complete dilated eye exams to protect your sight. Consult your doctor about it.
  3. Make sure to keep your cholesterol levels in check. High lipids in blood can heighten the risk of diabetic eye diseases.
  4. Regularly check your blood pressure and make sure it is normal. High blood pressure or hypertension speeds up the risk of getting eye diseases in diabetic patients.
  5. Follow regular eye care measures. Here are some tips on general eye care:

  • Perform simple eye exercises. Close your eyes and relax the surrounding muscles. Think of something that makes you happy. After 8 to 10 minutes, gently open your eyes and look entirely in to the distance. Next, try to look at something at an arm's length. If you do these eye exercises several times during the day, it will make the blood vessels and other features within the eyes strong and less prone to injury from diabetes.
  • To have a pair of healthy eyes even with diabetes, take diet high in vitamin A and low in carbohydrates.
  • In the morning, splash cold water into the eyes.

Eye care is something that you must give high importance to if you are diabetic. Reduce the risk of diabetic eye problems by being aware of signs and symptoms as well as following ways to protect your eyes.

Spotlight on Astigmatism

Astigmatism is a common eye condition that affects millions of people. Although not inherently life-threatening, it can put sufferers at risk due to theability of their eyes to adequately reflect incoming light. This occurs when a person's eye shape is incorrect, which is almost always caused by genetics.

The human eye is usually shaped like a sphere. When light comes into contact with the retina, it is reflected out at an angle. This allows us to see clearly without any obstructions. A person that has astigmatism will have vision that is blurred or distorted due to theability of their eyes to refract light. Incorrect eye size causes the refraction process go haywire as incoming light is scattered in multiple directions and angles, making it difficult for the patient to see clearly.

Why is Astigmatism such a Problem?

In most cases, a person who has astigmatism will be unable to focus their vision on multiple sources. Peripheral vision is the following hindered, causing a definite safety hazard.

Astigmatism 101

Here is some helpful information for diagnosing, treating and preventing astigmatism:

  • Common symptoms of astigmatism include blurred vision, fatigue and eye strain. If the condition is serious, these problems will be present at all times, not just when vision is being focused.
  • An eye exam is the easiest way to tell if the condition is present. An eye doctor will be able to tell right away whatever the eye size is correct. They will also check to see if other problems may exist.
  • Corrective lenses are often prescribed for treatment purposes. Glasses or contacts work equally well, but the final determination will be left to your eye doctor.
  • Refractive surgery involves altering the shape of the cornea to correct the refraction error, but this is typically required in the most serious cases.
  • Wearing protective eyewear and reducing eye strain can help ease the symptoms associated with astigmatism. Eating healthy is also essential for overall eye care.

If you think you may have astigmatism, be sure to contact an optometrist as soon as possible. The good thing about this eye problem is that is almost always corrected when the patient wears prescription eyewear. Glasses or contacts will work to concentrate the incoming light and solve the refraction error. In some cases, prescription lenses may not be needed to fix astigmatism, as long as the issue is addressed immediately. However, when the condition is serious, an optometrist will recommend refractive surgery to fix the patient's eye size.

Lasik Helps You See and Feel Better

I have suffered from poor vision my entire life. When I was in second grade I got glasses. Being the first kid in your class with glasses makes you the target of a lot of ridicule. Being called four-eyes is no fun. Either is having to make decisions like you should go swimming with glasses on and risk losing them, wearing ugly goggles to protect them, or diving in and not being able to see. I got contact lenses in high school. They provided their own obstacles. I would lose them, fail to keep them clean, and they were expensive. The minute I first heard about Lasik I knew I needed to learn more.

An eye doctor who using lasers reshapes the eye's cornea performs Lasik surgery. This provides improved vision and therefore eliminates the need for contacts or glasses. While the procedure seems like it is new, the patent was granted in 1989, and it has been popular since the mid or late 90's when it became a reliable technology that many people opted to try.

The day of my surgery I was really nervous. It certainly was not because I was going to miss wearing glasses. However, I've never loved seeing doctors, and knowing that I was undergoing a procedure on my eyes gave me a queasy feeling. I was even more on edge when I read the forms that they make you sign which indicate the absolute worst possible scenario of the surgery not go well. That being said my doctor assured me that he had done this hundreds of times and that the next surgery went wrong would be his first.

I knew that he was probably right because I had read a study by The American Society of Cataract and Refractive Surgery that found that more than 90 percent of patients were satisfied with Lasik. What I found even more amazing was the high percentage that never needed to use glasses again. This is so amazing because as people age generally their vision declines. To be able to have surgery done while you are young and healthy and reap the rewards of the procedure 50 years later is incredible.

My only complaint about Lasik is that my eyes sometimes felt dry in the months immediately after the surgery. A couple of my colleagues who have had the procedure noticed the same thing. While dry eyes are no fun, the condition went away after a few months, and I happily would have dealt with it on a regular basis if it meant no more glasses or contacts.

For some people contact lenses are just a part of their day. Others do not mind the way glasses look and feel. For me I did not like wearing something on my face and in front of my eyes from the day it was determined my vision needed assistance. After years of complaining and suffering Lasik was a great solution for me.

The Dangers of the Wrong Prescription

Your vision is a carefully calibrated sense, but if you do not have the right prescription, you could be setting yourself up for trouble. Your vision should be clear and sharp to ensure that you are able to perform at your best through the day. Here are a few of the dangers of a wrong prescription and how to fix it.

General Discomfort

The most noticeable symptom of a wrong prescription is a lot of general discomfort, especially when it comes to your eyes. You may find yourself training or squinting to see things properly, or you may start getting headaches or pain in your shoulders and neck from cringing your head to see clearly.

More Serious Issues

The more serious issues that a wrong prescription will create can negatively affect your health. Trying to see through a wrong prescription can make many people feel dizzy or even cause complete debilitation. This unsteadiness can make people feel nauseated and vomit. It can also give a person a sense of vertigo, especially in higher places.

Safety

Depending on how badly your vision prescription is off, you could actually be risking your safety and the safety of others. If you find that you are no longer able to see road signs as well as you normally should or that you are able to properly judge the distance between yourself and other cars, your prescription is probably to blame. Do not drive or perform any other hazardous activities if you believe your prescription is wrong-it is simply not worth the risk.

How to Know It's Wrong

Sometimes, it can be very difficult to know that your glasses prescription is no longer correct. If the difference between what would be correct and your current glasses is minimal, you may not even be able to tell. Things may be a little blurry, or you may have trouble seeing things you used to be able to see clearly. If your prescription is seriously off, you may notice increased headaches, eye strain, dizziness, and even feelings of nausea and vertigo.

Fixing It

If you believe your glasses prescription is not accurate or that you might need glasses, make an appointment with an optometrist right away. They will be able to give you the proper diagnosis you need, which will allow you to get the eyeglasses that are right for correcting your vision. If you're unsure whether your prescription is right, ask yourself when your last eye exam was. If it was more than a year ago or you can not remember it, schedule an appointment with your eye doctor. Remember, for the most accurate prescription you should have your eyes checked once a year!

Diabetic Eye Disease: What Is It All About?

Diabetic eye disease is referred to as a disease of the small blood vessels of the retina of the eye in people with diabetes. It is a term that covers a range of eye problems that when left untreated can cause loss of vision and even blindness.

Diabetes Mellitus

In order to understand the eye problems borne by diabetes, an understanding of the root of its cause is a must. Diabetes mellitus is considered as one of the leading causes of irreversible blindness in the world. In the United States alone, it is the most common cause of blindness in people whose age is below 65 years old.

Diabetes is a disease in which your blood glucose, or sugar, levels are elevated. You get glucose from the foods you eat. The hormone insulin is the one that helps glucose get into your cells to provide them energy. However, people with diabetes do not make insulin or do not produce or use insulin well. A lack of insulin in the body can cause the glucose to stay in the blood causing serious problems including blurring of the vision and sever permanent loss of vision. Diabetes mellitus also increases the risk of developing cataracts and glaucoma.

Diabetic Eye Disease

Severe diabetic eye disease most frequently develops in people who have diabetes mellitus for many years already and who have little or poor management of their blood sugars over that amount of time. But there are some that may not even realize they have had diabetes mellitus for several years until they start to come across problems with their eyes or vision.

Causes

Because of high blood sugar and other abnormalities in metabolism, diabetes mellitus may cause damage to the blood vessels in the body. This damage leads to poor circulation of the blood to different parts of the body. And as you know, the role of the blood is to transport oxygen and other nutrients. But if there is poor circulation, the oxygen delivered to tissues in various parts of the body is decreased causing for those tissues to be damaged later on.

The Retina

The retina is the major part of the eye affected by diabetes mellitus. It is the light-sensitive tissue found at the back of the eye and plays an important role of letting you see clearly. If it is swollen, wrinkled or otherwise anatomically impaired, the vision in that eye will be hazy or blurry. The alteration in vision will vary from marginal to sever and can be temporary or permanent depending on the type, location, and extent of damage in the retina.

The most common problem is diabetic retinopathy, a leading cause of blindness among American adults. Diabetic retinopathy usually affects both eyes. More often than not, people who have diabetic retinopathy do not observe changes in their vision during the early stages of the disease. But as it progresses, diabetic retinopathy usually causes vision loss that in many cases can not be reversed anymore.

Other eye problems include cataract which is a cloud over the lens of the eye and glaucoma which occurs when pressure is formed in the eye causing damage in the main nerve.

Preventing Eye Problems With Diabetes

If you have diabetes, annual eye exams must be done as this is particularly important. It can help determine a problem early on when it is more easily treated. It can also prevent further complications such as vision loss. Control of blood sugar and blood pressure are also equally important in preventing eye problems if you have diabetes.

Foods for Eyesight – Nutritional Strategies for Aging Eyes

When it comes to aging eyes, the common belief that prevails is that the ravaging effects of aging such as poor eyesight, age related vision disorders like Macular Degeneration, Cataracts and Night blindness are inevitable. Some individuals believe that people have to live with these disturbing vision conditions. However, in a modern world of scientific advancement and nutritional breakthroughs in eye health, this pessimistic point of view is simply unacceptable. This is due to the fact that you can take preventative steps in terms of nutrition to ensure that the negative effects of aging on the eyes is significantly reduced or even prevented; thereby still maintaining a high quality of life. Therefore, here are some foods for aging eyes:

There is a direct connection between the food that you eat and the quality of your eyesight. In this light, choosing the right foods for aging eyes is essential.The American Optometric Association's, dietary guidelines suggest that you should avoid a diet with a high content of saturated fat and sugar. This is because foods that are high in sugar and fat contribute to the development of eye diseases.
As a nutritional safeguard against age related conditions such as Macular Degeneration, Diabetes and Cataracts, eat a diet that supplies the body with an amount of vitamins, minerals, healthy proteins, Omega 3 Fatty Acids and Lutein.

The American Heart Association's recommendation is that you include 5-9 servings of fruits and vegetables in your diet on a daily basis. Often, this is a nutritional challenge for a lot of people because circumstances do not always permit the time to satisfy the nutritional needs the daily recommended allowance requires for maximum health. To resolve this problem you can visit your local health food store and purchase a synergistic super-food green supplement that can be mixed in a blender. A supplement that includes super greens such as Alfalfa, Spirulina, Chlorella, vegetables, fruits, enzymes and antioxidants.Such nutrition is beneficial as it ensures that the body is in a perfect state of PH balance for excellent health.

If you do have the time, here are some foods good for eyes. Incorporate a whole food diet rich in colorful, dark green leafy vegetables and fruits. These are ideal as they consist of antioxidants that fight the damaging effects of free radicals that have a negative effect on eye health. A great source of antioxidant rich foods are Spinach and Kale. The following are foods that improve eyesight: rich food sources of Lutein such as broccoli, peas and sweet corn. When it comes to vitamins, find a good nutritional supplement that consist of Omega-3 Fatty Acids and Vitamin E to promote eye health. It's essential especially in hot weather to stay hydrated. You can do this by drinking a lot of water. Water is a great way to detoxify the body which can remove toxins that interfere with eye health. Some additional foods for eyesight include high quality protein sources such as Almonds, Salmon and Turkey which are rich in vitamin A; a nutrient beneficial to eye health

You can incorporate whole grains into your diet. Avoid sugars and carbohydrates such as refined white flours commonly found in foods such as white bread. These foods increase the risk of age related vision disorders. Good substitutes are foods that are rich in fiber. Choose bread that is 100% whole grain as well as cereals that are rich in fiber. The benefit of such foods is that they improve the efficiency of our digestive system improving the process of elimination.The beneficial quality of fiber is such that it makes you full. From this point of view, it makes it easier to reduce your consumption of calories.Nutritional experts recommend that about 50% of your diet should account for about 100% of whole grain sources.

A lifetime of poor eyesight due to the negative effects of aging does not have to be your fate. Certain nutritional strategies such as incorporating the right foods like fruits and dark green leafy vegetables, super green food supplements, and nutrients such as Omega-3 Fatty acids, can help you prevent or reduce the likelihood of age related vision disorders. This helps you to give your eyes the nutritional support they need for a healthy vision that lasts a lifetime regardless of age.

The Diabetic Eye: Overview of Diabetic Retinopathy

So you're diagnosed with diabetes and your doctor recommended that you have your eyes checked regularly. It's actually due to the damage to the retina at the back of the eye which is a common complication of diabetes. If it is not given medical attention right away, it can get worse and even cause some loss of vision, or blindness in several cases.

What is diabetes?

The condition wherein the level of sugar (glucose) in the blood becomes higher than normal is called diabetes. It occurs when your body does not generate enough of the hormone insulin or because the insulin that is produced has a reduced effect. It is a grave disease that can cause problems such as heart disease, kidney failure, amputations and even diabetic eye disease.

What is diabetic eye disease?

Diabetic eye disease is a complication of diabetes that refers to a group of eye problems that can all cause severe vision loss or even blindness. The most common diabetic eye disease is diabetic retinopathy.

Diabetic Retinopathy

Known as the leading cause of blindness in American adults, this disease is the most serious complication of diabetes for the eye. It occurs when blood vessels in the retina change. At times, these vessels increase in size and leak fluid or even close off completely. In other cases, unusual new blood vessels grow on the surface of the retina. In this condition, both eyes are usually affected but during the early stages, people who have diabetic retinopathy often do not become aware of changes in their vision. As it progresses, it usually causes vision loss which in many cases can not be transosed or reversed anymore.

There are two types of diabetic retinopathy: nonproliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR).

Nonproliferative diabetic retinopathy is also called as background retinopathy. It is the earliest stage of the disease condition wherein the tiny blood vessels within the retina leak blood or fluid. This leaking of fluid causes swelling or formation of deposits in the retina. There are some cases wherein deposits of cholesterol or other fats from the blood may leak into the retina.

If you have NPDR, you may not require treatment immediately. However, it is important for your eye doctor to closely monitor your eyes to find out if you need treatment. It is also best to work with your diabetes doctor to determine if there are necessary supplement steps you can follow to improve your diabetes management.

If this diabetic complication advances, it can cause the larger blood vessels within the retina to become obstructed. This prompts the beginning of the proliferative stage.

Proliferative diabetic retinopathy (PDR) is a serious complication of diabetes mellitus.The obstruction in the retina can bring about areas to become starved of oxygen which is known as ischemia. When this occurs, the eye is comprised into budding new vessels, a process called neo-vascularization. However, these newly developed blood vessels are atypical and do not provide the retina with apt blood flow.

Wrinkling or detachment of the retina may also occur because these new vessels often come along with a scar tissue. Between the two types, PDR may cause more severe vision loss because it can affect both central and peripheral vision. If you have PDR, you will require apt surgical treatment. In some cases, surgery is also highly recommended for severe nonproliferative diabetic retinopathy.

Anyone with diabetes can acquire diabetic retinopathy. Between 40-45 percent of those with diagnosed diabetes have some degree of this complication. Here, it is important to have a yearly eye examination.

What Are Transitions Lenses?

“Transitions” are a trademarked brand. The actual lens is called a photochromic lens. When the clear (or almost clear) lens is exposed to direct sunlight it begins to darken. Depending for how long the lens is exposed to direct sunlight will determine how dark the lens becomes; the longer the exposure the darker.

Photochromic lenses can be added to your prescription eyeglasses with glass, polycarbonate or another highly durable plastic lens. Glass is typically custom made and will have microcrystalline silver chloride dispersed through. Depending on how thick the glass lens is will determine just how dark it becomes. Because the glass is already embedded with silver chloride, the lens will never be fully clear.

The photochromic properties in plastic lenses are slightly different. A plastic photochromic lens relations on organic photochromic molecules to achieve the reversible darkening effect. Unlike the glass lens, it is applied as a surface layer. Direct UV light activates and darkens the lens. The reason they do not darken indoors is because the UV exposure is minimal. Even when driving, car windows shield and block a decent amount of UV ligh which advances the photochromic lenses from fully darkening.

Once exposed to direct UV / sunlight, after the first minute the lenses will darken substantively and will continue to darken for fifteen minutes. The opposite is also true. Once removed from direct UV / sunlight it will begin to clear immediately. It will take up to 15 minutes to return to the non-exposed state.

Temperature has an effect when trying to achieve the darkest state of the lens. The colder the temperature the darker the lens. In very hot weather the lenses will not reach their darkest state – making these lense better for skiers rather than for beach-goers. In colder temperatures it will take the lenses longer to return to their non-exposed state.

There are some advantages and disadvantages to having photochromic lenses. They offer coverage for the different varying degrees of light that people are normally exposed to, they eliminate the need for having a pair of sunglasses (or prescription eyeglasses with tinting) and they absorb 100% UV radiation which causes macular degeneration. The downfalls are: it takes awhile for the lenses to reach their potential and then return to their normal state, weather and cloud coverage determine whether the lenses will reach their maximum. On a cloudy day, the lenses will NOT fully darken due to the lighter UV exposure and the lenses will not fully darken inside of a car due to the minimal UV exposure.

Deciding whether to order glasses with photochromic lenses is a matter of preference and will be determined by how and what you actually use them for. There are several brands available and it is recommended that you investigate which brands are sold by your optician.

Improving Vision Naturally – 4 Eye Depth Perception Enhancing Techniques

Interestingly, there are many sports that we play while a vital visual skill is used in helping us achieve better athletic performance on the field. For example, baseball player Mark McGuire depends on this ability to accurately judge distances and it is used when an athlete is passing a football, basketball or a hockey puck. We need it to navigate our environment when we are walking and driving a car. Additionally, this ability enables us to know where to aim or strike a ball. This important skill is called eye depth perception. What is depth perception? Depth perception is defined as the visual ability that helps us to determine the right distance between objects in a field.Without this skill it would be difficult or impossible to accurately judge differences between people and objects in all directions. If you are concerned that your depth perception skills are poor; here are some depth perception exercises to improve this visual ability:

1. For this particular technique, you will need two pens or two pencils. Hold the two pens or pencils in each hand in a horizontal or vertical position at a distance from each other. Then, stretch your arms out wide and by closing one eye; attempt to touch the tips of both pencils together. The objective of this technique is to enable you to judge the distance between two objects.

2. You will need beaded strings to perform this exercise. Take a long string about 15-20 feet long and connect at least several beads to this string. Connect one end of this string by simply tying it to a doorknob or if you prefer, you can use a piece of scotch tape or masking tape to stick one end of it on a wall. Make sure that it's at eye level. Hold the other end of the string and walk back as far as possible so that the string is fully extended. Hold this end of the string against the tip of your nose. Focus on the first bead. Did you notice that your eyes formed an X on the first bead? If you did, this means that your depth perception skills are good. If in the event of focusing on the first bead, you see an image of 3 strings appear instead of 2, continue focusing on the other beads further down the string until your eyes can produce the image of the X.Practice also moving your eyes from bead to bead up the string and from bead to bead down the string. The benefit of this exercise is that it shows you how to improve depth perception. Some additional benefits of this technique also include eye relaxation effects and an increase in the focusing power of the eyes.

Here are some additional depth perception activities that you can perform to improve
this important visual ability:

3. This routine requires a companion, a straw and a tooth pick. Have a partner hold a straw in a horizontal position at a distance of about 2 feet in front of you. By closing one of your eyes, take a tooth pick and insert it into one end of the straw hole. This exercise increases depth perception. Practice these techniques regularly about about 4 times a week and give them at least 30 days to notice a difference.

4. A research study by the University of Rochester suggests that video games actually do improve a person's depth perception. In the study, a comparison was drawn between the visual performance of video game enthusiasts who played action video games such as car racing and those who played board games. The games were played for a few hours for a period of about a month. Those who played board games did not notice any improvement in their depth perception skills however; the video game group noticed a 20% improvement in their visual skills.

Eye Depth perception equips us with the vital skills that play an important role in sports such as football, basketball and baseball. They aid us in our ability to get around in our environment when we are walking and driving our cars. The benefits include an increase in the focusing power of the eyes. Ultimately, they contribute to an enhanced ability to judge accurately; key skills critical to improved athletic performance on the sports field and in driving.

Myopia Treatment

What Is Myopia Treatment?

Myopia is also known as nearsightedness. It is also the most common issue that people have in fact, in recent years it has become even more prevalent. From 1971-1972 only 25% of the population had nearsightedness. In a study done between 1999 and 2004 that number rose to 41.6%.

The cause for this increase as well as the cause for the condition is unknown. It is however considered to be a refractive error in the eye.

There are some specialists that believe the cause could have due to the increase in computer usage and the eye fatigue that comes from sitting in front of the computer day after day. This coupled with a predisposition for myopia could be behind the increase.

Symptoms and Signs

It is not hard to figure out if you are having an issue with nearsightedness. A clear sign is having difficulty reading road signs you might also have difficulty focusing on other objects that are just as far away. Although up close there are no issues and you may do these tasks extremely well.

There are other symptoms including headaches, tired and hurting eyes which may all lead you to squinting.

Causes

While the ultimate cause for the condition is not known the mechanisms of the condition are known. Nearsightedness is caused when the eyeball is too long. This length is compared to the power the cornea has and the eye lens.

The mechanisms of this situation cause light to become focused just in front of the retina instead of on its surface.

It can also be caused when the lens of the eye or the cornea are overly curved in relation to the length of the eyeball. It is possible for both of these conditions to occur in combination. Myopia usually starts in early childhood years however there are times when it starts later in life and the condition can become stable or worsen over time.

The best way to prevent this and compensate for the symptoms is through myopia treatment.

Treatment

There are several different types of treatment options for Myopia. You can correct this easily with contact lens, glasses or refractive surgery.

Refractive surgery works by removing a layer of tissue from the cornea. The tissue removal causes the cornea to flatten and allows for the retina to receive light the way it needs to in order to focus on things viewed from a distance accurately. This particular surgery is known as photorefractive keratectomy.

Lasik is also a popular surgery used for Myopia treatment. This involves creating a flap on the cornea's surface. A layer of corneal tissue is removed and then the flap is returned.

Finally, there is another procedure called corneal refractive therapy. This involves using a solid type of contact lens that causes the eye to reshape. There are even implantable lenses that are surgically implanted and help to resolve myopia temporarily.

Whatever the myopia treatment you choose treating nearsightedness is easy and requires only a trip to the eye doctor to get started.
