People who spend much time on the computer each day will doubtlessly encounter some discomfort in their eyes. In other words, they will suffer CVS (computer vision syndrome). The most common symptoms of CVS are eyestrain, blurred vision, double vision, excessive tears, dry eyes and excessive blinking or squinting. These visual problems also can result in physical problems such as headaches and neck or should pain. Read on the following article, there are some suggestions that can help you reduce some effects of CVSS.

Firstly, an anti-reflective coating (AR Coat) on the lenses of glasses will reduce the glare coming at you and from behind you that causes eyestrain. Someone believes that glare screen filters may be helpful for some people, but they will not solve your computer vision problems. Because they only affect glare from the computer screen, not the problems caused by the constant refocusing the eyes must do when working on a computer.

Secondly, Proper lighting can reduce eyestrain and glare. The brightness of the monitor should be adjusted to the intensity that is comfortable to the eyes. You also should adjust the contrast between the characters on the monitor and the background so the letters are easily read. Minimize reflected glare on the monitor by using window shades or curtains and dimmer switches on lights. Bright lights sources also should be removed from peripheral vision.

Thirdly, Take frequent breaks and keep artificial tears-lubricant eye drops-handy at your desk. Look away from your computer screen every 10-15 seconds on a distant object outside or down the hallway or get up and take a short walk. Everyone tends to stare at the computer and blink less than normal. Staring and decreased blinking dry the eyes out. Taking frequent breaks allows normal blinking and better wetting of the eyes.

Lastly, Position the monitor in an ergonomically correct position. The monitor should be located 16 inches to 30 inches from your eyes, depending on how large the screen is and how good your vision is. Most people find it is more comfortable to watch a screen 20 inches to 26 inches away. Moreover, maintain good posture at your desk, keep your back straight and your shoulder back.

It is found that a lot of people are suffering from color blindness, one of the commonest vision problems in the world. The reasons why people suffer from color blindness varies a lot, but the direct reason is- some problems occurred on the glasses frames producing of photosensitive pigments in the eyes. Sufferers of this problem may have less of these pigments. If so, the pictures captured by eyes can not be well reflected and expounded by their eyes. And the result is sufferers of this problem can not tell certain colors.

And the severity of color blindness varies a lot in different sufferers. Some of them may see much better than others, but all of them can not tell colors accurately. For example, some sufferers can not tell the difference between red and blue and others can not tell other colors. Or there are also some sufferers who can not tell any other colors- their vision field are colored in grey, white only.

It is also found that sufferers of color blindness may have different symptoms. Some people have very obvious symptoms and their lives are greatly affected, while others have never noticed the existence of this problem. In other words, some people are completely color blinded, while others are partially color blinded. Unfortunately, there is no effective way for this problem till now.

People’s lens becomes blurry on and on if they suffer from cataract. This problem is one of the most serious eye diseases and will lead to blindness in most cases. For this, some eye procedures can help a lot. Some of the commonest ways are lens implants, through which, sufferer’s cloudy lens will be replaced. And many receivers’ visions are rebuilt.

This implanting procedure is usually called IOL, the abbreviation of intraocular lens implant, which can also be categorized into different groups. Since the emergence of first IOL, more and more achievements are made in the field. There are now IOL of various kinds.

One of the most conventional IOL is a standard procedure, which can offer receivers great vision clarity in most cases. But there are still some problems on this procedure- receivers can not regain their natural vision as they ever have. It can only solve vision problems partly- the distant or nearby vision problems only. And the situation is much worse when receivers have astigmatism. This is also why some patients are still in need of glasses after standard IOL.

But there are much better options. Multi-focal IOL procedure can offer much better results. This procedure ensures that receivers can enjoy much wider and clearer vision field. But there is a possibility that receivers may get complications of some kinds.

Other IOL can also offer nice results. For example, crystalens procedure is very effective in offering both far and intermediate vision. This lens can adjust its power according to people’s movement.

In a word, there is no IOL procedures that can ensure perfect vision results and patients can not get rid of eyeglass in some cases. But it is still a good option.

Especially, when people are watching or looking at computer monitors, they should try to blink at interval, so as to avoid eye dryness. In addition, people should also make sure that their eyelids are clean and no waste is accumulated. Too much waste can affect the production of tears.

In other cases, dryness can also be caused by lack of certain of substances or nutrients. For this, people can intake supplements of certain kinds, like Vitamin C, Vitamin B, etc. some fruits can also do a perfect job in prevent eye dryness, like banana.

Dry eye causes and treatments

Eye dryness is one of the commonest problems among people with certain vision errors. The direct reason for this is- in eyes are insufficient or no tears, which can be used to lubricate eye tissues. In addition, tears can offer protection for eyes- in which are some special ingredients that can be used to kill certain bacteria or harmful microbes.

Therefore, if tears can not be produced in certain amount, eyes will suffer a lot. One of the commonest symptoms is pain, or some people may even suffer from eye infection or inflammation, and many peoples’ vision is greatly affected as a result.

Some surveys reveal that dry eye is very common among the massive people and the situation will be much worse among people in certain age groups, like the aged. In other words, eye dryness can be much worse as people age. One of the reasons is people who are over 60 are more vulnerable to cataracts and glaucoma, which can cause many complications, like eye dryness.

Usually, sufferers of dry eyes will feel irritation in their eyes. And the best treatment for this is to find ways to offer eyes more tears, either natural or manmade. When eyes can not produce sufficient tears automatically, some artificial tears are ideal alternatives. These liquid can help relieve symptoms caused by this problem. When eyes are well nurtured to some extent, tear glands will re-produce natural tear gradually.

If the symptom is too serious, some other special tears are needed, like topical steroid drops. These liquids can be used to cure some eye inflammation or injury first and then offer eyes more care. When some irritating symptoms are eliminated, natural tears will be re-produced gradually.

It is also now found that some problems, like inflammation, on eye lids are main causes for eye dryness. Therefore, it is needed to prevent any infection or inflammation on eye lids. Doing so can reduce eye dryness to a relatively small range.

In word, dryness is common and will not cause serious results in most cases. But people should place great emphasis on it, for it may also lead to further infections and problems in some cases.

In the past, patients with Keratoconus were told that they had little chance to heal the cornea and they had to take corneal transplants to relieve from this kind of eye diseases. However, through researchers’ and eye doctors’ hard work and researches, patients are lucky now that they can have some less invasive ways to treat Keratoconus. The following will give some introduction on Keratoconus and the new treatments that can give hope to Keratoconus patients.

First, let’s learn about how the Keratoconus is caused. This is mainly due to the free radicals which can invade the eye and create a reactive species. Then the species break down and cause weakness, which can make the cornea to herniate and lead to Keratoconus. Though at the beginning, people may not feel terrible with this eye disease, after several years, it may cause people to blindness. It is a common mistake that most of patients do not pay attention to Keratoconus at the beginning, but after the disease spreads from one eye to another, they find they are in a difficult position to deal with it.

In order to help people know more about Keratoconus, the following will list out some symptoms of this eye disease: people feel their eyes itchy, and there are some discomforts and disturbances with their eyesight; as they feel eyes uncomfortable, they rub the eyes or squint too much; with time pass by, they find they have some problems in seeing things clearly and they have to face seeing troubles.

Researches show C3-R is a very effective and less invasive way to treat Keratoconus, which is also regarded as hope for Keratoconus patients. With G3-R treatment, the weakened and damaged place in the cornea can be strengthened. Maybe you think this treatment will be very complicated, though not as complicated as cornea transplant. Actually not. It is only 30 minutes needed for this treatment, but for the following 2 to 4 month, the cornea can be strengthened. Do patients need to have more applications? No. For most patients, only one application is enough, and for patients with severe Keratoconus, they can have two applications.

Besides C3-R treatment, eye doctors now also have some other treatments to achieve a good effect. Corneal collagen crosslinking with Riboflavin have been proved to be effective to improve people’s vision. And Intacts, and/ or CK can be helpful to improve the eyesight as well.

Many people may have an experience of a twitch or spasm in the upper or lower eyelid. This annoying condition has two different types: blepharospasm and hemifacial spasm. Occurring in both eyes, the former type is more serious that it can indicate a more severe problem. And hemifacial spasm always affects only one eye and thus is less serious. This article covers a wide range of information about eye twitching, including causes, treatments, cures and remedies.

Eye twitching is closely linked with one’s lifestyle. Until now, researches have not yet found one or two universal reasons of eye twitches. Potential causes of eye twitching include lack of sleep, stress, fatigue, screens, vitamin deficiency, eye strain, allergies, compresses nerve, medication, withdrawal, neurological disorder and so forth. In order to search out a specific reason, patients have to check these listed factors one by one.

It is always true that different causes require different cures. For example, if the eye twitching is caused by inadequate sleep, it is helpful to start exercising, take 5-HTP or anything to get a full night of rest. Stress-caused eye twitches require patients to find a hobby, start mediating or anything to lessen the stress levels. When it comes to fatigue, it is necessary to take a break from the thing that causes fatigue. People should not stare on a computer screen or TV screen for a long time. They are highly encouraged to take a 1-2 minute break every 15 minutes.

A HEPA filter or allergy medication can be used to eliminate symptoms of eye twitching caused by allergies. When eye twitching is caused by some medications being taken, patients should stop them immediately and consult their doctor about details. Neurological disorder requires patients to see a doctor to receive comprehensive tests.

Eye twitches can be quite bothersome and even affect appearance. It is necessary to find out its real cause, which can lead to appropriate treatment.

What’s strabismus? If you run into the condition that one eye sees clearer than the other, you are in great danger of strabismus. At that time, you may probably use the stronger eye more often. As a result, the stronger one will turn bad gradually. Meanwhile, as the weaker eye is not used quite often, its muscle becomes beef-witted and being out of good use. So you unconsciously see with the stronger eye only. The process will come into a vicious circle and your eyesight can be badly damaged in the end.

Actually, everyone has the problem of strabismus more or less. The most important thing we can do is to find out which eye is weak-seeing and to take some measures to balance the sight of both two eyes.

How to know whether you’re strabismus or not? The test is quite simple. Cover one eye and see a fixed object, then change to cover the other one. Compare the effects of the two eyes when seeing and then you can determine which eye is weaker.

After you understand the situation in which the two eyes are, you can train the weaker eye to function well at the right position. For a long time, you can achieve proper eyesight for your bad eye.

There’re many physical ways to improve vision, but perseverance is the biggest factor leading to good eyesight. So you should always keep your eyes out of tiredness. We list some simple exercises as follows, and you can choose one or two to do it every now and then.

1. Hold a pair of crossed chopstick, and see from one side of the horizontal chopstick to the other side, then back to the intersection. Browse straightly to the top of the vertical chopstick and down to the bottom. Repeat them seven or eight times. This exercise is quite good for muscles relaxing.

1. Take two chopsticks in the hands, one is three inches directly away from your nose and the other is at arm’s length. Move the farther stick towards your eyes, and keep attention on it. You can see the closer stick to separates into two. So is the same effect to the closer one. Do the exercises for a few times one day, and you can improve your vision.

1. Some ball games like table tennis are also beneficial for making eyesight better. If you can move your eyes every now and then, muscles can of course be trained well.

1. Brain plays a great role, too. You’d better reminisce or imagine object with your brain as if you are seeing with eyes. It will reduce the task of eyes. Say that in another way, eyes can be protected to some extent.

When there are some disorders or diseases on our eyes, the cornea shape will change. So doctor uses corneal topography to map the cornea to check Keratoconus and other progressive eye diseases. And it is proved corneal topography is one of the best way to test the cornea and diagnosis of eye diseases. The following will give some introduction on how to use corneal topography to check Keratoconus.

For people with healthy cornea, the cornea in the corneal topography is smooth and flat, and there is a 90 degree axes perpendicular in the cornea. And if there is any irregularities, that means there are some problems with the cornea. For example, irregular astigmatisms can be diagnosed if there is steepening or irregular shaping of the axes. When doctors use corneal topography to check Keratoconus, they can make a judgment from “Inferior Steepening”. For people who have corneal astigmatism, their shape of the cornea is like a football, while for normal ones, it should be round and smooth.

In addition, Keratoconus has some similarities with Pellucid Marginal Degeneration (PMD) from the corneal topography, which may cause people some confusion about them. Dr. Schalaeppi discovered PMD in 1957. Known as the peripheral form of Keratoconus, PMD means a lobster claw pattern by breaking down of the cornea. So we can see PMD and Keratoconus are in the same family and not easy to distinguish them. However, PMD still has its own specific feature. You can distinguish PMD from the steepening, which is from the outer margin of the cornea heading inwards, like pinching the center. And the signs of PMD are as following: Compared with Keratoconus, people can not feel pain with PMD. However, they can feel their visual distortions. In addition, there is no vascularization of the cornea and no scarring. And there is lobster claw formation with PMD.

Just as other eye diseases, the regular test at the eye doctor is critical for Keratoconus. Therefore, visit your eye doctor at a regular time and have a baseline corneal topography. The corneal topography can tell you if you are far away or bothered from Keratoconus. If you are unlucky to have this kind of eye disease, the test can help you to treat or stop the progression of Keratoconus in time, and finally to help you to have a good treating result. So please don’t forget to visit your eye doctor and have your eyes checked at a regular time.
