In fact, wearing glasses is not only a matter of money, but a matter of inconvenience. One has to spend much time in the maintenance of these glasses. For example, he has to find the glasses that he has left somewhere which he forgets. And more troubles will be involved in the using of contacts that are more easily to get lost. Of course, one may choose to receive LASIK surgery, but he may encounter something unsure, such as, some complications, and he has to pay a lot of money. Fortunately, these problems aforesaid can be solved by some natural methods on which one needs to pay nothing.

What is the main cause of eye problems? The answer is fatigue. It is true that too much fatigue in the body is the main cause of eye problems, whereas the best way to eliminate fatigue is to sleep. Thus, one needs to get sufficient sleep if he wants to have very good vision. It is suggested that one should keep a regular biological clock and sleep about 7 hours each night. With enough sleep, one’s eyes will not get so strained as they are under conditions of insufficient sleep.

Another cause of eye problems is unbalanced diet. People may get some eye problems for the reason of unbalanced diet. Generally, eating too much of something and too little of others may cause very serious problems in one’s body and eyes. For example, eating too much fat and little natural goods may be harmful for his eyes. In order to ingest balanced nutrition, one is suggested to eat some vegetables, fruits and proteins, etc.

Vision improvement through eye exercises

In general, the eye’s focus and pupil size are under control of the internal muscles, while external muscles have more responsibilities. External muscles direct the eyes to the right point and keep the retinal image in constant slight motion. In fact, both internal and external muscles are quite important in maintaining good eye health.

Like any other muscle system, eye muscles are subject to fatigue after continuously use without breaks. They can be fatigued if the eyes are used for prolonged ocular activity. In addition, those activities that require added effort and concentration can cause eye fatigue more easily. After proper rest, eye muscles can recover their optimal levels of function.

Eye muscles do need proper rest and relaxation, similar to other muscles of the body. Excessive eye use can push eye muscles to their limit, which can lead to vision problems. This abuse of the eye prevents eye muscles from restoring to their normal state.

Experts have suggested that eye muscles can benefit from exercises, just like the body. A New York ophthalmologist named Dr. William Bates had developed a series of eye exercises for vision improvement, which can eliminate eyeglasses, contact lenses and surgery.

Dr. Bates thought that people with poor vision can benefit from those exercises, without the help of eyewear and vision surgery. In his mind, eye problems were caused by eye stress, tension as well as laziness. Eyeglasses and contact lenses could actually increase the laziness of the eyes. In fact, those methods initiated by Dr. Bates were first introduced in the early 1900s. And until now, many people have been taking these proven methods.

Eye muscles fixed on one particular scene has been believed to cause strain to the eyes. In this consideration, it is quite reasonable that eye relaxation can provide an improvement between the optic nerve and brain, which brings clear vision.

Remarkable visual improvements have been reported on all groups, such as those are nearsighted, farsighted, astigmatic as well as people with lazy eyes. Dr. Bates’ exercises have proven to be effective, although medicine has simply ignored the exercises’ benefits.

Palming, swinging and daily color awareness are some of the Dr. Bates’ exercises, most of which should be performed for about 30 minutes every day.

Computer vision syndrome is a serious problem for the millions of people. Due to long hours on the computers, large percent of computer users (by some research between 60 % and 90%) are prone to Computer Vision Syndrome (CVS).

A variety of means to ease computer eye strain

About 50% to 90% of computer workers are being affected by bothersome CVS symptoms such as eye strain. Researches have revealed that this discomfort can cause physical fatigue, decreased productivity and increased work mistakes. The following is a detailed introduction on how to address CVS.

The National Institute of Occupational Safety and Health (NIOSH) recommends people to take a computer eye exam before computer work, and tell the doctor your computer work frequency. Excessive light from either exterior sunshine or interior lighting brings eye strain at a higher possibility. The proper lighting should be about half of that in most offices, so that you should close drapes, shades or blinds to reduce outside light and use lower intensity bulbs and tubes.

Light glare and reflections from walls and the computer screen also contribute to eye strain. Many convenient ways are available to solve this problem, such as setting up an anti-glare screen on your monitor, painting bright walls into dark and applying anti-reflective coating to your lenses.

Liquid crystal display (LCD) is built with an anti-glare surface, which is beyond a cathode ray tube monitor (CRT). Even set to the highest possible refresh rate, CRT screens may cause image flicker and lead to eye strain. For LCD, a higher refresh rate and larger size are more helpful.

Most displays provide a series of settings for adjustments. The screen brightness should be the same as the ambient environment, and the contrast between the screen background and the on-screen words should be high. Text size and color can also be adjusted.

Most people blink less frequently during attentive computer work, which may lead to high rate of dry eye. Long period of non-blinking phase speeds the evaporation of tears so that your eyes can not get rewetted in time. Dry environments can also bring dry eye problems. You can ask your doctor for artificial tears to ease this problem. Lubricating drops are not capable of reducing dryness and irritation.

Two ways of exercising your eyes to reduce focusing fatigue are widely applied. One way is gazing at a distance object outside every 20 minutes, which relieves the eye’s focusing muscles. The other way is to alternately look at a distance object and a close thing. Frequent blinking is also needed during these exercises.

The NIOSH advocates that more frequent small breaks during the work day can sharply reduce eye strain and discomfort. It is also recommended to divide long breaks into several short breaks. During the break, you can stretch your arms, legs, back, neck, shoulders or do other quick sequence of exercises.

Many factors that involve your computer workstation may also affect your comfort. Your desk lamp should not shine into your eyes or onto the computer screen. You should properly place your chair at proper height to get a suitable posture. Ergonomic furniture can also provide useful help.

A variety of computer glasses including single vision type, bifocals and trifocals offer the greatest comfort for computer use.
