Computer Glasses: Relieving Your Eye Fatigue

By: DerikBriany

When you work at a computer for long periods, and not having a relaxation, it is very common to experience eye discomforts, such as dry eyes, eye strain, blurred vision and double vision. These symptoms are so-called Computer Vision Syndrome (CVS).

 

In the beginning, you may think that you haven't been accustomed to the new working environments. So you try your best to adjust yourself. But to your doubt, the discomforts can't be lessened essentially. Why do we have the feelings?

 

The causes are various. Glare is the most important factor. Glare from overhead lights and screen has attributed to dry eyes. Poor contrast between lighting and computer screen also make eyes uncomfortable. Squinting, infrequent blinking, focusing on the screen for long periods of time and ultraviolet radiation from the screen are easy to result in dry eyes, too. Besides, high energy wavelengths produced by artificial light sources, such as fluorescent bulbs and computer screens, contribute to eye strain and fatigue. Prolonged, concentrated viewing of computer screens typically results in less blinking, which leads to dry eyes. Thus your eyes feel tired and can't see the things clearly.

In regard to this situation, what can computer users do? For some starters, they may have a comprehensive eye exam to rule out vision problems and update their prescription eyeglasses in time. However, studies show that even smaller inaccuracies in your prescription lenses can contribute to bigger computer vision problems. If you don't need prescription eyeglasses for most tasks and continue to experience eye discomfort, you can consider purchasing computer glasses.

Computer glasses are used for computer work which is different from the glasses they use for other common visual needs. In other cases, they may have a vision disorder that would not need a vision correction if they don't perform a demanding visual job such as at the computer. Even people that have excellent vision may need glasses just for computer use.

Computer glasses differ from regular eyeglasses or reading glasses in a number of ways to optimize your eyesight when viewing your computer screen. Computer glasses put the optimum lens power for viewing your computer screen right where you need for a clear, wide field of view without the need for excessive focusing effort or unhealthful postures.

Computer glasses have single vision lenses with a modified lens power prescribed to give the most comfortable vision at the user's computer screen. This lens power relaxes the amount of accommodation required to keep objects focusing on the distance of the computer screen and provides the largest field of view. Single vision computer glasses reduce the risk of eye strain, blurred vision and unnatural posture that can cause neck and back pain, and can be used comfortably by young and old computer users alike. Other lenses used for computer glasses include occupational bifocal, trifocal lenses occupational progressive lens, etc. Some research also reviews computer glasses can significantly increase workers' productivity.

So you needn't worry about your eye fatigue any more. Computer glasses will help you use computers in comfort.
