Now days, many of us have jobs activities that require us to look at computer screens for very time. That can put a real strain on your eyes. Many of us spend most of our working life looking at a computer screen. But this is not good news for our eyesight. Here, we explain the   side effect of computer to eye health and vision and what you can do to mitigate the damage.

Most eye problem caused by computer use, fall under the heading computer vision syndrome (CVS).

It is not just one specific problem. Instead, it includes a whole range of eye strain and pain. Investigation shown that between rang of 50% and 90% of people who work with computer have at least some symptoms. Working adults are not the only ones affected. Kids who stare at tablets, phones or use computers during the day at school can have issues, too, especially if the lighting and their posture are less than ideal.

CVS is similar to carpal tunnel syndrome and other repetitive motion injuries you might get at work. It happens because your eyes follow the same path over and over. And it can get worse the longer you continue the movement. When you work with a computer, your eyes have to focus and refocus all time. They move back and forth as you read. You may have to look down at papers and then back up to type. Your eyes respond to changing images on the screen to create, so your brain can process what you are seeing. All these jobs need a lot of strength from your eye muscles. And to make things worse, unlike a book or piece of paper, the screen adds contrast, flicker, and glare.

You are more likely to have complications if you already have eye trouble, if you want glasses but do not have them, or if you wear the wrong recommendation for computer use. While cutting down dramatically on screen use might be the ideal treatment for strained eyes, it is not practical for people with desk-based jobs. There are still countless practical steps you can take to reduce the effects of computer use on eye health and vision. Set an alarm every 30 minutes to give your eyes a break. Take a walk across the studio and back to correct poor posture at the same time. Screen glare can cause eye strain, but good lighting can help reduce the effects. Adjust the contrast settings on your computer monitor so that the screen feels relaxed to look at. Eliminate anything that causes glare, such as desk illuminations, and position your screen so that it is not straight in front of or behind a window. If you have an untreated existing eye problem like myopia or hypermetropia, computer use is likely to worsen the effects. Regular eye tests will discover any vision problems and certify that your eyes are treated with the appropriate prescription. Specially designed eyeglasses can dramatically reduce the effects of computer use on eye health and vision. Aiding the eye to focus on the screen without strain, your computer glasses might have a different treatment from reading glasses, since the object of your focus is a different distance away. Computer glasses can also have anti-reflective coatings and even tinted lenses to assistance reduce glare.
