If you spend a lot of time each day in front of a computer, you are likely to experience symptoms of computer vision syndrome (CVS). CVS is a term used to describe a collection of symptoms caused by prolonged computer use. Symptoms appear because the eyes and brain react differently to words on a computer screen than they do to printed text. With more and more adults and children using computers on a daily basis, CVS has become a common vision complication. And an increasing number of people are seeking relief from eyestrain and irritation caused by CVS.
Definition: Asthenopia is a word often used in the eye care profession to describe a collection of symptoms that produce eye fatigue or tiredness, usually brought on by using the eyes. Asthenopia may also produce symptoms of pain, eye strain, tiredness and headaches. Symptoms often occur after concentrating on a visually straining activity, such as reading, which causes the inner eye muscles to tighten.
Symptoms of CVS
People who suffer from CVS may experience the following symptoms:- Dry eyes
- Headaches
- Eye irritation
- Blurred vision
- Light sensitivity
- Temporary inability to focus on a distant object (pseudomyopia)
- Double vision
- Squinting
- Neck and shoulder pain
Treatment of computer vision syndrome
If you think you might be feeling some of the symptoms of CVS, you may benefit from a pair of computer glasses. Computer glasses are prescription glasses specially designed to allow patients to work comfortably on a computer. Computer work involves focusing the eyes at a close distance. Standard reading glasses are usually not enough to alleviate symptoms of CVS, as computer monitors are usually placed a little further away than the comfortable reading distance. Computer glasses allow a person to easily focus on the distance of the computer screen. Contact lens wearers may even need to wear glasses over their contacts while using the computer.Definition: Asthenopia is a word often used in the eye care profession to describe a collection of symptoms that produce eye fatigue or tiredness, usually brought on by using the eyes.

Asthenopia is sometimes caused by basic vision problems, such as uncorrected refractive errors.
If you are experiencing symptoms of asthenopia, try to give your eyes a break once every hour by focusing on an object in the distance.
