One of computer usage negativity impact which ekstensif for health is eye trouble so-called as computer vision syndrome ( CVS).

According To The American Optometric Association, CVS is gathering of ocular symptom ( eye) and also non-okuler is arising after working in front of computer screen or terminal display video ( VDT).

Has not been known

Mechanism the happening of CVS has not fully is known, but anticipated is aliance from eye surface factor, accomodation, other factor outside eye, computer characteristic, and settlement of activity room.

Surface of eye the always wet because arranged in tear layer ( tear film) at CVS can experience trouble by area, like water use conditioner ( AC), fan, and degradation of blink reflex when working. Besides, surface of eye can experience trouble as result of producting decrease tear with increasing of age, existence of change of hormone at woman, existence of certain disease or consumption of certain drug ( for example antihistamine or drug anti-hipertensi), and contact lens usage.

Accomodation or change of eye structure can see in focus to see short distance. Letter at very differing in computer screen at text in paper because lapped over to pixels, or structured points formed letter or number. To see letter/number at computer screen, continuous eye accommodates causing fatigue or eyestrain. the profit, usually change at accomodation haves the character of reversible by the end of day or at red letter day. Some expert assumes that accomodation as result of usage of computer can stimulate miopisation, but has not been proved with research.

Pain In Bone or neck muscle rigour, shoulder, and back happened as result of movement of head, neck, and shoulder forwards, is tending to be done by computer consumer to see clearer.
