At first it is necessary to provide appropriate lighting of workplace. Screen of monitor must be evenly illuminated. This way eyes will get tired less. It is not recommended to work on computer in dark or scantily lit room. It is necessary to avoid insufficient or excess illumination. The most rational approach is dimmed and diffused light. Local light during work on computer is not required - room light is enough. You should have in view that it is better not to equip workplace with fluorescent lamp.

There is no single type of computer spectacles, which all people can use. Therefore one should consult with doctor- ophthalmologist before purchase of spectacles. Lenses for computer can be bought only in specialized store. Feeling of overstrain and tiredness appear not only because of glares but because of absence of breaks during work. Ideally one should rest 10-15 minutes every half hour. It is better to devote the break to short eye training. You can close eyes for 2-3 minutes. Or to look upward, downward, right or left. Then close eyes tight for 3-5 seconds and open eyes widely. It is obligatory to make several squats and turns of body to different sides. Or just to walk along the office. For example visit your colleagues to discuss working issues. Also try to turn computer to guardian of your eyesight. Many users have special computer program with alarm clock. It reminds user about necessity of breaks. There is a rather simple recipe for struggle with exertion and reddening of tired eyes. Put pinch of dry tea in 2 small gauze bags. Then drop them in boiling water. After that take the bags out and cool them down. Finally put them on eyes.
