Over use of eye muscles causes eye strain. Normally any muscle held in one position for a long time will cause strain. Concentrating on a particular task like reading, working with computer or watching television for a long period of time will make the eye muscles tighten up which makes the eye to feel the irritations, dry and uncomfortable.
Eye strain stems from overuse. To refresh the eye, refocus once or twice in an hour or take a five minutes break from whatever work we are doing. Close the eyes for few minutes or some few seconds which reduces the eye strain. Blink as much as you can which soothes the eye and moistens. An alternative for blinking is artificial tears which remoistens the eye and releases the strain. Certain eye products like Murine and Visine must be avoided since they can dry the eyes out further. People working with computer suffer from eye strain; the contrast in the screen must be changed and the position of the computer screen must be placed in such a way that window light doesn’t bounce off and create glare on the screen.
