VISUAL DISORDERS

The problem

The computer can work to put the extraordinary muscles of the eyes to a considerable effort:
If the contrasts between light text on the screen, on a document and the symbols of the keyboard is too high may be up to 25,000 movements a day to adapt to light.
If you set your eyes on objects very close long as a screen. The muscles of the eyes are at rest if distant objects observed more than 6 meters.
If monitors and documents to be read are not placed at about the same distance, the eye muscles are forced to a continuous change of focus.

See a doctor regularly, particularly after 45 years.
