What cause us to wear glasses when we look or use the computer or television for a long period of time

Thank you for using our ASK! service.

You asked what causes us to become short-sighted when we use the computer or television for a long period of time. The short answer to this is because of increased time spent focused on a close object, which causes the eye to get "stuck" in the close-up focus position and can no longer focus on distant objects. Therefore it is not just computers or television that causes short-sightedness but any form of activity that involves focusing the eye on a close object, for example, reading in poor lighting.
