The purpose of Home Vision Testing is to encourage early detection and treatment of eye disorders.
These tests are not a substitute for a complete eye examination by your eye doctor. However, they may help you discover a vision problem that needs medical attention.
Remember, most eye disorders can be effectively treated if detected early. Unfortunately many eye diseases are detected too late for effective treatment.
It is estimated that one third of all new blindness is potentially avoidable if people take full advantage of early diagnosis and treatment. Therefore, you should perform these tests periodically.
