Visual fatigue checker for keeping eyes healthy -to test visual strain caused by PC operations-

Abstract

Visual strain will be caused by PC operations for a long time a day, which might fail health of human eyes if it continues a week or more. Any action to check it by oneself needs to be done every time PC operations are continued for a multiple of hours. We propose a visual fatigue checker to simply test the fatigue of human eyes and to help us to resume visual health from the fatigue, if any, with some expected recovery time.
