Vision test includes using moving images of differing sizes on a touch-sensitive screen where user response to images that incrementally increase in size determines visual capability

摘要

The method of determining the vision capability of a person using movable images uses a touch sensitive display monitor (1) with movable images (2). The images used have different sizes, so that each stepped size increase is used to determine the users vision. The apparatus can be used with a personal computer. The images movement can be random and the speed of operation is selectable.
