Abstract
An exercise device for improving poor visual acuity is disclosed in which a subject must identify randomly chosen figures of minimal visual stimulus projected in a darkened chamber. Earphones are provided to aid in the isolation of the subject and provide audio feedback. The device provides effective treatment for certain eye conditions involving poor acuity and is particularly effective in treating the eye condition known as amblyopia.
Claims24
An ocular stimulator unit to improve the non-refractive acuity of a user's eyes comprising:
- a solitary visual target presented without interference from other visual stimulus;
- means for randomly selecting and generating at least one of a number of various figures to be displayed on said visual target;
- a keyboard through which the user can respond to the various figures seen on the visual target;
- means for comparing said displayed figure with responses from said keyboard;
- means for informing the user of the correctness or incorrectness of said response;
- and
- wherein means are provided for adjusting the apparent size of the displayed figure to maintain the figure displayed at a level of minimal discernable size.
A method for use in improving the non-refractive acuity of a user's eye, said method comprising;
- placing before the user's eye a solitary visual target presented without interference from other visual stimulus;
- causing the visual target to randomly display at least one of a number of predetermined characters;
- providing the user with keyboard means capable of being so actuated by the user as to denote any of said characters the user believes he or she discerns upon the visual target;
- comparing the character denoted through the keyboard with the displayed character to detect and signify whether they coincide with each other;
- and
- providing means for adjusting the apparent size of said displayed character to maintain the character displayed at a level of minimal discernable size.
