Aided Recovery from Visual Compensation for Visual Loss

Abstract

Loss of the central visual field, or foveal scotoma, due to accidental exposure to laser light or macular disease can cause serious impairments in visually guided performance by either long lasting afterimages from visible radiation or permanent or degenerative injury to retinal cells. Fovea scotomas also interfere with normal control of eye fixations and saccades during visual tasks. Development of an electronic aid is described as a compensation for central field losses which would be suitable for vehicle and person portability. The aid is designed to compensate for performance loss expected to accompany sudden or progressive loss of central vision.
