Abstract: People with (AMD) Adult Macular Degeneration have great difficulty seeing, because their damaged retina sees double vision and distortion. The vision loss is a deterioration of light sensing cells of the retina. Direct or reflecting sunlight and headlights cause extreme glaring and distortion. There are magnifying binocular-fitted eyeglasses for precise detail, and an eye patch, which entirely blocks out all vision, which puts strain and pressure on the dominant eye. Not much is offered to block bright glare, distorted images and double vision associated with AMD. This invention enables adults and children with AMD to self-apply a stick-on eyeglass multi-colored filter UV protectant disc, placed only in front of the affected eye's pupil, on the front of the eyeglass lens. An eye patch blocks all vision completely.
