ABSTRACT:
Directly modulating a beam of photons onto the retinas of patients who have vision impairment or blindness. Its purpose is to supply enough imaging energy to retinal prosthetics implanted in the eye which operate essentially by having light, activating photoreceptors, or photoelectrical material. Providing sufficient light amplification logarithmically. Output light level being at a safe level. Providing balanced biphasic stimulation with no net charge injection into the eye. Optical and electronic magnification is used for the image with an optical zoom lens. It would not be feasible to zoom in on items of particular interest or necessity. Without proper adjustment, improper threshold amplitudes would obtain, also uncomfortable maximum thresholds. Proper adjustment for the threshold amplitudes and maximum comfortable thresholds is provided. The individual stimulation sites in the retina give different color perceptions, then colors of the viewed scene is correlated with specific stimulation sites to provide color vision.
