Abstract
A device is provided for the treatment and prophylaxis of healthy eyes, pseudoaphakic eyes and/or eyes suffering macular and retinal degeneration that comprises a yellow filter applied to a conventional illumination system to protect them from short wavelengths of the visible spectrum under 500 nm and preferably in the range of 350 nm to 500 nm. This device the difficulties and risks of existing ways of protecting eyes undergoing cataract surgery and prevents or improves the degeneration of healthy eyes and those suffering neurodegeneration by the simple application of a protective filter to any lighting system. Embodiments of the invention comprise combining a conventional light source with a conventional yellow filter that absorbs wavelengths of light shorter than 500 nm so that the filter completely covers the illumination source.
