Abstract
The invention is a filtering, transparent device for preventing damage to healthy eyes and for the prophylaxis and therapy of pseudophakic eyes and/or eyes with macular and retinal neurodegeneration and is the result of applying a yellow filter to the transparent or translucent surface(s) of the visor of a protective helmet, to protect the eyes from the short wavelengths of the visible spectrum (500 to 380 nm). The invention avoids the difficulties and risks of existing ways of protecting healthy eyes or eyes subjected to cataract surgery, and improve the protection of eyes suffering retinal neurodegeneration, simply by applying a filter to the transparent or translucent surface(s) of the visor of any protective helmet. The invention consists of combining the transparent or translucent surface(s) of the visor of any protective helmet with a yellow filter that absorbs short wavelengths of light from 500 to 380 nm.
