Resumen
Element for the protection and therapy of eyes applied to the transparent vertical surfaces of buildings. The invention is prepared by applying a yellow pigmented filter to the transparent or translucent surfaces of a building in which a subject may be found, and is designed to protect the eyes from the short wavelengths of the visible spectrum in the range 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 improves the protection of eyes suffering neurodegeneration, simply by applying a filter to the transparent or translucent surfaces of any building in which a subject may be found to provide protection against the neurodegenerative components of light (short wavelengths).
