Abstract
The subject of the invention is a covering filtering material for protecting eyes which are healthy, pseudo-aphakic (operated for cataracts) and/or having retinal degeneratiion under short wavelengths, which results from the application of a filter with yellow pigmentation on any covering, coating or screening material with the purpose of protecting the eyes from the short wavelengths of visible spectrum from 500 to 380 nm which cause retinal degeneration. By way of example, this element may be applied in materials intended for manufacturing awnings, parasols or insulating materials or protection screens of any type. This invention avoids the difficulties and risks of the existing techniques for providing this protection for healthy and cataract-operated eyes and for improving protection for eyes undergoing neurodegenerative processes, achieving this with the simple application of a filter to common covering, coating or screening materials, thereby furnishing additional protection against neurodegenerative agents found in light (short wavelengths).
