Abstract
The object of the invention is a contact lens for pseudo-aphakic eyes and/or eyes with macular and retinal degeneration, its main characteristic being the application of a yellow filter to a standard contact lens, with the purpose of protecting the eye from the short wavelength radiation of the visible spectrum (lower than 500 nm). This invention avoids the difficulties and risks of existing techniques, providing protection to the cataract-operated eye and improving natural protection in eyes with retinal neuro-degeneration, through the simple application of a contact lens. The invention consists of the combination of a standard contact lens and yellow filter, which absorbs short wavelengths of 350/500 nm, both its components being appropriate for use in the human eye.
