| 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). n 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. n 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. |
