Abstract
The invention relates to an ocular device which permits the avoidance of the phenomenon of photophobia and the method for production thereof. The device comprises one or more chromophores which absorb light in the wavelengths between 400 and 575 nm (blue-green light) and which are dispersed, after the placement in or on the eye, in the surrounding body fluids in several weeks to several months depending on the concentration of the chromophores. The device is produced by conditioning of the non-colored ocular device in an aqueous solution of the chromophore(s) in the shade.
