Vision enhancement using a short wavelength light-absorbing filter.
This report illustrates photographically the adverse influence of short wavelength-induced light-scattering and autofluorescence on image quality, and the improvement of image quality that results by filtering out light wavelengths shorter than 480 nm. It provides additional data on the improvement in human vision (under conditions of excessive intraocular light-scattering and fluorescence) by filters that prevent short wavelength radiant energy from entering the eye.
