Abstract
There is provided an optical lens for correcting color vision for always and adequately correcting and normalizing anomalous color vision. Wavelength where a spectral sensitivity curve of anomalous color among the three primary colors of a person having anomalous color vision marks its maximum value is corrected so as to enlarge the difference from wavelength where a spectral sensitivity curve of color adjoining thereto marks its maximum valueby setting the transmittance around the wavelength where the spectral sensitivity curve of the color adjoining to the spectral sensitivity curve of the anomalous color marks its maximum value below 50% and by setting the transmittance around the wavelength where the spectral sensitivity curve of the anomalous color marks its maximum value as high as possible.
