COLOR VISION CORRECTION CONTACT LENS

摘要

PROBLEM TO BE SOLVED: To provide a color vision correction implement which makes color vision deficiency hardly identifiable. SOLUTION: The contact lens 10 is provided with a color vision correction section 20 having such color vision correction spectral characteristics as to approximate the respective stimulus value proportions of three kinds of the visual cone cells of the retina of a color vision deficient person to the respective stimulus value proportions of three kinds of the visual cone cells of a color vision normal person by converting these stimulus value proportions. This color vision correction section 20 is formed at such a size at which this section is confined within the iris.
