Eyeglass lenses for correcting color vision
摘要:
An inexpensive, high-performance, color vision correcting plastic eyeglass lens comprises a partial reflection film for partially reflecting light, or a coloring agent for partially absorbing light, or a combination thereof, so that an intended color vision rectifying spectral characteristic curve can be established in or imparted to the lens.
