The invention discloses a
color vision correcting lens,
color vision correcting equipment and a manufacturing method of the
color vision correcting lens. The color vision correcting lens comprises a lens body, wherein an all-
dielectric multilayer membrane pack with a selective spectrum transmission
cutting-off feature is deposited on the front side of the lens body, a visible-band
broadband antireflection
multilayer membrane pack is deposited at the back of the lens body, the transmission of the band of 545-555 nanometers is not larger than 1%, the transmission of the band of 435-450 nanometers is 15-25%, and the transmission of the band of 640-655 nanometers is 25-35%. The color vision correcting lens has the advantages that appropriate high-
refraction-index and low-
refraction-index membrane design is selected, transmission is allowed to be
cut off at specific bands while rest visible bands can transmit without obstruction, all environment representation information, brightness information and rich color information are obtained, the color vision
abnormality of
target groups is weakened greatly, and the quality and satisfaction of learning, work and life of the
target groups are increased; the color vision correcting lens is compact in structure, simple to manufacture, low in cost and convenient in large-scale production.
