Principle of Color Blindness Correction Glasses: According to the principle of complementary color topology, a special coating is made on the lens to produce the cut-off wavelength, which can be transmitted to the long wavelength and reflected to the short wavelength. Wearing glasses of color blindness can turn the original color blindness picture into a correct identification. To correct the effect of color vision disorders. Color blindness correction lenses are made of glass lenses or CR-39 superhard resin lenses, which are processed through many processes. They are mainly used for color vision correction in patients with congenital color vision abnormalities to achieve normal visual effects.
