Green blindness, also known as second color blindness, occurs when a person cannot distinguish light green from dark red, purple from cyan blue, or fuchsia from gray, and sees green as gray or dark black. Green blindness is a genetic disorder that is caused by the X chromosome on the chromosome and is often accompanied by symptoms such as the inability to distinguish red from red-green. The corresponding lesion organ where green blindness occurs is the eye, in more detail the retina, and in further detail the optic cone cells. Prevention: Since color blindness and color deficiency are hereditary diseases that can be passed on to offspring, avoiding marriage between close relatives and investigating each other’s family history of hereditary diseases before marriage, as well as taking measures to reduce the birth rate of color blind offspring, is an effective means of prevention. Solution: Color blindness correction lenses are an effective way to correct color blindness. The principle of color-blindness correction lenses is based on complementary color antagonism, which is a special coating on the lens that produces a wavelength cut-off effect, transmitting long wavelengths and reflecting short wavelengths. By wearing color-blind glasses, the original color-blind chart that was not recognizable can be correctly recognized. The effect of correcting color vision is achieved. Color blindness correction lenses are designed and developed according to the theory of color blindness correction. There are two types of lenses, contact lenses and wide frames, both of which are effective in correcting red-green color blindness. Contact color blindness glasses because of its better privacy, can well protect the privacy of consumers, suitable for medical examination and usually wear; frame type because of its lens surface special red coloring, product appearance is more obvious, for the usual work or driving driving wear relatively convenient; two characteristics only for consumer reference and their own choice.
