What are color-blind glasses
Colour blindness (colour vision deficiency, or CVD) affects approximately 1 in 12 men (8%) and 1 in 200 women in the world. In South Africa this means that there are approximately 2.7 million colour blind people (about 4.5% of the entire population), most of whom are male.
Red and green color blindness are 99% of most color blind types.which is inherited by genes, but there is a characteristic that fathers pass on to their daughters that is invisible, while daughters pass on to their sons that is dominant color blindness. There is no cure for color blindness in newly developed glasses, which filter the light entering the eye and help the sufferer distinguish colors.
Generally speaking, color blind glasses are only suitable for red and green color blindness. After wearing the glasses, you can see the shape of the test map, which can help patients improve their ability to distinguish colors. Wearing color blind glasses can make the original blurred color blindness clearly identified, so as to help patients correct the disorder of color vision. If patients are troubled by color blindness, they can put into normal life through color blind glasses, which generally will not affect our daily life.
Congenital color blindness is caused by genetic problems, it is impossible to completely treat congenital, color blind glasses can help patients, some patients are not completely color blind but mild color blindness, so color blind glasses can play a relief effect, for color blind patients, this is a good news.
As far as current technology is concerned, there is no effective treatment for color blindness. Color blindness glasses are specially coated on the lens, so they can transmit the effect of long wave and reflect the effect of short wave. Generally speaking, color blind glasses are more suitable for patients with red and green problems. After wearing them, patients can see the shape of the test map, so as to improve their color discrimination ability.
