Color blindness and color vision have an impact on our lives. And it also causes some limitations to our choice of work. So do we generally wear color blindness corrective glasses or not? First of all, we need to understand what is color blindness? Color blindness can be divided into three categories According to the doctrine of the three primary colors, any color in the spectrum can be composed of red, green and blue. What is color blindness? Color blindness is a congenital color vision disorder. There are several types of color vision disorders, the most common being red-green color blindness. It generally refers to the inability to clearly distinguish colors, while colorblindness has a low ability to distinguish colors, usually although it can see the colors that normal people see. Generally speaking, both color blindness and color deficiency are congenital disorders, and, generally, there are more male patients than female patients. 1.Patients with total color blindness are considered normal if they can recognize the three primary colors, while those who cannot recognize all three primary colors are called total color blindness. 2.Patients with color blindness The ability to recognize any one color is reduced is called color blindness, mainly red weakness and green weakness. 3.Dichromatopsia (red-green color blindness) Patients who cannot recognize one primary color are called dichromatopsia, mainly red and green color blindness, and red-green color blindness is very common, because patients do not have normal color recognition ability since childhood, so it is not easy to be detected. In life, we can also use massage to relieve the symptoms of color blindness. You should eat more fruits and vegetables that are rich in lutein and vitamins. And actively engage in eye training. This is to stimulate the eye’s perception of color. Or you can correct your vision with color blindness correction glasses. What are color blindness correction glasses? Color-blindness corrective glasses are special glasses with lenses that transmit long waves and reflect short waves, so that colors can be recognized correctly. And nowadays, color blindness glasses are divided into contact lenses and frames, just like our normal myopia glasses. Therefore, color blindness corrective glasses are useful. The color blindness correction glasses are based on the complementary color antagonism and special coating on the lens to produce the effect of cut-off wavelength, which can be transmitted for long wavelengths and reflected for short wavelengths. Wearing color-blind glasses can make the original color-blind picture book illegible to be able to correctly identify. The effect of correcting color vision is achieved. Color blindness correction glasses can effectively fly down the interference of abnormal color light, improve the color vision of red-green color blindness patients, improve the ability to distinguish hue, so that color blindness patients can see the colorful world, free to carry out their favorite activities, and safe to drive vehicles. After wearing the device, the brain analyzes and compares the color difference between the two eyes, and achieves the purpose of distinguishing red and green colors. Easy to use, excellent results. According to the color blindness correction theory resin color blindness lenses can correct color vision abnormalities. Contact lenses for color blindness can effectively improve the color vision of patients and improve color discrimination. The lens is placed on the patient’s primary eye, and the brain analyzes the color difference between the two eyes to distinguish red and green colors. It is also suitable for people who have both color blindness and myopia. What can be done to prevent color blindness? 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, and taking measures to reduce the birth rate of color blind offspring is an effective means of prevention. In addition, we should be careful not to use our eyes for long periods of time, and not to drive or engage in color-sensitive work if our ability to distinguish colors is weak. Eat more fruits and vegetables rich in vitamins and lutein. Try to avoid strong light exposure to the eyes.
