Do you have color-blind glasses?

With the development of science and technology, color-blind glasses appear on the market at present. According to the theory of complementary color antagonism, color-blind glasses are coated on glasses, so that long-wavelength light is transmitted and reflected by short-wavelength light, and the purpose of correcting abnormal color vision is achieved. Generally, colored contact lenses and colored frame glasses are used. Colored contact lenses are effective, suitable for patients with weak color and red-green color blindness, but not for color blindness. Because color blindness is caused by retinal cone cell malnutrition, it is caused by cone cell deficiency. The use of color-blind glasses needs to be diagnosed clearly through ophthalmological examination, and appropriate color-blind glasses should be selected according to the condition, so as to correct color blindness. Color-blind glasses need to be specially made, and effective color-blind glasses should be selected according to the degree of color blindness of patients.

Using color-blind glasses is one of the most commonly used methods to adjust color blindness. There are two kinds of color-blind glasses, including contact lenses and ordinary glasses. The lenses of color-blind glasses are specially coated, which can cut off the wavelength, transmit the long wave and reflect the short wave. After wearing color-blind glasses, color-blind patients can distinguish color-blind pictures and correct color vision disorders.

How to adjust color blindness

Besides wearing color-blind glasses, acupoints and acupressure can also regulate color blindness. Acupoint massage two centimeters below the eyeball can improve eye function. When acupressure, the patient should exhale and press hard for six seconds. Patients can open their eyes or close their eyes to do acupressure, which can improve the ability of eyes to distinguish colors, and closing their eyes can improve the problem of abnormal vision. Finger pressure can be repeated, patients persist for a long time, and abnormal color vision can be slowly relieved.

Color blindness is not only congenital, but also secondary. If color blindness is caused by other eye diseases, the primary disease must be treated before color blindness can be controlled.

This paper introduces the function of color-blind glasses and the methods to adjust color blindness. Color blindness is a rare disease, which is determined by genetic factors and therefore cannot be cured. Although color-blind patients can't distinguish certain colors, their lives will not be greatly affected. If color blindness is accompanied by symptoms such as weak color, photophobia and nystagmus, it needs timely treatment and surgery if necessary. Patients with color blindness should pay more attention to protecting their eyes and eat more eye protection food.
