what is color blind glasses
Any color in nature can be synthesized by red, green and blue, and the color perception of human eyes is also synthesized by red, green and blue. When abnormal cones occur, symptoms of color blindness such as red, green and blue blindness occur.
If the function of two types of cones in the retina is low, and the signal of two of the three primary colors is low (commonly known as dichromatic weakness) and the other primary color is increased, the patient has abnormal color vision, which is called type A color blindness.
If one type of cone cell in the retina is poorly functioning (commonly known as chromatism) and the other two are enlarged, the patient’s three primary colors are out of sync, which is called type B color blindness.
Color blind glasses are based on complementary color antagonism, special coating on the lens, the excessive light into the eye reflected through the glasses, the weak light into the eye increased, so that the proportion of the three primary colors into the human eye tends to be normal, and finally achieve the correct color discrimination.
Correction lenses for color blindness are now have contact lens and frame glasses.
Suggestion for using color blind glasses
1. Use color blind glasses should start with children.
Color discrimination is cultivated from an early age. If color-blind children can wear color-blind glasses from an early age and have the opportunity to correctly identify colors from an early age, it is beneficial for them to develop their color discrimination ability when they grow up.
In addition, if they are exposed to colors from an early age, their color discrimination ability will be greatly enhanced through memory over time.
2. Color blind patients with weak vision should also wear color blind glasses.
Color blindness is not necessarily associated with good or bad vision, but some color blindness patients with poor vision, both color blindness and myopia or farsightedness, then there are a variety of options for correcting color blindness:
1) Color blind glasses with visual correction can be worn
2) Wear a normal pair of corrective eyeglasses, and then put a flat color blind lens on the outside of the glasses
3) First get a pair of contact lenses with corrective vision, and then wear a pair of flat color blind glasses
Of course, among the above methods, the color blind lens combined with the visual correction and color blindness correction function is the most simple and convenient.
3.Mutiple function in one glasses.
In addition to correcting color blindness, colour blind glasses also have the function of anti-ultraviolet and electromagnetic waves, looking like light sunglasses, therefore, color blind glasses can be used in different occasions, play a mirror multi-purpose function, both correct colour-blindness and anti-ultraviolet and computer radiation.check our TPG-038 colorblind gnasses.

Color blindness is divided into congenital color blindness and acquired color blindness, acquired color blindness due to disease, disease will be better.
Congenital color blindness is inherited and cannot be treated.
There are two types of congenital color blindness: complete and incomplete color blindness.
Patients with complete colour blindness lose all the color sense function in the retina and can only distinguish black, white and gray colors, which cannot be corrected with colour blind glasses. Incomplete color blindness can be corrected by wearing colour blind glasses.
2.Color-blind glasses are versatile.
There are two types of color blindness, class A and class B.
The same type of colour blindness can be divided into different grades according to different degrees of severity. According to the experiment of colour blindness correction, the same type of color blindness patients with different grades need to wear different grades of corrective glasses, otherwise the effect is not good.

Why the glasses is not works for me?
For a number of patients with ineffective correction of color vision disorders, consider whether the following factors are related
1) The discomfort of dim and reddish objects when wearing color blind glasses at the beginning;
2) Slight color weakness;
3) Due to the deficiency of contact lenses for colour-blindness, the spectral antagonism generated by them is inappropriate
2. It is normal that the color vision acquired by patients with color blindness after correction may still be different to a certain extent from that obtained by completely normal people.
3. The wearing operation and nursing of color blind contact lenses are basically the same as those of ordinary contact lenses, but do not clean the lenses with organic solvents such as hot water or alcohol, nor treat the lenses with hydrogen peroxide and enzyme tablets to prevent lens oxidation from changing the antagonistic effect of color light and reducing the ability of color discrimination
4. The wearing of color blind glasses requires an adaptation period: The principle of color blind glasses determines that they will filter out part of the wavelength of light, so the brightness will be reduced, and patients may feel uncomfortable at the initial stage of wearing, which requires a certain adaptation period.
We recommand wearing for 1-3 weeks for better correct color vision.
