During the production of surgical glasses designed to protect the doctor’s eyes from laser scalpel radiation during surgery, one of the employees looked through the lenses. He could not fully distinguish colors, but found that the color sensitivity of the eyes improved.
Lenses from layers concentrate the basic principle of action. Each layer has a special coating and is a filter that blocks part of the visible spectrum. Glasses miss basic colors, enhancing the contrast properties of each under natural light.
Color blindness can either live with a person from birth, or manifest during life. Lenses against color blindness correct vision with protanomaly and deuteranomaly, when there is a violation of the perception of red and green. At the same time, the ability to partially distinguish shades is preserved.
The most serious violations cannot be corrected:
- Monochromatopsia. Develops with absolute color immunity.
- Dischromatopsia. People are not able to distinguish any primary color.
- Tritanomaly. With this pathology, the yellow and blue part of the spectrum suffers.
- Hemeralopia – night blindness.
In addition, in some cases of acquired color blindness, vision correction is not treatable. For example, if the retina of the eye or the optic nerve is damaged, then it is not possible to correct the perception with the help of external devices.
Indications for the use of color blind glasses
At the end of the 19th century, John Dalton in the process of research discovered a hereditary disease – color blindness. The scientist’s family, like himself, could not distinguish colors. Mostly this disease affects males, as the disease is transmitted through the X chromosome as a recessive trait.
Identified types of color blindness:
- monochromasia – a complete lack of ability to distinguish colors;
- protanopia – a person does not distinguish red shades;
- deuteranopia – the perception of the green part of the spectrum suffers;
- tritanopia is a defect in blue and purple.
Glasses that are similar in properties to sunscreens helped to overcome color blindness. A person who is not color blind will not see a significant difference. However, innovative technology has helped people with pathology see the world as it really is.
There are no contraindications to the use of glasses.
How to choose optics color blind?
The leading position in the market is held by EnChroma, which produces two types of color blind products in the USA:
- EnChroma Cx-D for persons with protanomal visual impairment.
- EnChroma Cx-PT for deuteranomaly.
Competition among US manufacturers is Oxy-Iso. Both companies offer a universal frame for all consumers. It is important to remember that the main part is lenses that correct vision. For glasses against color blindness, you can choose the right frame depending on your life or profession.
It is possible to order lenses or a whole product both from the manufacturer and in the online store:
- The average price of an adult model of the manufacturer EnChroma is 30 000 rubles.
- Children’s glasses from color blind EnChroma cost 20 000 rubles.
- Adding diopter to glasses increases the price to 40 000 rubles.
- The budget option offers Oxy-Iso, the official price is 18 000 rubles.
Colorblind goggles are produced by a leading manufacturer as an individual order.
However, picking up glasses for color blindness is possible only after an individual examination. The ophthalmologist must conduct a computer diagnosis of vision, as well as calculate all the necessary parameters.
After conducting research, a color blind patient should visit an official representative. The only company in the Russian Federation is OptikPro. This is necessary in order to choose the most suitable lenses that will create the desired effect, as well as get a guarantee for the purchase of products.

EnChroma talks about its products. The video allows you to understand a person with color blindness and projects lively emotions after using special lenses.
There are glasses that can help people with the most common types of color blindness (protanomaly and deuteranomaly). Production has entered the market, and glasses can be purchased from an authorized representative. However, at this stage, the development of models does not stop, testing of new lenses for people with rare types of color blindness continues.
