What are color blind contact lenses
Color-blind contact lenses are made of non-ionic materials, which are relatively hard to absorb proteins and other precipitates, and the dyes used are very safe. The methods of wearing, removing and cleaning care for color-blind contact lenses are basically the same as those for ordinary contact lenses. However, attention should be paid to the fact that the lenses of color-blind contact lenses can not be cleaned with hot water or alcohol, nor can they be treated with hydrogen peroxide and enzyme tablets, otherwise the lenses may be oxidized and the correction effect may be affected.
- To improve the color vision of patients with red and green color blindness, improve the ability of color resolution, so that patients with color blindness can see a colorful world.
- Anti-ultraviolet and computer radiation, color blind contact lenses in addition to correct color blindness, but also with anti-ultraviolet and electromagnetic wave functions, suitable for use in different occasions.
- The lens is made of non-ionic material, which is not easy to absorb protein precipitation, and is clear and comfortable to wear.
Matters needing attention
The operation and care of color-blind contact lenses are basically the same as that of ordinary contact lenses. However, the lenses should not be cleaned with organic solvents such as hot water or alcohol, and the lenses should not be treated with hydrogen peroxide and enzyme tablets to prevent the oxidation of the lenses from antagonizing the color light and reducing the color discrimination ability.
The center of color blind contact lenses is light red. After wearing, most patients may have a dim vision, slightly wearing light red feeling, but it does not affect work and life. The reddish lens is neutralized with the color of the iris, so it does not affect the patient’s aesthetics.
Color blind stealth usually has two kinds of flat light and wearing myopia degree, which can not only improve color discrimination ability, but also special preparation according to the patient’s refractive error degree.
Do the color blind contacts lenses works?
Can patients be cured of color blindness after wearing red and green color blindness?
The answer is no. First, make a distinction between “correction” and “cure”, which are two different concepts. Color blindness is caused by genetic defects. Currently, medical science and technology have no way to solve and cure color blindness. Red and green color blindness films can enable patients to see the colorful world clearly. By wearing color blindness correction glasses, patients’ ability to distinguish colors will be greatly improved over time, even if the glasses are removed.
Should glasses of color blind correction wear all days?
The answer is no, don’t need to be worn around the clock, patients at the time of training to distinguish between colors and color to wear, but we suggest that patients should stick to wear for half an hour every day or so, to help set up the correct concept of color, to achieve the purpose of correction, we don’t want to bought for color blindness patients after corrective glasses only in wearing a “critical moment”, Because this does not help patients improve their color vision, it also violates the original intention of the patients to buy these glasses.
The red that how I see, green and normal person see, green still have some difference?
Actually people to feel the color is a kind of psychological process, a normal person to a feeling of color is not same, feel unable to quantify, people perceive color starts from the birth, the color of the color is unusual to see is not the same as normal person certainly, wear a color-blind after corrective glasses can see the color is to learn, slowly to reach the level of normal people.
Does the degree of abnormal color vision increase with age?
Human cones are also constantly metabolizing, and their functions will weaken with age. Just like human eyes, vision will decline in older people, and the degree of color vision abnormalities in patients will deepen with age, which also determines that color vision abnormalities should be detected and corrected as soon as possible.
what are benefits of color blind contact lens
Color blindness contact lens in the optical aspect to solve the pain of color blindness patients. The success of its development has brought good news to more than 200 million patients with color blindness and color deficiency in the world, enabling them to gain equal rights in life, study and work with normal people, and filling the gap in the field of optometry in the world.
