A part of optics, a part of neuroscience, EnChroma® glasses opened up a new color world to people with color blindness. As our glasses are designed to make you look better, better color vision can be a seamless part of your daily life.

EnChroma lens technology is based on over 10 years of research to understand the causes of color blindness and how to design the optical technology platform to solve the problem

Eyes respond to light, but they form vision in the brain. The visual cortex needs to process a large amount of information, decode where the object appears, and decode those characteristics such as movement, shape and color. The ability to see color is an important part of an object that looks like an orange in a tree, which can be seen unambiguously separated from the background. In modern life, it is necessary to interpret color-coded information such as signs and electric lights. These are just a few examples of how color vision helps understand the world.

About one tweenth of men and two percent of women have some degree of color vision abnormality. There are various kinds of color blindness, but the most common is "red and green blindness".

Color vision abnormality (also called vision by visual scientists) is a state where reaction of retinal pyramidal cells to light is unusual. People with color vision abnormality usually see color, but because color confusion and color combination are seen, it is not possible to separate colors.

The fundamental cause of most color vision abnormalities is due to the overlapping response of red and green sensitive retinal cone cells to the light. These reactions are very similar, not reacting independently to each wavelength of light. To compensate for overlap, the EnChroma lens contains proprietary optical material that selectively removes overlapping specific wavelengths of light.

According to the statistics of the gene population, 4 out of 5 cases are in the form of partial color vision abnormality (also known as abnormal trichromaticity) and can be dealt with using EnChroma optical lens technology.

To investigate whether EnChroma Glasses can help you solve your color blindness, get personal evaluation under our online color blind test or consult a licensed eye care professional Please visit one of our authorized retailers.
