Part optics, part neuroscience, EnChroma® glasses unlock a new world of color for people with color blindness. Our glasses are designed to make you look good, too, so better color vision can be a seamless part of your everyday routine.
The EnChroma lens technology is based on over a decade of research effort to understand the causes of color blindness and how to engineer an optical technology platform to address the problem.
The structure of the eye projects light and images onto the retina, where a dense matrix of approximately 6 million retinal cone cells turn that picture into neural signals transmitted up to the visual cortex. Each cell is ‘color specific,’ responding mainly to light of specific frequencies. The three different types of cone cells correspond to the three primary colors of light: red, green and blue.
The eye responds to light, but vision is formed in the brain. The visual cortex must process a vast amount of information to decipher where objects appear and their properties such as motion, shape and color. The ability to see color is an important part of being able to see objects in situations where they are not clearly set apart from the background, such as oranges in a tree. In modern life we are also faced with the need to interpret color-coded information such as signs and lights. These are just a couple of examples of how color vision helps us to see and understand the world.
Approximately 1 in 12 men and 1 in 200 women have some degree of color blindness. There are different types of color blindness but the most common is known as ‘red-green color blindness.’
Color blindness (also called color vision deficiency by vision scientists), is a condition in which the retinal cone cells respond to light differently than normal. People with color blindness can usually still see colors but have color confusions or see certain pairs of colors so similarly that they cannot tell them apart.
The underlying cause of most color vision deficiencies is due to the red and green-sensitive retinal cone cells having an overlapping response to light. Instead of responding separately to each wavelength of light, their response is highly similar. To compensate for the overlap, the EnChroma lens contains proprietary optical materials that selectively remove particular wavelengths of light exactly where the overlap is occurring.
According to genetic population statistics it is estimated that 4 out of 5 cases are forms of partial color blindness (also called anomalous trichromacy) which are addressable using the EnChroma optical lens technology.
To find out if EnChroma glasses can help with your color vision deficiency, take our online Color Blindness Test and receive a personal assessment, or visit one of our Authorized Retail Locations to consult with a qualified eye care professional.
