Wondering if you perceive color “normally’?
There are three main kinds of color deficiency, based on photopigment defects in the three different kinds of cones that respond to blue, green, and red light.Red-green color blindness is the most common, followed by blue-yellow color blindness. A complete absence of color vision —total color blindness – is rare.

OPTICS ENGINEERED FOR
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.
HOW THE EYE SEES COLOR
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.
WHAT IS 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.

ADDRESSING THE PROBLEM
WILL IT WORK FOR ME?
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.
