EnChroma glasses, a marriage of color vision science and optical technology.
The only specialty eyewear that alleviates red-green color blindness, enhancing colors without the compromise of color accuracy.
Color blindness (or color vision deficiency), is a condition where a person’s eyes are unable to see colors under normal light. People with color blindness have a hard time telling colors apart from each other.
HOW EYES SEE COLOR
The retina contains approximately 6 million retinal cone cells. 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: red, green and blue.
Color blindness affects millions of people worldwide. It affects 1 in 12 men and 1 in 200 women. The condition ranges from a variety of classes, red-green color blindness being the most common.
Most people who suffer from color blindness are not blind to color, but have a reduced ability to see them. Color blindness is also called Color Vision Deficiency (CVD).
CVD can be acquired, but most are inherited genetically. The genes that influence the colors inside the eyes, called ‘photopigments,’ are carried on the X chromosome. If these genes are abnormal or damaged, color blindness occurs.

A person with red-green color blindness sees the world differently. Their red and green photopigments have more overlap than normal, making them unable to see certain colors. EnChroma found a way to alleviate this by creating a specialized lens that filters out specific colors.
Creating the lens started out as computer simulations, constructing sophisticated models that simulated colors and the extent of color vision deficiency. To create this model, EnChroma utilized the latest research on the genetics of color blindness and various anomalies related to photopigments, and linked these into a model where it gives the effect on how people with red or green color blindness perceive colors.
The second step was to solve the problem by designing an optimal filter, targeting specific photopigments. EnChroma created a (patent pending) method called ‘multinotch’ filtering, cutting out sharp wavelengths of light to enhance specific colors. EnChroma lenses separates the overlapping red and green cones, helping improve vision for people who have difficulty seeing reds and greens.
