How EnChroma Glasses Work

What goes into developing the incredible EnChroma lens that gives color blind people the ability to see colors they only previously imagined? Let’s start with a little background on how we process color vision in the eye.

Normal color vision occurs when white light, which contains within it all the colors of the rainbow, enters the eye. This light activates three kinds of photopigments, one in each of the three photoreceptors sensitive to different parts of the visible spectrum: blue, green and red.

Most types of color blindness occur when the eye’s green and red color sensitivities shift, resulting in too much of an overlap. This excessive overlap causes distinct hues to become indistinguishable. As a result, the number of shades of color a typical color blind person can see may be reduced by as much as 90%.

EnChroma developed optical lens technology that selectively filters out wavelengths of light at the precise point where this confusion or excessive overlap of color sensitivity occurs. This increases contrast between the red and green color signals, alleviating symptoms of color blindness for a richer experience of the world. With the application of science, optics, mathematics and more than 10 years of clinical research, EnChroma continues to advance the field of color vision research and bring new products to market that solve unique color deficiency issues.

...when someone with red-green color blindness wears a pair of EnChroma glasses, they perceive a more accurate range of colors - and the experience can be life changing.

Will EnChroma Color Blind Glasses Work for Me?

Color blindness is not a singular condition. It encompasses a range of conditions, from mild to severe, that can cause each person to see color differently. EnChroma glasses are designed to improve color vision of people with forms of anomalous trichromacy, which are estimated to comprise four out of five cases of color blindness. The most common types are Protanomaly and Deuteranomaly, which are forms of partial red-green color blindness. In the most extreme cases, the complete absence of one of the cone photopigments, called Protanopia or Deuteranopia, are considered dichromats who may see limited results due to the complete inability to see red and green color differences. Fortunately, most cases of color blindness respond well to EnChroma spectral lens technology, enabling the perception of bright, vibrant color. Learn more about types of color blindness.

Our outdoor lenses in bright sunlight are designed to provide the maximum color impact. See our Lens Guide for more details.

To find out if you are color blind--and what type and severity of color vision deficiency--take our brief EnChroma Color Blindness Test. You can also consult with a qualified eye care professional and try EnChroma glasses at one of our Authorized Retail Locations.
