EnChroma Cx

Color Blindness Correcting Lens

Made with Digital Color Boost™
Click here to learn how it works.

What is it: The EnChroma Cx is a sunglass lens for color blindness correction. It’s made with an extra-strength version of EnChroma’s proprietary Digital Color Boost™.

How it works: Red-green color blindness is a genetic defect that makes the sense of red and green “crossed” so they are more overlapping than normal. By removing the wavelengths of light where overlap is occurring, the lens amplifies the color signal sent to the brain.

What it does for you: Colors appear bright and pure, popping out to give a pronounced “3D effect”. Thousands more shades can be seen. Colors can be recognized more quickly and with less confusion. Traffic signals go from red, yellow, white to red, yellow, green. Road signs, red curbs and safety markings are more visible. For many people with color blindness, the effect is a profound emotional experience.

Fact: 1 in 12 men and 1 in 200 women worldwide have color blindness.

What People Are Saying

Then I put on the glasses. Unbelievable! Now I saw two entire additional color bands, above and below the yellow arc. It was suddenly a complete rainbow. I don’t mind admitting, I felt a surge of emotion. It was like a peek into a world I knew existed, but had never been allowed to see.

David Pogue, New York Times

This morning has been amazing and overwhelming. It hit its peak when I was able to look into my wife’s eyes and see the many shades of green and brown – something I cannot think about even now without getting emotional.
