EnChroma Color Blindness Test: Instructions

This test measures the type and extent of color blindness.

This test is for personal informational purposes only and is not a qualified medical diagnosis. Results may vary depending on type and quality of your display device. Do not wear any type of filtering eyewear for this test: doing so will invalidate the result. Please consult an eye care professional for more information regarding color vision deficiency.

EnChroma Cx: Color Blindness Correcting Glasses

The EnChroma Cx uses high-tech optics to enhance color before it reaches the eye, giving the color blind access to a new world of color experience.

Red-green color blindness is a genetic condition where the light-sensing function of the red and green cones is more overlapping than normal. By filtering a narrow region of the spectrum where overlap is occurring, the normal separation can be restored. For many people with color blindness, the effect is a profound emotional experience.

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.
