EnChroma uses a mathematical formula to directly communicate with the brain’s visual system. This system is calculated to help a color-blind person observe the correct ratios the brain needs for normal color vision. The company uses over 100 reflective coatings at different opacities rather than a single tinted lens.

The highlight came on Day 4 of my tests, when my kids discovered a rainbow arcing across the sky, pointing and exclaiming. I looked. With my own eyes, I could barely see it. Maybe there was a soft arc of yellow, but that was it.
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.
