Are you a Protan? The Outdoor Protan Lens is For You

Protan, which is about 25% of red-green color blindness cases, results in more issues with reds than greens. So, we boost reds and normalize the red-green ratio.

Testimonials

Robert B.

The Best

"I have many premium sunglasses from Ray Ban, Persol, Randolph, etc. and the EnChroma are the best. Superior clarity, quality construction and I can see reds and greens much better. They make it a beautiful world."

Nicholas P.

The gift of color.

"I feel the gift of color is wasted on many. They don't appreciate the vibrancy of the world they have. I've had a taste of that world now. The immersive depth of colors touches my soul with joy."

Brian A.

Perfection

"I used to think color would never impact my life. These are amazing and changed, literally, the way I view the world. Thank you."
