Whether you’re in the great outdoors or just out and about, you can experience deeper, richer and more vibrant colors in everything from a sunset or vista to outdoor sports and entertainment. Our lens technology works for about 80% of those with red-green color blindness.

NEW! EnChroma's Next Generation Lens Technology

Our new lens design has up to 35% better color performance over previous design, renders whites and neutrals more accurately, and stimulates your brain’s color vision processing.

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.

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.


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

    Coolest gift

    I bought two pairs of glasses for my 13 year old nephew (indoor and outdoor). We recently found out he was colorblind. He had no idea as he had learned his colors fine. What he learned was just different because that was all he had ever know. What he saw vs normal color scale was blues, yellows and variant shades of grayscale and brown. These glasses are amazing and wonderful. His world has been turned upside down in a wonderful way. He loves to flip his glasses up and down to look at the difference in color. He LOVES the new world of color and has told me that it is depressing when he does not have his glasses on. He has commented on how bright everything is over and over and has been emotional as he has expressed his gratitude of this gift. He loves looking at the different colors of skin tone, lipstick and berries. It is one of the coolest gifts I have ever had the privilege of giving. Thank you EnChroma for a wonderful product.

    So hopeful!

    I wish I could say these were everything I’d hoped they were, but unfortunately they were not. When my husband first out them on, I was so, so excited for his reaction. But they did nothing for him. I had him follow the instructions as to how much he should be wearing them, but still nothing. More sad than anything that these didn’t work for him.

    Hi Ashlie,

    We're sorry the glasses did not work for your husband. It sounds like you ensured he got the right lens type for his CVD and had him wear them for an extended period. If he has taken our test both with and without wearing the glasses and scored a zero on his green cone both times, it is possible he is a dichromat for whom the glasses can't work. Either way, you can visit to start the return and refund process.

    As soon as I put them on I saw colours that have eluded me my whole life. The colour Red is my achilles heel and it jumped right out at me, I should have gotten these glasses years ago! Love them!!

    Effective - worried about heat impacts

    These glasses make the world a colorful place to be. I used to think pumpkins came in 1-2 versions of orange. Truth is AT LEAST 7!!

    My first pair had an issue with getting hot and the finish wearing unevenly. The ENCHROMA TEAM provided very good customer service to help me find a solution!

    Thank you all.
