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 colour.

"I feel the gift of colour 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 colours touches my soul with joy."

Brian A.


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

    Love them

    I bought them for my husband because he's red green color blind. From what I read these glasses are perfect for him. It took about 10 minutes for him to see a difference. Now he's obsessed with them. He doesn't want to take them off. We're getting him the indoor glasses next but with a prescription so he never has to take them off. ♥️♥️

    Best birthday gift ever

    My son turn 23 on April 23rd, 2020 and I gave him a pair of Ellis outdoor sunglasses as a gift. He loved the style and the fact that he could see the colors for the first time. It was an amazing moment to see he is enjoying the beauty of the colors and the nature.

    Thanks to the technology in your glasses now people like him can see stuff they never would be able to see before. 🙏❤

    Enchroma glasses after week

    After I put them on first time I actually didn't see any difference, but I'm wearing them constanctly, because it says that I need to wear them for about 3 week to get maximum effect. So I'm still wearing them and hopefully could give better review to them after that time.

    For now I would say that the green color of trees and grass are more vibrant and contrast, also at some places where I don't see red at all without glasses, I started to notice the red color with glasses. But for now there is one downside of these glasses (maybe it will go away after some time, not sure) - it feels like the glasses put a red filter on top of your vision and sometimes I see white color as more like a pink.

    Also I remember when passing the enchroma colorblindness test, I was getting the moderate and strong protan results, most of the time moderate, but still would be getting strong constantly. And I'm thinking that maybe "sunglasses SP" would be better choice for me if these won't work.

    Red tint, green after.

    Loved the first pair from five years ago. This pair gives red tint. Company said it would go away inside two weeks and that they manufacture them differently now. But it's been a couple of months or so with no change. When I remove them. Everything is green for about 30 minutes. So a little strange, but not prohibitive. When i where them, vision is sharper and wow, who knew red was such a beautiful color? Would buy another pair again. I like the new colors i can see.
