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.

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.

They seem to work perfectly! Thank you

Loved them! My boyfriend was so happy!

My very good friend was disappointed when a cheap pair of color-corrective glasses he purchased did not work. I immediately ordered these for him. He is red/green color deficient. As soon as he put these on and went outside, he stared at a car parked on the street for almost an hour because he said he had never seen the color red like that before! It made me so happy to know these allowed a person who has gone 36 years without seeing certain shades to see them for the first time. It was amazing to witness, thank you!

I will also add that they were shipped extremely quickly, seem to be quite durable, and are stylish as well. Also note I bought a refurbished pair and they looked brand new! I would highly recommend
