Good but not as "wow" as thee videos show Strong Protan. Bought sunglasses. There is some improvement to the vision of reds. Although with some drawbacks: they kind of tint the rest of the colors. They only seem to work on reflected lights (on emitted lights, like the one of a screen doesn't seem to work). They must be used in open sun to see some effect. At the moment it's the best available option if you want to improve your color vision.

Quality of progressive Rx is the best, non-colorblind can use. Quality of the Rx is the best. I am not colorblind, but being a scientist, was curious & ordered non-Rx pair to test as sunglasses. I was pleased with the results so ordered sunglasses in my (progressive) Rx. Rx was large improvement over my clear pair, having wider vision, so later I ordered indoor Rx pair. Lenses increased contrast (in addition to color enhancement). in my opinion more non-colorblind should use these.

scam See on Youtube: "Exposing the Color Blind Glasses Scam" from "MegaLag" Channel This company is scamming people, see upper mentioned video for explanation

Amazing I can see more colors than I ever thought possible! My wife loves that I don't have to ask her what color things are all the time.

The company is a scam The company is a scam. I think preying upon incurable eye conditions and people desperation to see. Properly is disgusting. The slew of bogus reviews is disgusting, and the level of manipulation this company has gone to, to pull the will over your. Eyes is insane. Avoid this despicable company at all costs.
