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.

Excellent service + product I've been wholly enjoying my Protan Oakvales since buying them.. I think it's important to understand that these products are all off-the-shelf rather than personally customised; thus, whilst designed to work best for as many people as possible, they may not be perfect for everyone. I must admit I didn't really see anything 'jump out' at me the moment I tried my glasses on the first time or have that elation of sudden revelation, but after wearing them for extended periods, it's actually when I take them off that I realise just what I'm missing out on. There are colours in so many things I never thought were present, but are... and nature is certainly way more exciting to look at. They certainly add joy to being outdoors and they improve my quality of life by unveiling parts of the visual light spectrum that I would otherwise have trouble with, even if they're not 'tuned' to my unique colourblindness. Really looking forward to using them as much as I can this upcoming summer. Also, big shoutout to Helena on the customer support team for helping me out when I damaged my first pair. greatly appreciated :-)

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.

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.

Customer service non existent Customer service non existent. Unreachable when the return of the product was requested. Have sent 5 emails and phoned several times without an acknowledgement of the emails and just get voicemail on the phones. Have emailed both their UK and US "support" addresses.
