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.

Great, love them Was suggested these glasses by a friend when I said I needed a new pair of glasses for work but was struggling to find a good pair. Delivery was prompt and the cost was appropriate, a little pricey but worth spending money on a decent product. I initially wasn't going to post a review but was surprised to see the negative ones on here so thought to add my experience

Before you think about buying these… Before you think about buying these glasses, watch the videos on them as being a scam on youtube, they prove beyond a doubt that it is a scam! If you buy these you will be throwing your money away.

There support team is not up to the task of dealing with customers. There glasses are promising, but o dear, there customer service is not up to the task of handeling support request. I think they have just a few people on straf. I requested a return, they came back to me with the promise to send me a return label within 48 hours, 6 days later, no return label. I mailed them many times requesting an explanation of the delay, but did not receive any response whatsoever. I'm sure they're not willingly defrauding people, but if you wanne do business, your customer care team need to be up to the task. It makes or breaks your reputation, and if you ask me, they are breaking there's. I'm gonna file a claim with Paypal to get my money back. What a shame it has to go that way. I liked to order the correct glasses for my eyes, but oh dear, that's not gonna happen.

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.
