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.

The company's terrible pricing policy The company's terrible pricing policy. 10 months ago I flew to Kuala Lumpur and bought glasses for $300. Today I flew to the city on business and decided to update the lenses, as there were scratches on them. Lens replacement costs $290. Are you serious??? Allegedly, they will be specially cut out for my frame. If I had known about their policy, I would not have bought these glasses a year ago. In fact, they don't change color much. If you want to but haven't bought it yet, it's better not to buy it. I don't understand their attitude to their clients. Instead of selling new glasses to your loyal audience in such an ugly way, it's better to give them privileges and we will be your ambassadors

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.

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.

Really bad customer support and returns Some of the worst customer support I've ever encountered - I've known my entire life I'm red weak, all red colours are really dark. Finally decided to try glasses and the Enchroma test said I was Deutranope (Green weak). These days the test says strong Protanope (Red weak), guess they fixed it. Not an expert so no way I could know they're different without a long search. I ordered the recommended Green weak glasses, they did nothing, looked up the terminology and decided to try for replacements as the test had made a mistake. Their customer support blocked me at every stage, took vast amounts of time to answer queries, stalled and told me it would cost more to return them than I'd paid for them (in the UK). This was in 2020 - but I tried talking to them again a few years later after Covid and got an equally bad response. The stupidly expensive glasses are sitting on a shelf unused. Maybe their Protanope glasses work great? But their customer support will avoid any kind of refund or exchange at all costs! Date was before earliest date I could enter on the site.
