Purchased the glasses and didn't feel… Purchased the glasses and didn't feel they made enought difference to justify the cost. Got a return label after only two emails (!) Returned and have DPD confirmation of delivery. No refund. Six emails and three calls (unanswered) later, still no refund. Now have to go through the hassle of making a claim via my credit card provider. Do not trust them!

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

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.
