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.

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.

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.

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.
