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.

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.

$400 glasses not delivered bad customer support! I bought a pair of colour blind correcting glasses which did not get delivered. When I raised this with their customer service team they informed me that UPS had contacted me for additional payment and I told UPS that I wanted my $400 glasses destroyed. I have asked for more details and their customer service team have not answered any of my emails.

These glasses are frickin awesome These glasses are frickin awesome! I don't know if my vision with them is the same as what a normal person has. But one thing will never be the same. They've been seeing colors all their life, so for them, what's the big deal. But I got my color vision at age 65. I will never cease to be awe-struck by the green of the trees, the reds, oranges and purples of flowers, the sunrises and sunsets. It's truley amazing.

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.
