I bought these for my 15 year old son. He’s always had trouble with blues and purples, and as he’s studying art, it’s starting to prove a bit of a problem. After watching some YouTube videos and doing a lot of reading, I thought I’d give these a try. And thank god I did !!! THEY REALY DO WORK! Yes they are expensive (even more so when you have to pay 20%import duty to the UK), but what price can you put on seeing colour? Just seeing the absolute amazement on my sons face when he first put them on honestly made me cry. The shocked look on his face as he screamed around the house doing double takes on things and saying “How long has that been blue”? Or “That’s purple”! was one of the best moments of my life. It’s not very often you have the chance to see pure joy and wonder, but this was one of them.
They aren’t a magical cure (shades of certain colours are still a problem), but they come damn close and are well worth the money.
And if a 15 year old can wear them in school, yes, they ARE COOL.

Strong Protan.

Superb, I have been visiting a hotel in Florida and didn't know it was pink! Did the eye test on line, Also prescription readers good.An optician in UK was sceptical but I have been amazed at their effect.


Awesome glasses, loved the price.

Great glasses, great experience, strong case!

Purchased these as a protanope, after checking out the various alternatives online and saw that Enchroma was highly recommended by color vision resource groups. I'm very happy with the lenses, they are lightweight and have really helped colors *pop*! The glasses can't magically fix my cones, but they definitely have enabled me to really distinguish between colors.

The case they come in is especially tough, but I'll soon be contacting Enchroma for a replacement. I had placed the glasses in the case they came in when going to bed, and my 4-month old puppy (still teething!) got ahold of them and Went. To. Town. The case fully protected my glasses, and are still able to function as a case but are definitely worse for wear... so consider this a glowing review of the sturdiness of the case! I'd rather get another Enchroma case than buy some generic one.

Jenny, we're so glad to hear that you are loving your glasses and we're even happier to hear that your case kept them safe from your mighty pup! If you could, please send us an email at Support@enchroma.com and our support team will be able to help you out with a new case!
I bought them for my son. He loved them. His colors got better the more he wore them. He says the...
