FAQs
Have a question? We are here to help.
Should I get indoor or outdoor glasses? What's the difference?
Just like sunglasses, our Outdoor lenses are great in bright to partly cloudy sunlight and provide 100% UV blocking. Our indoor lenses have a light tint and work best in your home, office, at school, or in more cloudy, grey conditions. Both work well so its really a matter of personal preference.
Are your glasses available in prescription?
Yes. Most of our frames are available in either single vision or progressive prescription options for an additional fee. You can find more info on each frame's detail description page. Prescription EnChroma's are also available through an Authorised Retailer.
What's your return policy?
We offer a 60-day money back guarantee even on prescription glasses. This gives you plenty of time to adjust to our glasses. For more details on our policy click HERE.
Testimonials
Robert B.
The Best
"I have many premium sunglasses from Ray Ban, Persol, Randolph, etc. and the EnChroma are the best. Superior clarity, quality construction and I can see reds and greens much better. They make it a beautiful world."
Nicholas P.
The gift of colour.
"I feel the gift of colour is wasted on many. They don't appreciate the vibrancy of the world they have. I've had a taste of that world now. The immersive depth of colours touches my soul with joy."
Brian A.

Amazing. I have been colorblind my entire life so as soon as i put on the glasses i saw color. Best purchase i have ever made.

Last time I heard about the company they didn’t have anything for Strong Protan. Just by chance I looked again and there they were. I was so excited when I got the glasses that I went outside in the rain to have a look but nothing happened. A day later it was nice and sunny and I tried again. I’ve been in the US Navy 14 years and it was the first time I saw our flag look that amazing. I can’t believe what I’ve been missing!

To anyone considering buying these as a gift, make sure the recipient takes Enchroma's colorblind test, and keep in mind the glasses might not work. Bought these for my colorblind boyfriend with that mindset. He was skeptical at first as to whether they would work - only to go around gushing about how much he loved them for the following weekend to all his friends and relatives! The look on his face when he was able to differentiate certain colors for the first time was priceless. If EnChroma ends up making indoor glasses for my boyfriend's specific type of colorblindness, I will most certainly purchase them.
