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.

- AMAshley M.Verified BuyerRated 5 out of 5 stars4 years agoReally Works!
I bought these for my husbands birthday and he was absolutely speechless when he finally saw red and green colors! He never wants to take them off. Thank you Enchroma for making such a special gift!
- CHCarl H.Verified BuyerRated 5 out of 5 stars1 year agoMild protan works for me
Love the style and they do definitely work!
- DSDave S.Verified BuyerRated 5 out of 5 stars1 year agoSurprised
I have worn the Northside Cx3 glasses for a week now. The first two days were strange. I saw Colors I had not seen. In particular, red and orange jumped out...almost to the point of being distracting. I have adjusted to that now and the world is so much more colorful and clear than before. Someone asked me what it is like and the best example I can offer is consider viewing everything through a very dirty window versus opening the window and looking. Excellent. I would not hesitate to recommend these.
- KYKai Yip W.Verified BuyerRated 4 out of 5 stars2 years agoThe sun glasses looks awesome. Fit well. Shipped successfully to australia
The quality of the glasses is great. The prescription is done precisely. Wish there is an indoor glasses with the same specifications (length, width,etc). The only thing that disappoint me is the sunglasses case does not fit to sun glasses. Doesn’t look like they check if the case fits with the sun glasses. Otherwise everything is great. Will recommend to others
