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 additonal fee. You can find more info on each frame's detail description page. Prescription EnChroma's are also available through an Authorized 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 color.
"I feel the gift of color 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 colors touches my soul with joy."
Brian A.
