  • PROPRIETARY SPECTRAL LENS TECHNOLOGY: Our award-winning lens technology is the result of more than a decade of pioneering research by EnChroma scientists, and is uniquely engineered to enhance color vision for people with color vision deficiency.
  • SCIENTIFICALLY FORMULATED AND DESIGNED IN BERKELEY, CA: EnChroma’s eyewear is made in our medical device manufacturing facility where EnChroma technicians perform 100% of lens machining, assembly, and quality verification using a combination of imported and US components.
  • BEST-IN-CLASS LENS MATERIAL: Our lens material is made with Trivex®, an optical-grade resin that delivers a best-in-class combination of impact protection, lightness, and clarity.
  • 100% UV PROTECTION: EnChroma lenses block 100% of the UVA and UVB radiation components in sunlight. According to the World Health Organization, UVA rays are unfiltered by the atmosphere and can cause the most damage to vision health.
  • ULTRA-TOUGH ANTI-SCRATCH COATING: To ensure a long service life free of scratches, our lenses are clad with an optically clear, thermal-crosslinked coating to provide added lens durability.
  • CLARITY ENHANCING ANTI-REFLECTIVE COATING: Lenses without anti-reflection coatings reflect up to 12% of light back into your eyes. EnChroma lenses feature dual-surface anti-reflective coatings to reduce reflections by more than 90%.
  • SUPERHYDROPHOBIC TOP COAT: This water repellent surface treatment makes the lens slippery so that dust and dirt can be easily removed with a quick wipe of the included microfiber cloth.
  • EXTRAS: Signature box, hard-case, EnChroma® cleaning cloth, microfiber carrying bag, user guide, and colorful balloons included.
  • WEAR PRESCRIPTION GLASSES? EnChroma lenses can be custom made for your prescription needs, including single vision and progressive correction. Or, try our Receptor Fitover to conveniently wear EnChroma glasses over your existing prescription eyewear.

Nice glasses! with this, i now can differentiate colours more frequently but need to relearn back the colours. The glasses came early than expected.

The Color of the world has changed!

I bought the Cx3 Sun glasses for my husband as our 4th anniversary gift. He can now smile broadly looking at the view around him. He loves the fact that red colour is so vibrant and attractive. But he could wear the glasses just about 10 minutes because he feela dizzy. Is it normal?

Christmas Miracle

I bought these glasses for my boyfriend of 6 years. I bought these just in time for Christmas, and may I say, their delivery was fantastic!! Anyways, I took my boyfriend to a nearby hill that overlooks the city on Christmas Eve. I decided to take him to this hill because a sunset is full of vibrant colors and overall is magical. My boyfriend is not an emotional guy whatsoever, and he is not as expressive as I am. Let me just say this, I have never in the 6 years that I’ve known him, see him tear up over a sunset!! It was the most sweetest moment ever. I am so glad that I decided to get him these for Christmas! At first I thought it was a bit pricey, but my goodness is it worth it after you experience your loved ones seeing colors they couldn’t before. Now, I think they’re a bit underpriced! I am so blessed for having team Enchroma on our side. We are definitely looking into buying indoor glasses now ! Thank you so much for all the hard work you put into this Enchroma.


A group of us gave these glasses as a gift to a schoolmate who is colour deficient and his reaction was priceless. He was utterly shocked by his gift and loves them very much. It is great that he was finally given the chance to see what we see and I am sure he appreciated them very much. Great Product!

I put the glasses on the first time and it was amazing. I can see colors perfectly and more vividly. I wish they had glasses for both outside and inside use. Maybe a future invention:). I highly recommend these glasses because they will totally change your life. IThank you EnChroma!
