What's Inside
  • 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: All EnChroma lenses are made from optical grade resins that deliver 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 any of our Fitovers to conveniently wear EnChroma glasses over your existing prescription eyewear.
  • WEAR CONTACTS? Our standard (non-prescription) eyewear can be combined with your existing contact lenses to deliver comprehensive color and clarity correction.
  • 100% SATISFACTION GUARANTEE: EnChroma backs up every purchase with our 60-Day Money Back Guarantee and 2-year Warranty See details.

WARNING: This product can expose you to chemicals including Nickel, which is known to the State of California to cause cancer. For more information go to

How does this warning relate to EnChroma glasses?

Like most eyewear frames, EnChroma frames may contain stainless steel hardware components such as wire, hinges and screws. Stainless steel is an alloy of iron, chromium and nickel. Metallic nickel has been classified as a possible carcinogen and is on the Prop 65 warning list.

What testing does EnChroma perform on its frames?

EnChroma uses an independent third party laboratory to test its frames and lenses for compliance with international standards including EN 16128:2015. EnChroma frames are compliant with the requirement for upper limit of nickel migration as specified in paragraph 1(b) and (c) of entry 27 of Annex XVII to the REACH. REACH is a European Union regulation concerning the Registration, Evaluation, Authorisation and restriction of Chemicals. However, the REACH is not recognized by the State of California. For more information and Prop 65 and how it applies to eyewear and EnChroma products contact

NOTICE: EnChroma glasses are an optical assistive device for enhancement of color discrimination in persons with color blindness; they are not a cure for color blindness. Results vary depending on the type and extent of color vision deficiency per individual. EnChroma does not endorse the use of the glasses to pass occupational screening tests such as the Ishihara test: these tests may be required in occupations where public safety is at risk such as public transport operators, electricians and first responders. Wearing of any filtering lens including colored contact lenses during test administration is prohibited and may invalidate the accuracy of the results.

Life changing experience!

Got these for my partner for her birthday and she loves them. They fit well over her glasses and she loves the sturdy case they came with. We hope that someday enchroma could make prescription glasses so she can see color indoors too.

Indoor Selection ones, not to Satisfied with But…here goes

My Spouse purchased a decent pair of Glasses from Amazon, and for the first time ever, I saw most shades, and Hues however, to much Pink/Red. I researched more and stumbled across this website that Strongly Recommended a Strong Protan. Once I received the Cx-3’s? BAM. I was a bit hesitant considering the $300+ Tag, however, once I put them on, I fell asleep the first night with them on my eyes, accidentally! Immediately the next day I went on the town and Holy Cripe, I actually saw FULL Shades, and Hues and didn’t realize how much the color Red Effects nearly every Color! Including Green. I saw grass as just Green grass, but never the Subtleties within and/or on Trees!! I’m a Grown Man over 40, and I had a Plethora of feelings of being Overwhelmed! I have new Lease on my Vision! 20/10 Excellent Vision, no Prescription, just lack the ability to acquire the Depth and True Colors. I was like a kid in a candy store watching the Tracking EVERY day. Expensive, yes. Worth it? Heck yea! I hope to not break mine, however, I would reorder in NY Minute. If I lived in NY… lol
In my photo, without Glasses I saw bland orange of my shirt. With, I see how LOUD orange it is! Those not Color Deficient, Red/Green, Green Red, Blue… It’s worth … priceless imo
