  • 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.
  • 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.

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.

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. Read More

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.

Gave a new perspective of colors!

I've worn this Grant Cx1 Indoor DT glasses for over a week now. Didn't really work when I first wear it, took awhile before it helped improved my color perception. Although I don't see any significant changes, it has helped and will probably help me more in my daily work where I am required to distinguish colors most of the time.


Glasses are amazing! Colors (especially red, greens, and pinks) are exceptionally vibrant and appear exponentially brighter than normal. Would definitely recommend

Third pair now Grant Cx1 Indoor

I've been using Encroma daily for the last 2 or 3 years. I started with indoors and it was a slow process of recognizing colors I had never seen (green & purple). I bought the outside type and they are much faster helping me to see colors. The combination is great. The new type I am wearing now, the Grant Cx1, I like very much. The previous one I had was a very nice style, but the tint was pink and it called too much attention. These are like a brown orange/red and it is a much better tint for me. I've replaced the others, because they had lots of little scratches, I don't know why, they were supposed to be scratch resistant. In any case I will be more careful. The style is great and fits perfectly.


My husband had never seen colors right for almost 35 years. These give him the opportunity to see what we see and to do his job safely as an HVAC tech. Thank you.

They made my Dad happy

Thanks for your efforts in doing something good for the people. I would like to ask you to try to make the glasses accessible to a wider range of people by adding cheaper options maybe? that would be perfect. Keep up the good work:)
