Introducing EnChroma® Monterey, our newest, lightweight wrap-style frame with EnChroma outdoor lenses is designed for most outdoor sports and adventure. Our lenses are engineered to improve color vision and are 100% UV absorbing with frames that wrap the face to protect against wind, dust, dirt, and the sun’s harmful rays. These Italian-designed frames are made from TR-90, a light nylon-based material known for retaining its shape to provide a long-lasting, comfortable fit. Frame size: Large 63-14-120. Fits most adults.
  • 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?

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.

Birthday gift for Dad

I got these for a gift for my dad for his 70th birthday and he was thrilled! He has always loved and appreciated nature's beauty, but he didn't even know what he was missing. We live far apart, but he keeps texting me, emailing me, and calling me with stories of the purple flowers he saw, how green the trees look, and that he never knew that the red in the flag is not supposed to look washed-out!


I am a 60 year old man who is partially color blind, red/green deficiency. My son gave me a gift certificate for enchroma and I ordered the CX3 sunglasses. I did not expect it to really work. Wow, I was wrong. They recommend wearing for multiple times since not everybody works immediately but I was one of the lucky ones. Major change as soon as I put them on! I sawhues I had never seen before. I keep raising them up and down to see the differences....VERY SATISFIED CUSTOMER!. I am considering getting my regular glasses from Enchroma but probably won't since there are no optometrists in my immediate area that work with Enchroma.

Monterey Cx3 Sun Glasses

I recently purchased the Monterey Cx3 Sun Glasses. I didn't realize how much COLOR I was actually missing. Just WOW. I'm now going to buy some indoor glasses so that I can experience true color 24/7.
Truly amazing! Red are actually RED! pink is not off white! While driving green/red lights so much more brighter and actual color! Worth every dollar! Don't hesitate like I did.😎

recent purchase

really has changed my perspective on colour and depth perception. colours even i thought i was great with like red, im finding out i have lots to learn. thanks Enchroma for brightening up my world! also i have an average size head and they fit perfectly 🤣

Strong protan, glasses work well!

I bought the Monterey SP sunglasses for my husband, was a bit scared that the frame would be too large for him bc his face is tiny but it's not. He was actually very happy with the fit and they are practical for all outdoor activities, for us it's mainly hiking. My husband can see red and purple for the first time! Red looks more like a shade of brown for him so he was like wow, is red really "screaming" this much? Or now I get the red mustang thing.. :) Also purple.. for him it's a shade of blue.. and he found out that our neighbor's house is light pink instead of grey as he had seen it. Bricks were also surprisingly red. :) He said green looked the same, we went to the forest and no changes but the glasses helped him to distinguish some specific shades of green and yellow on PC. The only thing is that the sky and white clouds seem to look a bit pink for him but it adjusts after a few minutes of wearing the glasses.. Overall, he was very happy with the results and the glasses worked immediately. No crying as in the online videos though. :)
