New! EnChroma Eton is a sophisticated, yet sporty-styled rectangular frame with crisp corners, a curved brow line, and a sculpted saddle bridge for a great look. Eton is so versatile, you might never have to take them off. They are classy enough to wear at a commencement speech, yet sporty enough to wear on a hike, or on the links. Our Cx3 Sun lenses make Eton the perfect sunglasses for most types of color blindness.

Made from durable, lightweight TR90 material, Eton will hold its shape for the life of your glasses. 100% UV protection. Case included. Rx capable.

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.

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 to my 73 year old father in law

I had my father in law take the color blind test, and then surprised him with the sunglasses. We all lined up with colored balloons outside and he opened the gift. He was blown away by the difference in colors, and now he’s walking into the grocery stores talking about how vibrant the fruit colors are. He also told use he can tell the difference between a red and green traffic light - before it was only based on the position of the light, and now he can see the difference. He’s really pleased with them and wears them everywhere. After 73 years he got the gift of color.

Wish I Had Not Waited

I had my husband take the Enchroma color blind test in Nov 2018 so I could know what type of glasses to get him. He is a Strong Deutan. I kept putting it off because he does not like to spend money on himself. I finally got the Eaton Cx3 Sun glasses for him and it has been amazing. He looked at my pink shirt I had on and he said, “I always thought that shirt was orange!” He saw that the stickers on the license plate were bright yellow instead of pale green. He came back from a trip to the store and said he was completely sold on the glasses after he saw beautiful pinks and reds in the flowers on the way. I am so happy and wished I had not waited. Now to get a pair for indoor and another for his 87-year-old grandmother who we just learned is also color blind. Thank you!

Dad sees all the colors now!

My sister and I purchased these for our dad for a Father’s Day/Birthday gift. He wears them all the time now and said he can see more colors, brighter colors and more variations in color shades. I’d highly recommend these for the color blind person in your life.
