Features
  • 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.
  • ULTRASONICALLY CLEANED AND UV SANITIZED: Every EnChroma Certified Refurbished pair of glasses is rigorously cleaned, reconditioned and inspected to function as new and meet our strict quality standards.
    Our ultrasonic bath cleaning, uses high-frequency sound waves to dislodge any tough to reach debris and dirt. Once dried, the eyewear is loaded into a UV sanitizer, similar to Ultraviolet C (UVC) light used by hospitals. UV sanitizing of lens and frame surfaces is an important cleaning method without using extreme heat that can damage eyewear.
  • 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 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 P65Warnings.ca.gov.

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 support@enchroma.com

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.

We love them!!

My stepmom and I bought these as a present for my dad and they have worked wonders for him! When he first tried them on they didn’t really seem to work but after having them on just a few hours they started working. I highly recommend!

Thank you for letting me see a different world.

This is a pair of magical glasses. After wearing it, it is incredible that red and green are easier to distinguish.

This changed my husband's life!

If you're considering investing in a pair of these glasses, but doubt the reviews, I was skeptical too. My husband has been a tattoer for 20 years, but could only see a watered-down, muddy color spectrum. He's always been a bit saddened by this, being a passionate artist with a deep love for color. I bought him a pair of Enchroma glasses and surprised him with the gift as we boarded a hot air balloon ride for his 44th birthday celebration. He was profoundly affected. As the sun came up, he finally saw the earth in full-color. He kept going on about how bright everything was and how many shades of green there were. For people who see full color, we all take for granted the way things looks on the day-to-day. But, to watch him see that world for the first time in his life, it was very emotional. I am ever grateful ❤️As is he.

Not a dramatic change for everyone

I bought a pair of refurbished Bancroft Indoor glasses. Been using them during daylight hours for a couple of weeks now.

Even as indoor glasses these will need daylight levels of light in order to see their effect. I have a mild protanomaly, and these glasses only make a minor difference. Reds are way brighter, surprisingly blues are bolder (probably owing to the blip in red cone light reception at the blue end of the spectrum), purples are something I don’t believe I’ve seen before. However I have to search to see these differences, they’re not popping out at me like I thought they would. I think this is down to how I’ve learned to see the world - I don’t pay attention to colour on a regular basis and this is a difficult thing to learn to do after 35 years! I was hoping that I’d be able to appreciate autumn colours more but I’m still not sure if I can see any reds in the leaves. The difference between yellows and greens is more apparent though.

Great for shopping fruit

While they do not help at me all distinguish colors in board games and card games, which I originally bought my pair of Enchroma Bancroft indoor glasses for, they have turned out a great help when shopping for fresh fruit. Where I formerly had to take e.g. strawberries, pears or tomatoes into the best-lit spot I could find, and squint really hard, I can now simply put on my Enchroma glasses and immediately see whether or not they are fully ripe and red. Also, brown spots and blemishes stand out very clearly, where without the glasses I needd to actively and meticulously look at each fraction of a square inch of each individual fruit, or risk missing bad spots and buying fruit that will spoil sooner.
