  • 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.

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.

Purple is the best.

Reds & greens come to life

Reds and greens have always been dull to me which I realized after trying on my new EnChroma eyeglasses. Suddenly bright rich colors were being observed. And not only the basic reds and greens, but rich yellows, oranges, pinks and purples also. A granddaughter’s orange car changed to a reddish orange. Green traffic signal lights, almost white to my eyes, became a light green. The red signal lights became a bright red, and more easily detectable from a distance. It was sometimes difficult to see a stop sign with green foliage in the background, especially in low light conditions. They now stand out a bright red. Observing the various colors in a flower bed is quite a treat. I must agree with the claim that the experience is life changing is true. A genuine feeling of gratitude exits now at the tender age of 78 as accurate colors are being observed.

I have been able to see the red in places I had never seen before!! I have also been able to see pink, orange and green with different eyes!! Sunsets have become a completely different experience all together!!

Julieta R. (Tampa, US)
Loved them!

Light weight, comfortable for all day wear. I am a truck driver and I can have them on all day! Thank you!

A wonderful Father's day gift

It definitely makes colors more vivid even for non-color blind individuals like me who gave it a try. The customer service is also wonderful and shipping outside the US was fast!

Did not work for me

The company was efficient but the glasses did not work for me. I saw very little difference in colors with glasses on or off and I tested Strong Protean.

Thanks I really do enjoy the glasses that was given as a gift.

In my particular case with slight red colour deficiency, red seems about 40% btighter, but green slightly dull than without the glasses.

Hope it helps

Thankful and blessed!

We gave my father a pair of Enchroma glasses as a gift to him as well as ourselves on Mothers Day. At the age of 67 he was able to see color for the first time. We purchased the Canyon style and were super pleased with the looks of the glasses as well. So very thankful and blessed!
