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.

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

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

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. 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.

Altavista Fitover Cx3

This is my 3rd pair of glasses I've ordered. The last pair like this has been with me every day for 2 years in 3 different continents and 13 countries. I replaced them with the same style since they are great and brought me colors I've never seen. After 2 years it was just time to get new ones before i leave the us again. I've shown them to many people in Asia and Europe and the response was great.Well made and sturdy. I've made a slight modification to the earpieces by drilling 2 small holes in the rear to attach a locked in cord on both pairs. It has saved the glasses from going into 2 oceans and for that I'm happy. I think it should be offered by enchroma on new models. I used a small drill bit and a safety cord off of another pair of glasses I bought at a truck stop to do this to the new glasses..

Amazing for a 75 Year Old

I am 75, and have obviously lived with demonstrable color blindness all my life. I had healthy skepticism before ordering, so my expectations were realistic. The first time I put them on, there was a significant difference for the better. It has only improved over the last week or so I have had them. I now see multiple shades of green, and most colors are much more vibrant. One thing I know for sure: I want a little red sports car before I die, to do road trips and see everything in real colors!

Enchroma Fit Over Review

Enchroma has a nice product, but you should not expect a miracle. I use them when driving and while outdoors and they greatly enhance the reds and greens around me. They allow me to see more clearly the oranges and purples, too, but they are not the end all for protanomaly color blind people like me.

I confess that when I first put them on I didn't get the earth shattering revelation some have had on the videos, but after wearing them for a couple of hours I realized my fence was red and the photinias in the back yard had some beautiful red growth. I had NEVER seen these before. Flowers in general are amazing more beautiful.

My final assesment is that they are worth every penny as an aid to seeing color, but don't expect that they will completely eliminate your color blindness.

This is exactly how enchroma advertises these glasses. My expectations were met, but I was disappointed I didn't have the earth shattering experience like some of Youtube.

I"m sure over time they will get even better and I am considering purchasing the indoor version.
