EnChroma Altavista is our fitover wrap-around frame that delivers superior coverage and clear, vibrant color for those with mild, moderate and strong Protan color blindness. Altavista fitover glasses are designed to be conveniently worn over prescription glasses. Wrap-around construction enables excellent coverage from stray light through the top and side of the frame. Buy Altavista FItover sunglasses, ideal for those with sensitive eyes or medical concerns. To wear over prescription glasses, the total width of the prescription glasses should be 135 mm or less (5 3/8ths inches), and the height of the glasses 42 mm or less (1 5/8th inches). To reduce internal reflections between the lenses, glasses that have an anti-reflection coating are recommended.

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. 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.

Starting Over

After 70+ years of learning the names of the colors I see, by asking others, I will have to start over with new colors for the old names. Hopefully, I will do this quickly.
My Altavista Fitover Cx3 Sun SP seem to change the purples I used to think were blue and the pink that looked gray. Still getting used to them but really like them, so far.

They’re for my dad in FL, & we are giving them to him on 28Dec to celebrate his 80th Bday, which is on 7Jan23. I’ll invite Enchroma to his FaceBook Surprise 80th Bday Party! Thank you!

Altavista Fitover outdoor

Wow! All this time I thought McDonald's buildings were brown. They work best in bright sunlight and just take them off when the light level is too low. One caution is that they take getting used to when driving. Color is so much different than what I am used to.

The most vivid colors I ever imagined!!!

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.
