Receptor Fitover outdoor glasses can be conveniently worn over prescription glasses. The wrap-around design provides excellent coverage from stray light through the top or side of the frame. Those with sensitive eyes or medical concerns for eye protection should use this frame for its superior coverage. A hard case is included for safe storage.

The frame measurements are 62-12-135 mm. To wear over prescription glasses, the total width of the 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.

  • 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.

Love them! Thank you!


I purchased these glasses for my son, who is 20, and my dad, who is 68. Both are protans. We were all scared to believe they might work, but they sure did. Both of them said they saw colors they didn't know existed and even mentioned seeing more depth in the clouds than before. My mom has red hair, and my dad had never seen her true hair color until this weekend! He had always seen it as a sort of auburn, he thinks, but it's definitely not auburn! He said even her skin looked like a different color. She asked, "Do you still like me?" He answered, "I think I like you even more." It was AWESOME! Both my son and my dad were seeing subtle shades of colors, and neither of them had truly seen bright red before. Two cars down the street were maroon and bright red. They thought they were like a blackish and brownish until they put on the glasses. They both kept commenting about the brick on the outside of the house and how vibrant it really is. They described their sight before as washed-out and are completely floored at how vivid the world is. My son, who is usually not very expressive about emotional things said, "The world is actually really beautiful." I AM ESTATIC. We are getting indoor and outdoor pairs for both of them. Thank you guys so much for changing lives this way. I wish everyone with hearing and sight problems could have something like this to help them experience the world. Wow.


The enchroma-glasses are a real marvel for me. Every time I wear them, I feel myself in a new, colorful world.

Fitover glasses

These are great! I'm seeing things I've never seen before like different colored foliage , flowers, and signs. I can't believe the difference! As soon as I put them on I discovered my neighbor has a dark maroon car instead of a black one. The colors of traffic lights are now obvious and stand out against the sky. I now know why red is used to attract attention, before, it it blended in with everything else now it obviously stands out. I love these glasses.

Bought for matching color coded data wiring

EnChroma Receptor Fitover glasses work and I can now see the colors. I wish they let in more light. Most of my color needs are located indoors in relatively dark places. Maybe there is a better model I should have bought.

Hello Walter, We are glad to hear that you can see the full spectrum of color with your EnChroma glasses. In regards to your indoor color needs, our indoor glasses are designed to be used in lower light settings for activities such as cooking, watching movies, browsing the web, and art projects and work in classroom settings. Because light influences color perception, brighter lighting conditions produce a more impactful color effect on outdoor lenses. We hope this information is helpful.
