HOW IT WORKS

It's not just a filter. It's science.

Three steps from "I see grey" to "I see green."

01

Your Eyes

In protan color blindness, your red photoreceptors overlap too much with green. Your brain blends them into mud.

02

Our Lens

Our Outdoor Protan lens removes the overlapping wavelengths, boosts reds, and normalizes the green-to-red ratio.

03

Your World

Reds get redder. Greens get greener. Most users see the difference within minutes — some need a few wears for the brain to catch up.

The first time I saw red. I have very protan colorblindness. Put these on at the beach. The sunset literally stopped me. My wife filmed me crying. Worth every dollar.

The gift of color. 33-year-old deutan here. Wore them for the first time in my backyard. I hadn't realized how much green I was missing. The frame is also a beast — wraps tight, doesn't slip during runs.

Bought for my husband — life-changing. He took the test online, picked Outdoor Deutan. The look on his face when he saw our daughter's red hair properly for the first time. Thank you.

QUESTIONS

Have a question? We're here.

EnChroma glasses are designed to enhance color vision for people with red-green color blindness, including Deutan and Protan types. They are not designed for complete red-green color blindness, such as Deuteranopia or Protanopia, or for blue-yellow color blindness, such as Tritanopia. For best results with outdoor lenses, wear them in bright sunlight.

EnChroma purchases made directly through enchroma.com are backed by a 60-day return policy. We recommend giving your eyes time to adjust and confirming you selected the correct lens for your type of color blindness. Exchanges are free if you need a different lens.

Deutan and Protan lenses are designed for different types of red-green color blindness. Deutan color blindness is the most common type and can make red, yellow, green, and brown appear similar, especially in low light. Protan color blindness affects how red light is perceived. For the best experience, choose the lens that matches your color blind test result.

If you’re not sure which lens is right for you, take the EnChroma Color Blind Test before ordering.

Some EnChroma frames are available with polarized lenses. If the O’Neill style you’re viewing is polarized, it will be listed in the product name or lens details on the product page.
