    • PROPRIETARY SPECTRAL LENS TECHNOLOGY: Our award-winning high performance eyewear for color blindness are uniquely engineered to enhance color vision and bring clear, vibrant color to your world.
    • OUTDOOR and INDOOR GLASSES: Our Outdoor glasses deliver the maximum color impact and also serve as ideal sunglasses for bright days. Our Indoor glasses are designed for lower light conditions such as viewing computers and TV. As a result, colors will be less enhanced with our Indoor lenses than with our Outdoor lenses. Most EnChroma customers purchase the Outdoor glasses first due to its versatility and full daytime color experience.

Trivex exceeds FDA impact resistance standards by more than 50x and is recommended by eye doctors for use in safety glasses and children’s eyewear products. Learn more about Trivex lens material.

    • 100% UV PROTECTION :  All EnChroma lenses are 100% UVA and UVB absorbing. According to the World Health Organization, UVA rays are unfiltered by the atmosphere and can cause the most damage to vision health.
    • CLARITY-ENHANCING, DUAL SURFACE, ANTI-REFLECTIVE LENSES: EnChroma lenses are anti-reflective on both sides of the lens to maximize clarity and reduce haze. This virtually eliminates lens surface reflections to see the world the way it truly is.

Absolutely love them, except...

They work fantastically, are comfortable, and look fairly good. My single complaint is the nose rests... they don’t stay put, but widen back out within a few minutes of being adjusted.




Its been about an hour (sorry i did read instructions and it said 10 but...) and i notice no immediate difference it feels like im just putting on shades indoors

Hi, Evan! It's possible that you will see more success with more wear! It can take time for the glasses' effect to kick-in as the brain adjusts to the newly altered light signals it is receiving.
Do they work?

I purchased the Menlo model for indoor use. I notice that there is definitely a color shift with red. I tried to see if I could then be able to identify more of the swatches on the color test and I don't think I can identify anything more than I could before. I'm not sure if the glasses are a gimmick or I have a defective pair or they don't work for me, but I don't SEE much of a difference.

Hi, Chris! Our glasses are not intended to be used to pass the Ishihara test. Passing the test would require a lens that distorts color, while our lens' goal is to help alleviate color confusion without sacrificing color accuracy. Additionally, if you do not see immediate results, we recommend wearing your glasses for at least 10 total hours over the first two weeks of ownership. This allows the brain enough time to adjust to the newly altered light signals that it is receiving! Hopefully this is helpful! Thank you for trying EnChroma.
