What is a Protan?

Protans are people with protanomaly, a type of red-green color blindness in which the red cones do not detect enough red and are too sensitive to greens, yellows, and oranges.

As a result, greens, yellows, oranges, reds, and browns may appear similar, especially in low light. It can also be difficult to tell the difference between blues and purples, or pinks and grays.

What are Enchroma glasses?

Enchroma glasses look like ordinary tinted glasses, but the effect they have on color vision is extraordinary. If you have red-green color blindness, Enchroma glasses can reveal a greater spectrum of color without compromising either color accuracy or balance.


People with moderate protanomaly usually respond positively to Enchroma glasses — 75% of people with test results like yours experience improved color vision. However, the effect is sometimes subtle and you may need to wear the glasses a few days before you start to notice it. You can try our glasses risk free. We accept returns for any reason within 60 days.
