What is deuteranopia?

Deuteranopia is when someone can’t see certain colors as well as others because their green color vision doesn't work quite right.

Imagine you have a box full of crayons, red, blue, yellow, and green. Most people can tell them all apart easily. But if you have deuteranopia, the green crayon might look more like the red one or the blue one. It’s like your eyes are wearing a special kind of glasses that make green harder to see.

How it feels

If you have deuteranopia, sometimes you might mix up colors in pictures or on the playground, like thinking a green ball is blue or red. It can feel like everyone else sees a bigger, more colorful world than you do, but that’s just because your eyes work a little differently.

What it means

It doesn’t stop you from having fun or learning new things, it just means you might see the world in a slightly different way. Some people with deuteranopia wear special glasses to help them see colors better, like how some kids wear glasses to see clearly when they’re reading.
