ELI5: Explain Like I'm 5

Haploscope

A haploscope is like a pair of glasses that you wear to look at pictures or things that are far away. But instead of just using them to see things better, they help scientists study how your eyes work together.

You see, when you look at something with both of your eyes, your brain takes the information that each eye sees and puts it together to make one picture. It's kind of like a puzzle, where each eye is a piece that needs to fit perfectly with the other one.

Scientists can use a haploscope to show your eyes two different images at the same time. So your brain has to work extra hard to put both pictures together into one image. This helps scientists learn more about how your eyes work together and how your brain processes visual information.

It might sound a little complicated, but don't worry! All you have to do is look through the haploscope like you're wearing glasses, and try to focus on the pictures you're seeing. It's like playing a game with your eyes and brain!
