Anisocoria means that one of your eyes looks bigger than the other. Your eyes are like little cameras that help you see things. They have a part called the pupil that lets light in so you can see. When one of your pupils is bigger than the other, it's called anisocoria.
Now, there could be many reasons why this happens. It could be because one of your eyes is more sensitive to light or because something is blocking the light from going into one of your eyes. Sometimes, it can even be a sign of a health problem.
If you notice that one of your eyes looks bigger than the other, it's important to tell a grown-up that you trust, like your mom or dad or a teacher. They may take you to see a doctor to make sure everything is okay with your eyes. It's always good to take care of our eyes so we can see our world clearly!
