It’s a big word, but it simply means your eye isn’t completely round. Almost all of us have it to some degree.

A normal eyeball is shaped like a perfectly round ball. Light comes into it and bends evenly, which gives you a clear view. But if your eye is shaped more like a football or the back of a spoon, light gets bent more in one direction than another. That means only part of an object is in focus. Objects at a distance may look blurry and wavy. It’s fairly easy for an eye doctor to fix with glasses, contacts, or surgery.
