Default The Back of a Spoon
When trying to explain what astigmatism is, many people say that it's due to the cornea being shaped more like a football than a baseball.
Then I read the description that said that an astigmatic cornea is shaped like the back of a spoon.
Do we have any experts here that can agree with that analogy?
