Did you know there's a part of your body that breathes air directly?
Imagine you're wearing a mask that filters out impurities from the air you breathe. Now, think about a part of your eye that doesn't have blood vessels to filter air like your mask.
The cornea is like an air filter for your eye, getting oxygen straight from the air without needing blood vessels to transport it.
Example
Just like your mask filters air for you, the cornea filters oxygen for your eye.
Remember this
The cornea breathes in oxygen directly from the air, unlike most tissues that need blood vessels to transport oxygen.
