~~no no no,~~ they also gets oxygen supply from the back of your eyelids (and also oxygen dissolved in you tears). otherwise you'd have to keep your eyes open when you sleep.

So that's why we're not supported to open our eyes under water. Our eyeballs are suffocating!

If our eyes can absorb oxygen from tears then they can certainly do so when submerged provided the water is sufficiently oxygenated.
