    Fun fact: Cutaneous respiration (aka “Skin breathing”) is something we humans do too. But it accounts only for 1% to 2% of our oxygen input.

    However, the cornea of ​​our eyes doesn’t have its own blood vessels to supply it. Therefore, it relies on direct gas exchange with the environment—in other words, skin respiration.

    Our eyes breath like bees.
