How hard do you think this was for science to crack?
The answer says more about you than about the discovery.
- Yep, your eyes need oxygen from the air to do their thing. Wild, right?
- This lack of blood flow makes the cornea a biological anomaly.
- The cornea is also the fastest-healing tissue in the human body.
Your eyes are essentially scuba diving in the open air. While every other organ relies on the heart to pump oxygenated blood through a network of vessels, the cornea has zero blood vessels inside it.
Transparency is the priority here. If the cornea had veins, your vision would be obscured by a red, pulsating web. To stay clear, it evolved to absorb oxygen directly from the moisture on its surface and the atmosphere surrounding you.
This lack of blood flow makes the cornea a biological anomaly. Because there are no vessels to provide warmth or nutrients, the cornea relies on tears to deliver what it needs and wash away waste.
