Eyes are incredible organs, revealing more about the fascinating human body than most realize. Here are some captivating facts about them:

Eye Size Throughout Life

Did you know that human eyeballs remain roughly the same size from birth until death? The size of an infant's eye is about 16 to 17 mm in diameter, growing only slightly to 24 mm in adulthood.

Corneal Healing Abilities

Here's another eye-opener: the cornea, the transparent front part of the eye, can heal itself from minor abrasions in just 24 to 48 hours due to its high regenerative capability.

The Truth About Blue Eyes

Blue eyes aren't actually blue! Surprised? This is because there is no blue pigment in eyes. The blue color is due to the scattering of light in the stroma of the iris, a phenomenon known as Rayleigh scattering, which is also why the sky appears blue.

Red Eye in Photos

Ever wondered why eyes turn red in photos? It's because the flash reflects off the blood vessels in the retina.

The Blinking Phenomenon

Lastly, consider this: on average, a person blinks about 15 to 20 times per minute, adding up to around 14,000 times a day and approximately 5.2 million times a year. Blinking not only helps keep your eyes moist but also protects them from irritants.
