Some crazy facts about Human Eyes.
80% of vision problems around the world are avoidable or even curable. Advancements in LASIK SURGERY as well as preventive care through supplements and diets contribute to this.
Shark corneas are very similar to the ones we humans have. Because of that similarity, they’ve been used as replacements in human EYE SURGERIES.
Your eyes are made up of more than two million working parts to make them fully functional.
Out of every muscle in the body, the ones that control the eyes happen to be the most active
This eye condition happens when a person is born with two differently colored eyes.
On average, an eyeball is about an inch in diameter and weighs around 0.25 ounces.
The nerve, which connects the eyes to the brain, is too sensitive to successfully reconstruct.
In spite of their crying sounds; tears don’t begin to flow until they’re around 4 to 13 weeks old.
With the proper care, it will only take around 48 hours for the eye to repair a corneal scratch.
Tears are made up of three different components, namely fat, mucus and, of course, . If these three components aren’t exactly in their right quantities, your eyes could become dry. Your brain responds to such dryness by producing more of them!
The very first person to ever have lived around 6,000 to 10,000 years ago. Back then, everyone had brown eyes.
A blink usually lasts 100 to 150 milliseconds and it’s possible to blink five times in a second.
For around 99% of the population, the age they’ll first need reading glasses is between 43 and 50. This is because the lens in your eye slowly loses its focusing ability with age.
Right behind the pupil is the lens, which focuses on objects you look at. Take a moment to look around a room and think about the various distances you’re focusing at. Each time, you do this, your eye’s lens instantly changes focus without you even being aware of it. Compare that with a camera’s lens which takes a few seconds to focus between this distance to the next.
Blinking helps remove any debris on your eye’s surface by spreading tears over them. The tears help moisten and lubricate the eyes and they also have important anti-bacterial properties.
