Eye Factoids
Some things you probably didn’t know about eyes and vision!
Our eyes have many parts. The black part on the front of our eye is called the “pupil”. It is really a little hole that opens into the back part of our eyes.
Over the front of our eye is a clear covering called the “conjunctiva”.
The space between your eyebrows is called the glabella.
The highest recorded speed of a sneeze is 165 km per hour.
A human eyeball weighs an ounce.
In the United States each year, approximately 25,000 eye injuries occur that result in the person becoming totally blind.
If the lens in our eye doesn’t work quite right, we can get glasses to help us see. Glasses have lenses in them that work with our eye’s own lens to help us see better.
The eye of a human can distinguish 500 shades of grey.
The cornea is the only living tissue in the human body that does not contain any blood vessels.
Shark cornea has been used in eye surgery, since its cornea is similar to a human cornea.
Around the pupil is a colored muscle called the “iris”. Our eyes may be BLUE, BROWN, GREEN, GRAY OR BLACK, because that is the color of the iris.
Just behind the pupil is a lens. It is round and flat. It is thicker toward the middle.
The most common injury caused by cosmetics is to the eye by a mascara wand.
Some people start to sneeze if they are exposed to sunlight or have a light shined into their eye.
Babies’ eyes do not produce tears until the baby is approximately six to eight weeks old.
Men are generally able to read fine print better than women can.
Research has indicated that a tie that is on too tight can increase the risk of glaucoma in men.
The number one cause of blindness in adults in the United States is diabetes.
Our eyes are very important to us, and we must protect them. We don’t want dirt, sand, splinters or even fingers to get in our eyes. We don’t want our eyes to get scratched or poked. That could damage our sight!
Blinking helps to wash tears over our eyeballs. That keeps them clean and moist. Also, if something is about to hit our eye, we will blink automatically.
The white part of our eye is called the “sclera”. At the front, the sclera becomes clear and is called the”cornea.”
Inside our eye, at the back, is a part called the “retina”. On the retina are cells called “rods” and “cones”. These rods and cones help us to see colors and light.
It is impossible to sneeze with your eyes open.
The reason why your nose gets runny when you are crying is because the tears from the eyes drain into the nose.
All babies are colour blind when they are born.
People generally read 25% slower from a computer screen compared to from paper.
Sailors once thought that wearing a gold earring would improve their eyesight.
The conjunctiva is a membrane that covers the human eye.
Our body has some natural protection for our eyes. Our eyelashes help to keep dirt out of our eyes. Our eyebrows are made to keep sweat from running into our eyes.
We should never put anything in or near our eyes, unless we have a reason to use eye drops. We would only do that if our doctor or parent told us to use them.
