Eye facts


Eye

  • 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.
  • 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.
  • 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.
  • 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!
  • The study of the iris of the eye is called iridology.
  • The shark cornea has been used in eye surgery, since its cornea is similar to a human cornea.

    • The white part of our eye is called the "sclera." At the front, the sclera becomes clear and is called the "cornea."

    • It is impossible to sneeze with your eyes open.
    • The space between your eyebrows is called the Glabella.
    • 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.
    • Just behind the pupil is a lens. It is round and flat. It is thicker toward the middle.
    • 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.
    • 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.
