From the moment I wake up in the morning to the time I try to sleep at night, my eyes are working non stop acting like a camcorder. Everything I look at is then sent to my brain (do I really have one?) for processing and storage much like on a DVD.
Our eyes are a very complex part of our bodies and nature has provided many features which protect the eyes. The eyebrows are the strips of hair above your eyes which prevent sweat from running into them. Eyelashes help keep the eye clean by collecting small dirt and dust particles floating through the air. The eyelashes also protect the eye from the sun’s and other light’s glare. The eyelids sweep dirt from the surface of the eye. The eyelid also protects the eye from injury. Tears are sterile drops of clean water which constantly bathe the front of the eye, keeping it clean and moist.
Did you know…..
Most people blink every 2-10 seconds.
Each time you blink, you shut your eyes for 0.3 seconds, which means your eyes are closed at least 30 minutes a day just from blinking.
If you only had one eye, everything would appear two-dimensional. (This does not work just by closing one eye.)
Owls can see a mouse moving over 150 feet away with light no brighter than a candle. The reason cat’s and dog’s eyes glow at night is because of silver mirrors in the back of their eyes called the tapetum. This makes it easier for them to see at night.
An ostrich has eyes that are two inches across. Each eye weighs more than the brain. A chameleon’s eyes can look in opposite directions at the same time.
A newborn baby sees the world upside down because it takes some time for the baby’s brain to learn to turn the picture right-side up.
One in every twelve males is colour blind.
