The eye

Eye-Popping Fact ONE: A crucial part of your eyes is as flimsy as a wet tissue! 

Eye-Popping Fact TWO: You blink more than 10,000 times a day!

Eye-popping Fact THREE: Your eyes adjust in milliseconds to ANY movement of your head!

Eye-Popping Fact FOUR: Your eyes see everything upside down and backward!

Eye-Popping Fact FIVE! Your pupils change size whenever the light changes!

Your black pupils may be small but they have an important job – they grow or shrink to allow just the right amount of light to enter your eyes to let you see. Try this: Go into a windowless room, turn off the light and close the door so there is just enough light to see the pupils in your eyes in the mirror. Your pupils will be far larger than usual, having grown to their maximum size to capture as much light as possible. Now, turn on the light while still watching your pupils. You’ll see them shrink to a small dot almost immediately – right before your very, um…eyes!
