Which part of your body lets you read your favorite story book? Check out a new movie, and see an angry dog heading your way? Which part lets you cry when you're sad and makes tears to protect it? Which part has muscles that adjust to let you focus on things that are close up or far away? If you guessed the eye, you're right!

Your eyes are at work from the moment you wake up to the moment you close them to go to sleep. They take in tons of information about the world around you — shapes, colors, movements, and more. Then they send the information to your brain for processing so the brain knows what's going on outside of your body.

But there are some facts about your eye you did not know, here are some of the cool ones:
• Humans can see more shades of green than any other color
• You actually see with your brain, not your eyes. Our eyes function like a camera, capturing light and sending data back to the brain.
• You see things upside down - it is your brain which turns the image the right way up.
• In a single second, it’s possible to blink five times.
• You are likely to blink more often when you are talking.
• The eye is the fastest muscle in your body – hence why when something happens quickly, we say ‘in the blink of an eye!’
• A blink typically lasts 100-150 milliseconds.
• The human eye can function at 100% at any given moment, without needing to rest.
• Red-eye in photos is caused by light from the flash bouncing off the capillaries in your eyes.
• If the human eye was a digital camera, it would have 576 megapixels.
• On average, you will blink approximately 4,200,000 times in a single year.
• We have two eyeballs in order to give us depth perception – comparing two images allows us to determine how far away an object is from us.
• Eyes heal quickly. With proper care, it takes only about 48 hours to repair a minor corneal scratch.
• The world’s most common eye color is brown.
• While a fingerprint has 40 unique characteristics, an iris has 256. This is why retina.
