WHAT YOU NEED TO KNOW ABOUT EYES

Your eyes will automatically blink 6 times while you are reading these words. That is because you blink about 12 times every minute whether you try to or not. Buy don't worry - the average blink lasts 1/10th of a second so you want miss much. The tiny muscles that blink your eyes are the most active muscles in your entire body, yet the human vision process is an amazing and complex system which engages more than just your eyes. The optic nerve connects the back of your retina to the visual cortex of the brain all the way at the back of the head. Seeing these words right now requires about half of the brain to get involved. 

Did you count your blinks?
