It’s time for kiddos all around the country to head back to school. So to celebrate, we thought we’d fill your head with some “eye knowledge.”

We’ve always made it a point to talk about how incredible the eye is, but we thought we’d devote a post to these crazy, random eye facts. Some of them will blow your mind. Some of them you will find hard to believe. So just to keep our “street cred” we’ll provide sources for the nuggets of information that we deem “extra mind blowing”.

So here we go!

  2. Some women can have a genetic mutation which causes them to see millions of more colors.
