People do not normally think about their eyes until they are forced to do so. It makes sense though. You should know that there are a lot of things that you may not know about your eyes.


Eyes started to develop over 500 million years ago in single-celled animals.


Your eyes start to develop in humans two weeks after conception.


The average lifespan on an eyelash is five months.


Eyes look the way that they do for protection. Our eyebrows protect our eyes from sweat and eyelashes keep dirt out of your eyes.


Your eyeballs stay the same size from birth to death. It is your nose and your ears that continue to grow as you age.


Your eye has more than 2 million working parts.


In an eye, only 1/6 is exposed.


The cornea is the only tissue that doesn’t have blood.


The human eye weights under an ounce and is about an inch across.


An eye cannot be transplanted due to more than a million nerve fibers connecting to the brain which cannot be reconstructed.


80% of our memories come from what we see.


Our eyes heal really quickly. If you have a minor scratch on your cornea it could take just two days to heal.


About 39 million people are blind.


80% of vision problems are avoidable or able to be cured.


Humans and dogs are the only species known to seek visual cues from another individual’s eyes.


A fingerprint has 40 unique characteristics, and an iris has 256.


Blind people can see their dreams as if they were not blind.


80% of what we learn is through our eyes.


Eyes are the second most complex organ only after the brain.


Our eyes may be complicated, but they are very important. They do a lot more for us than what we realize. It is important that we do what we can to take care of them, and when we do need treatment we need to see someone who is trustworthy.
