6 Surprising Facts About Your Eyes
Believe it or not, eyes are some of the most complex organs in the human body. How much do you know about your eyes? Read on for some fascinating facts about your peepers.
1. Your Eyes Say A Lot About Your Health.
From AIDS to high blood pressure, ophthalmologists can tell a lot about the state of your health just by looking at your eyes. They’re truly an extension of your overall well being.
2. Your Eyes Get a Workout.
The muscles that control your eyes are the most active in the entire body, and, arguably, the strongest.
3. Your Makeup May Not Be As Safe As You Think.
From scratched corneas to eye infections, cosmetics can cause serious harm to your health. If used properly, including not sharing makeup with others and throwing it out when it’s too old, eye makeup is generally safe. In the United States, the Food and Drug Administration (FDA) regulates cosmetics, but doesn’t have the same control over imported makeup. Imported makeup can sometimes contain dyes and other chemicals that are banned from use in the U.S. Luckily, the FDA has a list of products to look out for — you can check it out here.
4. Your Eyes are Resilient.
Eyes are an astoundingly strong organ. With the protection of the eyelid and lashes, layers of fat, muscle, and skin, as well as 3 layers of tissue on the eye itself, it really does take a lot to damage your eyes. Most superficial scrapes will heal within a few days or less — much faster than your skin.
5. Blue and Green Eyes Are a (Relatively) Recent Development.
For nearly all of human history, every person on the planet had brown eyes. Scientists speculate that it wasn’t until the past 6,000-10,000 years ago that blue eyes came about. It’s thought that this mutation arose in just one person, and spread overtime throughout much of eastern and central Europe.
6. What You Think Damages Your Eyes Probably Doesn’t.
Reading, or any activity that requires a lot of eye focus, isn’t actually bad for your eyes at all.
