5 Amazing Facts About The Human Eye, Rhinelander, Wisconsin

Your eyes allow you to make visual memories, stare in awe at nature, and create a colorful painting. These complex organs are key to interacting with the world around you, and they are incredibly interesting as well. The next time you visit your optometrist, discuss with them these five interesting facts about the human eye. 

Do You Know These Facts About The Human Eye?

Master Identifiers

You may be used to scanning your fingerprint for security reasons, but your eye is a more precise form of identification. While the human fingerprint has 40 individual characteristics, your iris contains 256. This is why higher tech security systems scan the eye. 

Sun Sensitive

optometristYour sunglasses do much more than help you look cool. Eyelids and eyes can actually be sunburned. Optometrists call this photokeratitis, and the surface of the cornea can become damaged like your skin when it’s burned. If you are experiencing pain, burning, redness, headaches, and sensitivity to light, you could have a sunburn on your eyes. 

Speedy Blinkers

The term “blink, and you’ll miss it” might not have as much merit as you think since humans blink at lightning speed. On average, a blink lasts just one-tenth of a second. Most people blink 28,800 times per day, but you usually don’t notice that you’re doing so. 

Popular Accessories

If you look around, you might notice that many people wear glasses. And if they aren’t, they are likely wearing contacts. Studies show that 61% of the United States population wears corrective lenses of some kind. And people appear to be wearing these visual aids more as they grow older. 

Powerful Healers

Every part of the body heals at a different rate, but the human eye works a bit harder. The epithelium, or the tissue that makes up the cornea, can generate new surface cells in just one week. This makes it one of the body’s fastest healing tissues. When you have a scratched cornea, see your optometrist, but know that the abrasion will heal quickly.
