This Halloween, we've compiled a list of interesting and SPOOKY facts about the human eye. Some of them may seem familiar, but others are sure to give you the creeps!
- Your eyes are always working their best, while other parts of the human body typically need to warm up before they can perform their best.
- 80% of our memories are determined by what we see. Also, 80% of what we learn is through our eyes.
- Newborn's don't actually produce any tears. They make "crying" sounds, but no tears start developing or flowing until they reach 4-13 weeks of age.
- Doctors, although now able to transplant many things, are still unable to transplant eyeballs. The optic nerve is too complicated and sensitive to reconstruct successfully.
- Seeing is so complex that it requires roughly half of the brain to get involved to do so.
- The eyes heal so quickly that if you were to scratch your cornea, it would only take about 48 hours for it to heal. (Talk about super powers!)
- 80% of vision problems are usually avoidable and even curable.
- The average blink only lasts for 1/10th of a second.
- Of all the muscles in our bodies, the ones controlling the eyeball are the most active muscles.
- Some people have two different eye colors. This is called heterochromia.
- Each eyeball has a "blind spot" in the back of the retina. You've never noticed it before, because the other eye compensates for the hole in your vision. (Pretty neat, huh?)
- Blue and green eyes are recessive traits, so even if no one in your family has had those colored eyes in several generations, you could still be born with blue or green eyes!
- On average, you will blink only 12 times every minute.
- Only 1/6 of the human eye is exposed and visible.
- "Red eye" occurs in photographs because the light from the camera flash bounces off the back of our eyes, illuminating them. (And also makes them look super creepy!)
