Fun Facts About Eyes

Here are some facts that you may not have known about eyes:

  • Our eyes have two million working parts, seven million cones that help us see colour and detail, plus 100 million cells that provide our night vision.
  • The average blink lasts for about 1/10th of a second.
  • A key reason eyes become tired at the computer: we blink less often. And yes, sometimes a good nap can help.
  • 80% of all human memories are determined by what we see.
  • The eyes are the body’s second most complex organ after the brain.
  • One reason we may never make it to Mars: long-term space travel can wreak havoc on astronauts’ eyes.
  • Eye colour is determined by the amount of melanin in your iris.
  • There’s still no successful method of transplanting an eyeball. The optic nerve that connects the eye to the brain is too sensitive to reconstruct successfully.
  • Heterochromia is the (pretty darn cool) condition where your eyes are two different colours.
  • Out of all the body’s muscles, the ones that control your vision are the most active.
  • Babies are born colour blind.
  • Blue-eyed people have a common ancestor with every other blue-eyed person.
  • During major depression episodes, people see less contrast, making colours seem duller.
  • Smoking reduces night vision.
  • Under the right conditions, humans are capable of seeing the light of a candle 14 miles away.
  • It kind of feels like laser eye surgery (a.k.a. LASIK) has been around forever. But the first procedures in the U.S. took place in 1999.
  • Geckos can see colours 350 times better than a human.
