Don’t underestimate your eyes: vision is the most important of all of the five senses, and the eye is one of the most complex organs in our body. Our eyes allow us to see the world around us, form connections and make memories. So, how much do you really know about your eyes and how they work?

Here are a few interesting facts about eyes:

  • 80% of our memories are made based on what we see.
  • You know that annoying ‘red eye’ we see in photos? Red eye happens when the light from the flash of a camera bounces off the back of your eye, which is filled with (you guessed it) red blood vessels. This causes your eyes to appear red in colour in the photo. Gross, or fascinating?
  • Think love is complicated? The eye (not the heart) is the second most complex organ in your body after the brain.
  • Eyeballs are bigger than you think. Only 1/6 of the human eyeball is actually visible.
  • We can only see 3 colours: red, blue and green. Any other colour we see is just a combination of these colours. Crazy, or what?
  • Your eyes can get sunburned (and it hurts like crazy). Wear sunglasses that protect against UVA and UVB rays. Repeated sunburns can cause your eye tissue to thicken, which can lead to all sorts of not-so-fun problems.
  • 20/20 vision isn’t actually ‘perfect’ vision – it means your vision is average, or you can see what an average person can see at 20 feet.
  • If you have blue eyes, you share a common ancestor with all other blue-eyed people across the world. (I’m still hoping this means I’m a Princess). The first person who had blue eyes lived between 6,000 and 10,000 years ago. Before this, everyone had brown eyes.
  • The most active muscles in your body are your eyes. The eye has over 2 million moving parts!
  • Do eyes creep you out? You might have ommatophobia, or a fear of eyes.
