What's in your eye?

December 2018

The human eye is an amazing organ! Let’s take an in-sight-ful look at what’s actually happening inside your eye. Warning: this article couldn’t be cornea... see what we did there?

The most amazing organ in the body? That’s just how eye roll…

The secret to the magic of the human eye is light. Light bounces off everything around you and then into your eye. It passes through a thin veil of tears, then through your cornea. This clear layer helps to focus light before it reaches the retina.

The retina sits at the back of your eye, and light is projected onto it like a projector.

Lens not get bogged down in the science!

Curved corneas mean the human eye actually can see upside down

There are some amazing facts about the human eye, too. Did you know, our curved corneas mean we actually see the world upside down? Then our brain flips the image the right way up. Isn’t that unbelievable?

Also, having 20/20 vision just means you can read a chart from 20 feet away in normal lighting. It’s possible to have 20/10 vision, which means you can see at 20 feet what most people can only see at 10 feet – quite the spectacle!
