7 Freaky Facts About Your Eyes

The human eye is one of the most important parts of the body. They see the world in ultra high definition. They are the “windows to the soul.” They are more than meets the… well… eye. Humans heavily rely on sight, but do you really know what’s going on in your sockets? Crazier things than you realize happen right in the middle of your face. Blink and you’ll miss them!

1. The eye is always making “microsaccades”, or slight jerks, to ensure that images don’t fade from your vision.

I didn’t know a single one of those facts. (And I’ve had my own eyes for 30+ years.) Who knew I grew such amazing works of technology, or that I was so lazy about reading their “instruction” manual?
