I only have EYES for you

The eye is an amazing machine. It lets you see, both in color and in the dark, by sending messages to your brain. It has a cool process for letting you see, too. First, the light goes through your cornea, through your pupil and into your eye. The iris controls how much light is allowed into your eye, so that you don’t get blinded. Then, the light passes through the vitreous humor and hits the retina, which sends a message to the brain through the optic nerve. That’s when you see.

I took this photo of my eye with my computer, then filtered it through a photo editing program called pixlr express and added captions.
