You've all grown up knowing that you have an eye, two in fact! You never learned much about the eye in elementary school, but you sure will/did in middle school! Today's topic (question) is...: How does your eye direct light into the eye and then transfer it to the brain? Well, your eye has a tiny little hole called the pupil. The pupil is covered by your cornea which is just like a window, it's clear but blocks the rest of your eye. The pupil focuses and bends light so that means when things get really bright, your pupil tells the lens (which is farther back behind it) to get smaller. When things get dark your pupil tells the lens to get bigger. 
     After light passes through the pupil, light passes through the lens (so it can be adjusted). Then it goes into this jelly-like substance called the vitreous humor. Then the retina, where nerves take the light to the optic nerve which is a tunnel to the brain. I know it might sound confusing but with some research, you'll get it. Search "eye diagram" on Google Search and look at images for more information. It really is amazing how the eye and light work!
