The Human Eye

Look around what do you see? Colors lights and shapes all key It all starts right here in the eye Let's break it down come on let's try! The cornea's clear it lets light in Through the pupil our journey begins The iris adjusts like a camera's guide Controls the light that goes inside Behind the pupil the lens sits proud Focusing near and far it's not too loud Bending light onto the back so precise On the retina a screen oh so nice! the retina a screen oh so nice! The retina's where the magic's at Rods and cones in a cozy flat Rods see in dim cones see in light Colors and shades oh what a sight! Signals travel fast as a spark Through the optic nerve in the dark To the brain where pictures are made A beautiful image wonderfully displayed In the middle the vitreous gel Keeps the eye's shape and keeps it well It's clear and thick like jelly fun Supports the eye second to none! Now you know how your eyes do work From cornea to brain every little perk So cherish the sight and keep them bright With the science of the eye you're seeing right!
