Parts of the eye is the retina, cornea, sclera, iris, pupil, and lens.
I heard that the Iris is the black dot in your eye, and it gets bigger when there is less light, and smaller when there is more.
Wow! Thanks for teaching us about human eyes!
Light comes into the eye, and focuses through the lens. Then it shines on the retina where rods and cones determine colors and helps you see when there is little light in an area. Then the optic nerve sends a message to the brain to determine what an image is.
