10The human eye is an optical instrument.
Cornea refracts less light than the lens.
Pupil allows light to enter the eye.
Iris controls the size of the pupil.
The eye lens is concave.
Ciliary muscles adjust the thickness of the lens.
Rod cells detect color.
Cone cells detect color.
The optic nerve sends signals to the brain.
The brain inverts the image formed on the retina.
