Optic nerves
Light rays enter the eye through the cornea.
The retina
The pupil controls the amount of light that enters the eye.
The curved surface of the cornea turns light waves inward toward the lens (a sturdy tissue inside the outer eye) which focuses light on the retina at the back of the inner eye.
The steps of light being received by the eye are: generation of light passage of light to the eye through the tear film through the cornea through the aqueous humor through the lens through the vitreous humor through the layers of the retina to the photoreceptors of the retina
the iris
Pupil.
Lens
As light enters the eye, it passes through the cornea and the lens and is eventually focused onto the retina.

The retina
As light enters the eye, it strikes the receptor cells of the retina, called the rods and cones.
the retina! where else, it burns it and riuns your eye
lens
The eye uses both the pupil and iris to control how much light enters the visual receptors. here is a source to read more: http://www.biologymad.com/NervousSystem/eyenotes.htm
Light bounces off the leaf, enabling the eye to detect its color and shape as light also enters the retina.
