Light enters the eye through structures in the following order
cornea>pupil>lens>retina
The retina is made up of several layers of cells, in the following order: ganglion cells, amacrine cells, bipolar cells , horizontal cells, photoreceptors.
Thus light passes through 4 cell layers in the retina before hitting the photoreceptors (rod and cones), which initiates the process of vision. Notice that all the structures light encounters before hitting the absorbing pigments in the photoreceptors are completely transparent to visible light, but not necessarilly to infr-red or ultra-violet light.

∙ 11y agoWhen light enters the eye it must pass through the cornea, the aqueous humor surrounding the lens (anteriorly and posteriorly) or front & back, the vitreous humor within the globe of the eye, and finally makes connection with the fovea centralis of the retina, which is then converted to an electrical signal and sent to your brain, allowing you the perception of sight. :-D

cw: That is a trick question, because the light bounces off the back of the eyeball to excite the rods-cones. The cones face "backward" (so to speak), etc. BTW, the retina has cones, etc.

What do eyeglasses do to light before it enters the eye?
bend it They bend the light so that the cornea and (eye) lens may focus the light on the retina.
What does the comea do in your eye?
The cornea is responsible for focusing the light that enters the eye. It is the transparent portion of the eye that covers the front of the eye
