after pupil first light enters aqueous humour or pupil
Light first enters the eye through the cornea, the clear outer covering of the eye that helps to focus light. The cornea then bends the light and directs it through the pupil, the black hole in the center of the colored iris.
The biconcave structure is the "lens, but his focuses the light, it does not adjust for the amount of light. The structure that adjusts for the amount of light entering the eye is the "iris"
It is only possible if light enters another medium with an angle other then 90. WHen it does so then some part of light enters the medium first and it slows down first while the other part enter after a while and slows down later. This time gap .For much better understanding see... http://www.youtube.com/watch?v=Tyzci1qTVL8
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 translucent structure where the light enters eye is called the Aqueous Humour. The entire Eyeball it's self is covered by a thin clear layer called the Sclera.

what happens when light enters a polorizing filter?
The structure that allows light to enter the eye is the pupil. It is the circular opening in the center of the iris that can dilate or constrict to control the amount of light entering the eye.
Pupils "constrict" when light enters, and "dilate "when the lighting dims
The iris is the structure in the eye that gives it color. It is a thin, circular structure that controls the size of the pupil and regulates the amount of light that enters the eye. The amount of pigment in the iris determines the color of the eye.
