The first structure to intercept light as it enters the eye is the cornea. The cornea is a transparent, dome-shaped surface that covers the front of the eye and plays a crucial role in focusing light onto the retina. It refracts the incoming light before it passes through the pupil and lens for further focusing.
When light enters the eye, it first passes through the cornea, which is the transparent outer layer of the eye. The cornea helps to focus the light as it enters, before it passes through the aqueous humor and then the pupil, which is controlled by the iris to regulate the amount of light that continues into the eye.
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 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?
Pupils "constrict" when light enters, and "dilate "when the lighting dims
The iris has an opening, called the pupil, through which light enters the eye.
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.
