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.
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.
The iris has an opening, called the pupil, through which light enters the eye.
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"

The iris is the part of the eye that adjusts in response to light conditions. It controls the size of the pupil, which determines how much light enters the eye. In bright light, the iris contracts to make the pupil smaller, and in dim light, it dilates to make the pupil larger.
That is the correct spelling of translucent, meaning allowing a diffuse passage of light.

the retina! where else, it burns it and riuns your eye
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 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
Behind the cornea and in front of the lens is the iris, the circular pigmented band around the pupil. The iris works much like the diaphragm in a camera, widening or narrowing the pupil to adjust to different light conditions.It is made of sphincter and dilator muscles of the pupil.
