If considered part of the eye, the lids can prevent most light from entering the eye. Otherwise, the amount of light allowed inside the eye is primarily controlled by the Iris. The Iris surrounds the pupil which is literally a hole. The Iris can make the pupil smaller (constrict) or make it larger (dilate). The larger the pupil is, the more light enters the eye. The muscle movements responsible for contraction or dilation are "automatic" or involuntary.
RE: prior answer of "Retina controls the amount of light let in and let out".
The amount of light reaching the retina affects the Iris. The retina is at the back of the eye and is where light is changed into nerve signals. If those nerve signals indicate that there is a lot of light entering the eye, the iris will constrict making the pupil smaller. The opposite happens if the nerve signals indicate that there is very little light.

Parts through which light passes as it enters the eye?
As light enters the eye, it passes through the cornea and the lens and is eventually focused onto the retina.
Which layer has dark pigment to absorb extra light and keep the inside of the eye dark?
the pupil
The photoreceptor cells are very sensitive to damage from light?
True the Photoreceptor sensory cilia are the light sensitive parts of the rods and cones in the eye's retina
Which parts of the eye help focus light as it passes through the eye?
The cornea is responsible for taking all light rays in and bending and molding them so that we see. the optic nerve sends a signal to the brain sort of a fax system. So there really isnt just one part of the eye that aides in sight.
What is the Response of eye to bright light?
The iris controls the amount of light entering the eyes through pupil. When the surrounding is extremely bright, the iris contracts the size of pupil. This decreases the amount of light entering the eye. This is why when we are suddenly exposed to bright light, the eyes blink and in meanwhile, the iris contracts.
Layer of the eye that keep light from scattering in the eye?
Retina
When light enters the eye what two parts of the eye do they pass through first?
lens
What protects the eye and helps keep the light out?
the sunglasses
What are the parts of the light bulb?
glass, wire, socket, current, and the eye
What protects the eye and help keep the light out called?
the sunglasses

Parts of an eye and its uses?
The white part of the eye is called the sclera. The colored circle in your eye is called the iris. The black spot in your eye is called the pupil. The pupil is actually a hole that gets bigger in the dark so it lets more light in. It gets smaller in the light so it could keep less light out of the eye.
How the parts of the eye's cause light from objects to be seen by us?
when light enters the eye it passes through the cornea then pupil then the lens where it is bent and focused on the retina
Why does color appear?
the material absorbs light, but just those light parts that give the material its colour are reflected and get into our eye
Which best explains the relationship the electromagnetic spectrum and sight?
Visible light and infrared light are the parts of the electromagnetic spectrum that can be seen with the eye.
What is the part of the eye are necessary for seeing?
An eye is a complex structure and essentially all parts of the eye are required for vision to occur. However the part of the eye which detects the focused (by the lens) light image is the retina.
Which best explains the relationship between the electromagnetic spectrum and sight?
Visible light and infrared light are the parts of the electromagnetic spectrum that can be seen with the eye.
