Your pupil will dilate in low light and constrict in bright light.
Answer 2
Note that the pupil is just the opening in the iris. Strictly speaking, the iris contracts and so the pupil gets smaller.

∙ 14y agoWell, dilated pupils happen when it is dark, so they get bigger to absorb more light. They also contract in the day. They do that to take in less light, if it bright out. Have you ever gone to the restroom in the middle of the night and turned on the light? Then you come out and everything is very dark? Well see your pupils contract to the light in the restroom, and when you come out, they are small, they adjusted to the bright light. Have you ever been inside all day then you go out and your eyes hurt? They do that because you are in a dim room. So your pupils dilate to take in more light. Then you go outside and there is a lot of light. Get it now?

Is the response of your pupil a reflex or a voluntary action?
The constriction of pupils in response to bright light is called the pupillary light reflex. If the light is shining directly into one eye, then the pupil in that eye will constrict (a direct response), but so will the pupil in the non-illuminated eye (a consensual response).This reflex involves two cranial nerves: the optic nerve, which senses the light, and the oculomotor nerve, which constricts both pupils. It is considered involuntary since you don't think about it.
What structure changes its shape to focus light at the back of the eye?
The lens of the eye also called the crystalline lens.
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.
What is the color portion of the eye?
The pigmentation of the eye's iris and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. The iris, irides, and/or irises is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupils and thus the amount of light reaching the retina. "Eye color" is the color of the iris, which can be green, blue, or brown. In some cases it can be hazel, which is a combination of light brown, green and gold, grey, violet, or even pink. In response to the amount of light entering the eye, muscles attached to the iris expand or contract the aperture at the center of the iris, known as the pupil. The larger the pupil, the more light can enter.
How does the iris control how much light enters the eye?
The iris is the coloured membrane in the eye that controls the amount of light entering the eye by expanding and contracting. The pupil is a hole in the centre of the iris. By expanding, more light will enter the pupil and by contracting less light will enter the pupil.http://en.wikipedia.org/wiki/Iris_(anatomy)
What is the consensual response when a light is shone in eye?
Your eye dilates
Is the response of your pupil a reflex or a voluntary action?
The constriction of pupils in response to bright light is called the pupillary light reflex. If the light is shining directly into one eye, then the pupil in that eye will constrict (a direct response), but so will the pupil in the non-illuminated eye (a consensual response).This reflex involves two cranial nerves: the optic nerve, which senses the light, and the oculomotor nerve, which constricts both pupils. It is considered involuntary since you don't think about it.
Can you see your Eye Pupil get big and then small then so on?
Yes, you can see your pupil get bigger (dilate) and smaller (contract) in response to changes in lighting conditions. The pupil dilates to allow more light into the eye in dim environments and contracts to restrict the amount of light entering the eye in bright environments.
Which structure of the eye changes the direction of light?
The most imortant part of the eye that changes the direction of light is the LENS, though the cornea does do a little of the inital focusing.
How is the aperture of the camera like a pupil?
Because its diameter can be changed to alter the light level on the sensor behind it. In a camera this is done by altering the f/number. In the eye it occurs via an automatic physiological response.
What cranial nerve controls the response of the illuminated eye?
If the light is shining directly into one eye, then the pupil in that eye will constrict (a direct response), but so will the pupil in the non-illuminated eye (a consensual response). This reflex involves two cranial nerves: the optic nerve, which senses the light, and the oculomotor nerve, which constricts both pupils.
Eye vision changes color in different light?

Why every human being has black cornea in his eye?
The cornea is transparent. It is the top layer of the front of the eye. The black part of the eye is called the pupil. The pupil is actually the clear passage through the lens of the eye and appears black because there is no light coming back out of the eye cavity. The pupil changes in diameter as the iris dilates due to the volume of light present in the environment. The iris acts as a shutter to control the amount of light that reaches inside the eyeball.
What is the name of the dark part of the eye that changes its size to let in light?
The pupil absorbs light.
Light shown into the eye will result in a decrease of the papillary diameter which nerves are involved in this reflex?
oculomotor
As the frequency of light changes the human eye recognize a change in?
Color. (British eyes observe changes in colour.)
What is the response of left and right pupil when light shined into the left eye?
its pupil does not react thus not affecting the night vision of the right eye
