it gets bigger
The choroid layer in the eye has a black color pigment on it. Also, the light entering the eye is not reflected because light rays entering the pupil are absorbed by the tissues inside the eye.
Because light is being reflected from the surface. If you paint a room black, light will be absorbed by the black and the room will be dark.
The pupil does not absorb anything, it transmits light energy to the retina at the back of they eye, the retina does the absorbing. It certainly does not emit anything either, though aliens in scifi films can have glowing eyes! Some animals like cats have reflective eyes, but they are not emitting light, only reflecting incident light.
Light colors reflect and dark colors absorb.
A double pupil is a condition a person may be born with. There is a smaller pupil or opening adjacent to the normal pupil. It is still located within the iris and does not affect one's vision. This in old times was known as a "witch's eye". Thank you, Matt E.
They become bigger and widder
They die.
Your pupil expands in the dark in order to obtain more light.
Your pupil expands in the dark in order to obtain more light. Your eyesight is interpreted by the brain with light signals, when it is dark your pupil expands to grab as much light as possible.
If the pupil of the eye did not work, than your eye could not regulate light entering it.
Nothing. AFTER the light is detected and calibrated, the pupil may change size.
When a light is not shined into an eye the pupil contracts gets bigger because the eye needs all the light being presented to it. If the light is not taken away the pupil does not dilate. PS like the eye gets smaller in the light.
No; the change in the size of your pupil is an involuntary action, meaning that it happens without you thinking about it. The size of your pupils adjust to stimuli, such as bright light. If a bright light was shined in your eyes, your pupils would get smaller in order to let as little light in as possible. Reversely, if you're in a dark room, your pupils will get bigger to let in as much light as possible.
in bright light the pupil shrinks
Your pupil gets smaller and larger depending on the amount of light present. in a dark room, your pupil will get big to collect as much light as possible, so that you can see. When you look at the sun or a bright object (which you shouldn't) your pupils get smaller because they have too much light.
Light causes the pupil to constrict in bright conditions to reduce the amount of light entering the eye, and dilate in dim conditions to allow more light to enter. This pupillary response is controlled by the autonomic nervous system to regulate the amount of light reaching the retina for optimal visual functioning.
Light Pupil Dilate was created in 2001.
