The eye is adapted for vision in a dimly lit place because of the pupillary light reflex, which adjusts the amount of light that reaches the retina. The eye takes approximately 20-30 minutes to adjust from bright sunlight to complete darkness.

Why do eyes need bright and dim light?
Eyes do not need bright and dim light - although the iris (colored part of the eye) and pupil (black center of the eye) function differently under these circumstances. In bright light, the muscles in the iris contract to make the pupil smaller. In dim light, the iris makes the pupil enlarge to allow as much of the scarce light as possible.
When a light is in your eye does you pupil go bigger or smaller?
Smaller because the eye is protecting it's self from the light
Why objects in dim light are seen more clearly from the corner of the eye?
because the iris allows you to see in dim light
What part of the eye allows light to enter?
The pupil is the part of the eye through which light passes.
How is the Nerve impulse responsible for the pupil becoming smaller?
Pupil is a window for the light to enter our eyes. When we are in a dim light a nerve impulse is generated to the brain to enlarge the pupil. Size of pupil is managed by the iris (coloured part of the eye). If excessive light is there, the pupil shrinks to a smaller size so that the eye's not damaged esp. the retina where the image of objects are formed
What part of the eye is sensitive to dim light?
the pupil
What part of eye makes the pupil smaller in bright light and larger in dim light?
Iris

What receptor of the eye functions best in dim light?
rod ;)

because the iris allows you to see in dim light
Why do objects tend to look black and white in dim light?
Because the cells in the retina of your eye that produce the sensation of color are insensitive to dim light, and images in dim light are perceived by other retinal cells that are less interested in color.
What part of the eye is filter protection?
The eye is protected by a clear film called the cornea. It also helps focus the light.
What controls the light going into eye?
The pupil controls the amount of light that enters the eye.
Would your eye sight damage if you read under a dim light?
Yes, but "eye" do it anyways. (Badum, crash)Reading under a dim light can hurt your eye and cause you to strain to see (like I am right now) so you better not do it!FACT: THERE IS A GARFIELD STRIP ABOUT THIS! I SUGGEST YOU READ IT!
Why is the part of your eye excluding pupil white?
The white part of the eye is called the sclera. It is made up of tough connective tissue that helps protect and support the eye. The sclera is white to provide a stark contrast against the colored iris and pupil, which helps with light reflection and vision.
Does the pupil absorb the light?
The pupil is actually the absence of the iris (colored part of the eye), so it only allows light to pass through it and helps control how much light passes to the back of the eye.
