Is the amount of light allowed in the eye regulated by the pupil?
The lens and the pupil of the eye are two independent parts. The lens focuses light onto the Retina, and the pupil regulates the amount of light entering the eye. So, if the light intensity changed while you were focused on a particular object, the size of the pupil would change, but the lens focus would not.
What Is the part of the eye that contracts and dilates to adjust the amount of light entering the pupil.?
IrisThe colored part of the eye which helps regulate the amount of light entering the eye. When there is bright light, the iris closes the pupil to let in less light. And when there is low light, the iris opens up the pupil to let in more lightLensFocuses light rays onto the retina. The lens is transparent, and can be replaced if necessary. Our lens deteriorates as we age, resulting in the need for reading glasses. Intraocular lenses are used to replace lenses clouded by cataracts.CorneaThe clear front window of the eye which transmits and focuses (i.e., sharpness or clarity) light into the eye. Corrective laser surgery reshapes the cornea, changing the focus.
How does the iris adjust to the amount of light that enter he?
The iris is a muscle located behind the cornea of the eye. It adjusts the size of the pupil to control the amount of light entering the eye. In bright light, the iris contracts to make the pupil smaller, limiting the amount of light that reaches the retina. In low light, the iris relaxes, making the pupil larger to allow more light into the eye.
What is the function of pupil in eye?
. The pupil is an adjustable opening that controls the intensity of light permitted to strike the lens. The lens focuses light through the vitreous humor, a clear gel-like substance that fills the back of the eye and supports the retina

What does it mean you when you a large eye?
When more light is shined into an eye, the pupil shrinks so that let light is taken in and you have less chance of blindness.When less light is seen by the eye, your eyes become larger to take in as much light as possible.If your actual eyeball is expanding, then I suggest requesting a doctor, for this is a sign of hyperthyroidism.
Why have you got a halo around your pupil?
In your eye? That is the iris (not a halo). Your iris is actually a sphincter (a circular muscle) and it will expand or constrict to control how much light is let into your eye. That is why in dim light your pupil will be really big, because it is opening wide to try to let in as much light as possible so you can see better.
