When your pupils get bigger do your irises get smaller?
No, when your pupils get bigger (dilate), your irises do not get smaller. The iris is the colored part of the eye that controls the size of the pupil. When the pupil dilates, the muscles in the iris relax, allowing the pupil to expand, but the overall size of the iris remains the same.
Which part of the eyes control size of the pupil?
The iris, specifically the muscles within it, control the size of the pupil. Contraction and relaxation of these muscles regulate the amount of light entering the eye by adjusting the diameter of the pupil.
What is dark round opening at the center of the iris which becomes smaller or bigger?
That is the pupil, which is essentially a hole in the iris that allows light to enter the eye. The pupil can change size in response to different lighting conditions and levels of arousal.
What is The difference between pupil and iris?
The iris is the coloured part of the eye. It's typically brown or blue, but other colours like green or grey are possible. The pupil looks like a black dot in the centre of the iris. It can dilate (get wider) and contract (get smaller). The size of the pupil changes depending on how bright the light is. If you are in a very bright room, or in bright sunlight, your pupils will be very small. This is because not much light needs to be let in to the eye for it to be able to see well. In a dimly-lit room your pupils will be bigger, to let as much light into the eye as possible.
