Yes. ALL lovers should have noticed this.
Nothing. AFTER the light is detected and calibrated, the pupil may change size.
Yes, pupil size should not be affected by the focal distance, unless there is a change in the amount of light at that distance. To change focal distance, the lens contracts or expands. The pupil dilates and constricts based upon how much ambient light there is.
The size of the pupil in the human eye is controlled by the iris, which is a ring of muscle that can expand or contract to adjust the size of the pupil.
There is one pupil in each eye. The pupil is the opening in the center of the iris that allows light to enter the eye. Its size can change depending on the lighting conditions to regulate the amount of light entering the eye.
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.

The opening hole of the eye is called the pupil. It is the black circular opening located in the center of the iris that allows light to enter the eye. The size of the pupil can change in response to different lighting conditions and emotions.
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.
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.
