Only seen a few videos there but they all seem to have a distinct-but-not-fully opening and closing of the eyelids happening at the same time - when the eyelids close, the pupil grows; when they open, it shrinks.
Which suggests a certain amount of autonomic reaction to changing light conditions rather than controlling the pupil itself? I guess you'd have to demonstrate it without any eyelid movement to control for that.

These sorts of quirks indicate to me that we may have much more conscious control than we assume.

Wow that was awesome and so easy to do.
That is very interesting. I have just been to some clinics to get examined for laser eye surgery and found that I am not a good candidate because my pupils get too big at night.
I wonder if learning this skill could fix that.

Huh, I this is something like raising one eyebrow. A lot of people can do it, not everyone. I can do this, but never thought anything of it.

I also do it to relax mysef or to dig deeper in my thoughts
