As a very nearsighted person, I can see bokeh if I take off my glasses and look at points of light - either nearby small lights, or far-away large lights. Also, when I look at a bright sky through a tree's canopy, the canopy transforms into a breathtaking mosaic of bokeh, which becomes animated if the tree is swaying in the wind. Can people with normal vision experience this?

I can if I squint. I have glasses, though.

I have good vision, and I can see good bokeh if I focus closer than the objects I see, and bad bokeh if I focus farther than them (which is much easier to do).

finally, an advantage for the near-blind

Not sure what it is I'm doing but intentionally blurring my vision creates a sort of visual bokeh

For me, points of light look like the canonical star shapes you see in telescope photos — which I don’t really understand because from what I’ve read, that effect is due to the braces which hold the telescope’s lens in place.

  That's called a 'starburst' and it happens in human eyes for all sorts of reasons. It's possible naturally and also as a LASIK complication, for instance. Look for 'starburst' here https://visionsimulations.com/ https://visionsimulations.com/ Sadly the simulation site is down because of the new Cross-Origin restrictions on images in canvases but perhaps you can see what it looks like in the preview images on the main page and if you google 'starburst vision'.

Anyone can see what it looks like to be (strongly) nearsighted by putting a magnifying lens in front of their eyes. Anyone nearsighted can estimate the strength of their nearsightedness by looking at an object close enough to be perfectly clear, then increasing the distance until the farthest where it appears clear. Take that distance in meters and invert it. The result is the amount of nearsightedness in diopters. For example : you see clear up to 50 cm away, or 0.5m, you have 2 diopters. You see clear up to 10 cm away, 0.1m you have 10 diopters. Anyone with normal (or corrected) vision can estimate the strength of a magnifying lens by the same method. Most magnifying glasses are 5 to 20 diopters. Well, perhaps not strictly anyone can, but you get the idea.
