When you rub your eyes, you are putting pressure on your eyes. The small lights/shapes you see are a response your eyes are giving are because of the pressure of your hands. The not so eli5 word for these lights is “phosphenes”.

It can be a lot of things.

On the surface of your eyes, you have some tiny veins that can sometime be clogged by a white blood cell. you only see the red blood cells that are stuck behind it, and only when you look at certain blue surface.

then, there is a liquid called aqueous humor that can sometimes coagulate forming those translucid weird worm that you can see when you look at something bright (the sky, a white wall, your computer screen,…)

Then, you have a lens that can be deformed or hurt. In that case, your whole vision can be altered, but that might be one of the cause of those shapes that you see: you hurt your lens a bit and it takes some times to gain its original form.

You have the retin afterward, that can be hurt too and that could cause you to see some form of aberation like the circles you are mentionning

Or it can be your optic nerve that has been moved in a weird way that causes it to give false information to your brain

And finaly it could just be your brain that don’t manage to make a proper picture. this one is not very likely, but if the problem comes from your brain, then it’s pretty bad.
