There’s a number of things that can cause that.

Floaters for example, can get stirred up when changing aspect perhaps you’re seeing those.

If it’s defined black dots it can be blood in your eye, which could have a myriad of causes.

You could also have pre-diabetes so should probably have your blood sugar checked.

Not everyone has that.

In addition, if you’re seeing stars, you could be having a large pressure shift in your body due to a heart issue like AFib or a left ventricular issue.
