From [this thread](http://www.straightdope.com/classics/a3_041b.html), it didn’t really go into much detail about why physical exertion may cause these little moving stars in ones vision. I’m only 26, so probably not close to retirement in anyone’s books at the moment.

Why does physical exertion cause them?

I see them occasionally after I sneeze.

I get them occasionally after running up a flight of stairs, are they caused by a drop or rise in blood pressure?
