Strange spots in peripheral vision

I’ve had this going on for a few months or possibly even a year or so I haven’t kept track well however I get these smallish spots in my peripheral vision that look like and afterimage of looking at a camera flash and they seem to linger for a few minutes then go away and I’ll get another one somewhere else soon after and they seem to appear more when I’m actively thinking about them however they still show up sometimes even when I’m not thinking about them. It seems it matches some peoples symptoms here however most other people have been describing the spot to stay for days or weeks and that’s just not the case for me.
