So I've been posting about symptoms I've experiencing and no one really knows what is wrong, so I've been experiencing symptoms of visual snow, such as halos and starbursts and entoptic phenomenon, and even afterimages to an extent and I think I caused it but I don't know so this is what happened, a while ago I read an article on the internet that said if you roll your eyes back and forth about ten times it exercises them and will strengthen your vision, well I started doing that on a daily basis and these symptoms started popping up, needless to say I stopped, so I am pretty concerned that I caused this by doing that but I'm not sure so I geuss what I am asking is, is it possible to damage your eyes by rolling them like I was? An opinion from a professional would be nice. Thank you for reading this!
