phosphenes

Hey! Anyone sees two black dots when moving ur head up and down or to the left and right? Theres not so many infos about this online but from what I read it is visual snow related. I have to say I got my eyes checked because of this and the results came out perfectly! I couldnt enjoy my vacantion because I kept seeing them when moving my head, I tend to think they get worse when I am not having enough sleep. But theyre always there when I make head movements. Though I have health anxiety and everything stresses me out, I just wanna know I am not alone! Thanks
