Pretty nearsighted here too, think there might be a correlation. Seems like I read something like that. As I read about other symptoms that go along with VSS I remember it like checking off a list :)
Actually I have a weird, possibly related, question. If you lay in the dark with your eyes closed for awhile but definitely not sleeping, do you see subtle weird flowing colors? It's a thing my brain/eyes do that I've always thought was related to the VSS but rarely had a chance to ask anyone who might share it.
