Seeing Visual Snow is not the same as having Visual Snow Syndrome. Many people see visual snow when they do things such as rubbing their eye, transition from a light to dark place, etc. Visual Snow Syndrome is a more long term, MONTHS at a time to permanent experience. I hate to come across as dismissive, but please refrain from self-diagnosing unless you have talked to a doctor or have done extensive research from peer-reviewed sources.
I also just figured out what Palinopsia is too. I’ll post on that later if I remember too, but it’s when you wave your hand and there is a trail behind it. It only happens to me when I’m tired but I would wave my hand in front of my face because I thought it was cool (I still think it is). Apparently there is a link with palinopsia and migraines which is crazy because I used to have bad ones and they run in my family.
Ok, but I dont think you realize you're encouraging people to misdiagnose themselves. Visual snow is common, VSS (a chronic condition) is rare. Again, I hate to be ~like that~ but I feel like you're encouraging people to say "Hey, I have [blank extremely debilitating syndrome]" because they temporarily experienced a symptom of it.
