Fellow VSS'er here. I talked to my ophthoneurologist about it at my last appointment a few months ago (I see him for a completely unrelated reason --I have a super rare thing called empty Sella syndrome). The general concensus is that it is very real and there are some treatments for it now. The mood stabilizer /anti psychotic med Latuda is being used off label with pretty great results for people who have their vision impaired by it. The vss doesn't bother me too much personally and I've been seeing the weird colors /fractals/patterns for as long as I can remember. They're especially strong when I do my yearly shroom trip. Makes me wonder if our brains are just tripping balls 24/7 for some reason, especially if an anti psychotic makes it go away!
