I've had "visual snow" since forever, but it's very mild, and more acute when light exposure delta is high (e.g. turn on/off a light). I suspect it's because I also suffer from migraines, which started around puberty, though I think it's at least partly genetic because both my mom and my sister also get them. I used to get a very bad one at least once a week, as in, couldn't even get out of bed. Since I started drinking coffee (late 20s), it helped my migraines out tremendously. My migraines (which is a condition closely related to seizures) are partly why I've always said "no" to any form of psychedelic substance; just seems needlessly dangerous.
