Can VSS be acute and triggered by eye tiredness/dryness?

VSS seems to be the closest to what I've experienced, all though its not a great match.

I get pretty extreme visual snow and "afterimages", like to a degree where 70% of my vision is covered in persistent, flashing "afterimages" distributed randomly in both the center and peripheral view. It comes on suddenly, reaching peak effect in around 10 minutes and then it goes away gradually within an hour or two. This has happened 4 times in total with months in between and my eyesight is perfectly fine in between.

Now I say "afterimages" with quotation marks because they just look like afterimages but aren't actually caused by looking into anything bright, the last time I had this, I had just woken up and was in a dark room.

Each time this has happened, I've been quite worn out, either from staying up for 30+ hours or only getting a few hours of sleep. It is always accompanied by a sensation of very dry eyes. It seems to be present in both eyes at the same time but the functional vision of each eye is affected in a different pattern and usually its worse in one or the other, correlated by how dry each eye feels.

Using eyedrops seems to make it go away faster, basically as soon as my eyes don't feel dry anymore, it only takes a few minutes for the sight to return to normal too. While its happening, my eyes look normal and pupils dilate and contract normally to match the lighting conditions.

From what I understand, VSS is more of a neurological thing? Mine doesn't seem to fit that well given how closely it seems to be tied to the physiological state of my eyeballs. Then again, from the descriptions of various visual issues, VSS seems to be the closest match.

Does this fit? Or has anyone come across something else that fits?
