another thing...

In spite of the progression of possible causes I’ve been presented with, I’m inclined to believe the last. This is because it matches my own self-diagnosis back from when my symptoms started getting worse last weekend: optic nerve damage. That’s what I was experiencing felt (and feels) like, from the way my visual perception is operating; like data loss or noise post-transducer, not distortion or filtering inside my eyeball itself. I even Gooled for it, without success as I didn’t then know what terms to actually search for.

I should trust myself more :)
