And for fun, here's wikipedia's example of the blindspot. Stare at L with only your left eye, adjust the distance, and the R will disappear. You don't see "nothing" or "black", you see the background, because you expect to.pic.twitter.com/NBN485EOvC

BTW, remember how I said "vertebrate eyes" up there? Guess who has eyes which are wired forwards instead of backwards (no have no blindspot), have an internal lens, and can even see polarization of light? our good friends the Cephalopods!pic.twitter.com/SOMT5CB2SY
Finding this fascinating as I have an adult son with Lowe Syndrome. Born with bilateral cataracts, taken out, occasionally uses +25 contact lenses, has pendulum nystagmus, microphthalmia and CVI. How does nystagmus affect saccades, how does his brain "see?"

I did a ton of research into deja vu, because it happens to me a lot. Turns out, scientists think deja vu is related to how our vision and brain interact. By the time we're mentally processing an image, we've already seen it.
Most of the time our brain time stamps it as "happening right now" but on occasion it accidentally time stamps it as "been there done that"
And here's the presentation on Vampires that he did at a SciFi convention. https://www.youtube.com/playlist?list=PL30ED0756E00786E2 … Chewy. entertaining, and, horrific backstory.:D
I had a patient with Charles-Bonnet Syndrome. That shit’s nuts. He had end stage macular degeneration so his brain just filled his vision with hot ladies.
I rate it as one if the best sci-fi novels of recent times. Probably the most recent sci-fi with the most fresh ideas, it's exploration of consciousness from the standpoint that it's rare in the universe and the implications of that was brilliant.
