Thanks, I had not heard of that one. As a recovering philosophy bro I love cataloging all of these peculiar artifacts of our visual experience. They turn out to matter quite a bit in some of the endless mind versus brain and mind versus matter debates. Off the top of my head:

- Blind spot where the optic nerve exits the eye

- Saccadic Suppression (new to me!)

- Panum's fusional area (how close the overlapping images of your eyes have to be to each other to get merged into a unified image)

- The wagon wheel effect

- trichromatic vision (obvious but important because it easily could have been different)

- The foveial field, the central part of vision that's extremely precise, while things increasingly further away from it are blurry

- specialization in peripheral vision, (eg better sensitivity to starlight, as well as better sensitivity to flickers and motion)

Add those all up and you get a bunch of specific but contingent properties of visual experience. Some people of a certain philosophical frame of mind like to imagine that we inhabit a kind of pure mental experience detached from the physical world, but even if you think you're making no assumptions about the empirical world, all of these contingent facts show up, which make a lot more sense as being the products of biological structure.
