Neat optical illusion

Explanation of this relatively new optical illusion.

This illusion, new to science, is strong enough to trick our reflexes - Science & research news | Frontiers

By Mischa Dijkstra, Frontiers science writer An illusion new to science shows that the pupillary light reflex, which controls the width of the pupil in anticipation of expected changes in light, depends on the perceived environment rather than the physical reality. Have a look at the above...

Reminded me of an article I read recently: https://www.scientificamerican.com/article/how-the-brain-constructs-the-outside-world/

I like this one:

Put your mouse cursor on an edge just to see they don't move, get bigger or even shift.

Yeah I like that one. Just reminds you seeing shouldn't always be believing, but we all do.

I see just a hint, then it stops. Must be a 14%er ... or is it extra subtle?

This one isn’t subtle for me, but the mechanism (out of phase inner and outer borders) is straightforward. It’s a decent analogy for phase effects used to enhance stereo image (ironically, people like to use it to ague the opposite, not knowing how it works).

I've always liked this one. Focus on the plus sign in the middle. See that rotating green dot. Well there is no green dot. They just blank out the pink one leaving the gray background. For a moment you eye sees green.

Negative colour afterimage (explained by opponent process theory) is also straightforward. The first one is your best so far (even if it doesn't work for everyone).

Does not work on me, I wonder why.
There is a whole site of these.

Love this one, very effective.

This is similar to the 1st one.

Oh wow, that is really messed up.

I can never trust my eyes again.

How about this one?

The pieces are the same brightness.

Same with 'A' and 'B' on this one:
