The apparent failure to mirror "correctly" left and right in this illusion reminds me of a great interview question I heard: why does a mirror reverse things left and right, but not flip them top and bottom?

It can be fun to watch people scratch their head over it.

The interviewer took it from Feynman:

I'm afraid Feynman's already spoiled the answer for me.

Easy enough for anyone with eyes to see the obvious explanation.

Are you implying _two_ eyes? Because if you think that's the reason, just try closing one eye and looking into a mirror and you'll see that nothing's changed.

(Also, as an exception to your statement, I have eyes, and I wasn't able to grasp why it happens until I watched a video about it.)
