Why do optical illusions cause headaches?

Answer 1

The best answer I can imagine, for you, is that an optical illusion can cause a reaction similar to an astigmatism.

Many optical illusions operate on a change in how you focus on the image. Changing the focus of your eyes requires some very fine muscle movement.

In an astigmatism, your eyes are regularly refocusing, which tires out these muscles. If you look at an optical illusion, and keep switching back and forth between the different images you can see, you are most likely refocusing constantly. Again, you tire out the muscles controlling your eyes, hence a headache.

This is merely theory, so take it with a grain of salt.
