Afaik if you’re myopic, your eyeballs are too long so the plane of focus created by looking at a far away object is no longer on your retina. So i think by looking through a pinhole you widen the depth of field. This means even stuff you don’t focus on is seen sharper.

I wonder if this also works for hyperopia…

  Yeah, but not only our eyes/bodies are weird. If you want to know more about weird eyes look up goat pupils (they have horizontal pupils the can rotate 50% to be always level with the ground) or nautilus pinhole eyes (early stage of our eyes with no lense).

Is this why I can see so much better in VR? Smaller field of view? I always assumed it as kind of a side effect of the depth of field hacks they do but FOV would make sense.
