ELI5: Why do insects have much better vision than humans, despite having smaller eyes?
gpt
Depends on how you define “better”

Insects have compound eyes that have evolved a number of functions that human eyes don’t have.

Dragonflies have nearly 360 degree vision.  Bees can see near-UV light.  Moths can see in very low light conditions.

What they *don’t* typically have is depth and focus.  Human eyes have a very different design and are built to track the 3D location of a single object.  We do this incredibly well, and your visual distance and clarity blows away that of any insect.

You can’t see a full sphere around you at all times, but a dragonfly can’t focus on objects more than a few meters away.  Insects live in a very small visual world.

And that’s just the best of them, many have terrible vision.
