some species (invertebrates, arthropods and certain fish etc.) see in Polarized vision. I’ve seen images but how does it work and what are the benefits of it?

I think it depends on their environment that they live in. The species evolved those eyes to make it easier to protect themselves from predators. Or atleast i think so. Im not sure about how it works tho

Reflections changes the polarization of light. So it is easier to distinguish reflected light from direct light. You can even buy polarized sunglasses which will give you the same ability. It makes it much easier to for example look into water because the sunlight that is reflected off the surface is filtered away.
