yep, if you only consider visual acuity & image resolution in daylight the only animals that surpass humans are some birds of prey. Our vision is that good.

>Varies greatly depending on the animal. I hear squid have the best eyes in the whole of the animal kingdom.
cephalopods are all color blind but can perceive polarized light. And cephalopods are good at still seeing in low light conditions but see rather low resolution images compared to humans. And they also have tiny primitive brains that can't perform complex image processing like ours can.
The Colossal Squid for example has the largest eyes in the animal kingdom but posses a brain that weighs only 100 grams despite weighing half a ton. The large eyes are probably for detecting Sperm whales in the deep black ocean.

>mantis shrinp see "better" in that they can can receive a wider spectrum of colours than us
Mantis shrimp aren't even better at that. Once again they also have atrocious image resolution compared to humans.
I remember seeing a simulated vision for Mantis shrimp and it was a blurry mess.
Mantis shrimp tried to overcome small brains by developing very complicated eyes instead. But they still come up short.
" Since IT cortex has millions of color-tuned cells, they can sample the spectrum much more finely than the 12 mantis shrimp photoreceptors, so interval decoding could simultaneously provide much better color identification and discrimination compared to mantis shrimp, resolving the paradox that mantis shrimp have poorer color vision than humans despite having more photoreceptor classes."

"Colour blindness test surprisingly reveals that mantis shrimp have poor colour sense.
The study from UQ’s Queensland Brain Institute, crushes the illusion that complex eyes with more colour channels mean better colour vision."
