What i mean is they can’t see well while out of water, just like we can’t see well when we’re underwater. Our eye evolved to see above water, so when we try to see underwater, the water will mess up the light going into our eye, so everything would be blurry for us. The reverse is true for fish as well. So while they poke their head out as if they trying to take a peek, what they most likely see is blurry mess.
Go dunk your head! Seriously, you can see the effect in a pool - look at how well you can see things above and below the surface, go underwater, and open your eyes. Things will be fuzzier.
You’re trying to reason away an effect that people actually see, and that you can verify independently. That’s the opposite of how science works.
For a scientific explanation, my first Google got came up with this - an article about some kids who do seem to see normally underwater. It also includes this explanation for our blurrier experience:
When the eye is immersed in water, which has about the same density as the cornea, we lose the refractive power of the cornea, which is why the image becomes severely blurred

What makes you think fish and human eyes didn’t evolve for their environment?
Lol, considering how they are right, I am wondering what you think makes vision blurry underwater

…so what happens when you use goggles? Or a camera?
Lakes can be dirty, but you can see the same effect in a pool. Or your bathtub.
