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.
This is the dumbest thing I've ever read. Holy.
What do you think makes vision blurry under water?
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
We see a blurry mess underwater because of the particulates in the water. Fish don't see a blurry mess when they look through air.
People being clueless is not my worry.
...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.
"Same effect" what effect? H2O has no special impact on vision. The gaseous atmosphere likewise has no effect on fish's vision. Why the hell would either of these solutions affect vision? They're essentially invisible. Have YOU ever opened your eyes in crystal clear water? You can see extremely far.
This entire thread is confused. What makes it difficult for land dwellers to see underwater also affects those animals that live underwater. The particulates and lack of light.
There is absolutely zero scientific basis for any of the ideas you're offering.
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:
I contest the idea that vision innately becomes severely blurred when submerged. I've swam in crystal clear water, you can see far and with clarity.
And even if the concept you introduced was taken at face value, how is that supposed to address my original point that fish can see out of water? The cornea theory enhances my point, somehow.
You're certainly confident
Arrogant, even.
