For a human, when diving underwater, everything is blurry because of the waters'water's different refractive index compared to that of air, which we are accustomatedaccustomed to. How do animals, like turtles, seals or penguins, handle that difference when changing the medium? areAre they nearly blind at surface and can focus underwater or the other way around? canCan they adoptadapt to different refractive indexes on the fly? howHow?
