How to overcome a fear of deep water?

[AptaMer]

sharks have bad eyesight

Just wanted to say, SeaMonkey, that most sharks can see rather well. Their eyes are adapted for seeing in low light conditions (i.e. in deep water) at the expense of being able to focus and see detail well.

They can see in 10x lower light conditions than humans can, but can't see detail as well.
