Swimming Under Water With Eyes Open
Technical question. How are they swimming under water with their eyes open? They are in the ocean; hence sea water. I tried that once in the ocean. My eyes stung like hell. Eyes open in a regular pool sure. My eyes stung a little because of the chlorine. But nothing like sea water.
I have seen this in other movies as well. O.K., so maybe the "actors" are wearing contacts; but the characters are not.
You cannot open your eyes in sea water like they did.
