Huh, I didn't know this was something special. I used to swim underwater with my eyes open all the time when I was little and I could see underwater just fine like the article describes. I just assumed everyone could :).
Although I couldn't do it in salt water, it stung my eyes too much but that might also be due to me learning to swim in pools instead of the sea.
