In terms of writing, first person is "I did this" and third person is "He/she did this".
Second person is "You did this" and is very, very rarely used in storytelling mediums because the first and third are far better for this purpose. The only instance of second person I can think of is perhaps in advertising campaigns.
Second person is NOT through the "eyes of someone else", nor is it a "fixed camera view", that is the same as third person if you think about it.
There is no such thing as a second person point of view as it were and a second person game as you seem to be thinking is not possible. The closest thing I can think of is a first or third person role playing game with a voiceover/cinematic narrative referring to the player as "you".
I think this clears this up, but please feel free to ask for clarification/post a counter-argument.
EDIT: Some of the things I just said might have been covered while I was typing.
