Doesn't he pretty much figure it out in Year One and use not having his glasses as plausible deniability?
It's a possibility that his "I'm practically blind without my glasses" was a ruse but it's not like he then tells Batman he's got something stuck in his teeth. If it were a lie, I think the world's greatest detective would've caught on by now in which case, Batman would have no doubt that Gordon knows. Since Batman doesn't seem to be certain one way or the other (or seems to assume Gordon doesn't know) I don't think the Commissioner knew that early on. This does raise an interesting question: if Gordon knows, when did he learn the truth?

In Batman 431, he asks Batman if Robin's with him that night and doesn't seem to understand why Batman hesitates before telling him no. When he meets the third Robin in Batman 465 during Tim Drake's first night out, he approaches him as if he's speaking to the previous Robin.
I think elbobbo has the best answer - that it depends upon who's writing the story. Blind Justice (Tec 598-600) pretty blatantly had Gordon approach Bruce Wayne and tell him he knows, but NML as Joriss pointed out seems to contradict that.
I'm not so sure about that. He's looking Bruce right in the eyes when he says it. I'm not sure if it meant that he knew he was Batman but it certainly was meant to be taken more than literally or it wouldn't have been drawn that way.

Morrison: Oh yeah. There's a big scene with Gordon in the Bat Bunker coming up soon that addresses just how much Gordon knows or suspects.
I doubt we'll get a clear-cut answer--more likely a "Oh, heck, you're that Nightwing fellow, aren't you" --but we'll see. You can read the article here.
That scene in BoP came as a shock to me -- because in my Batman-related comics from the late 70s and early 1980s, it was repeatedly made clear that Commissioner Gordon knew his daughter was Batgirl, and she knew he knew, and so forth! For instance, when she got lured into an ambush and shot in the arm by an assassin working for General Scar, back around 1980, she didn't try to invent some cock-and-bull story for her daddy about how the shooting had happened -- she just told him the real story!

You didn't think you were really fooling me, did you?"
Ohm, Sweet, Ohm
Gordon wouldn't be much of a detective if he hadn't figured basically figured things out. He maintains deniability to protect Bruce, Barbara, himself, et al.
