Eye, help(?)

So all of a sudden, around an hour ago, my eye started hurting. Not my eyelid, my eye. It's not burning or stinging either. It's really weird. My vision is a tiny bit blury in that eye, and it's a little beat teary, but other than that, it feels like it's just strained. Anyone have any clue as to what this could be? So far I have just been resting that eye in the dark.
