Why do I have to wear my glasses now to take a picture with my camera?

I dropped my Canon Rebel. :) I don’t to talk about that, but when I started checking it over to see if it was hurt I quickly realized it wasn’t focusing. I started checking settings, and the switch was set to MF (‘Manual Focus,” although it could have doubled as the initials for another phrase I was so upset.) Don’t see how dropping it could have done that, as the button is recessed and tucked in next to the lens. But, anyway, I reset it to AF, and it is now focusing.

Here’s the weird part ya’ll’ll think I’m crazy: Before I had to take off my glasses to shoot because everything would be WAY over over sharpened, over-focused when I saw it thru the lens with my glasses on. Think of when you put on a another person’s glasses whose eyes were worse than yours. So I only took pictures without my glasses.
Now, however, if I don’t have my glasses on for the shot the camera says it’s focused, but thru the lens it’s as blurry to me as distant objects are when I look at them with out my glasses. So now I have to wear my glasses to see what the camera is seeing, and I don’t like that because my eye doesn’t fit against the eyepiece.

WTH???
