How to fix my front camera on my iPhone 5?

I cracked the screen pretty bad and went and got it fixed. Which is all fine and dandy, my iPhone is pretty again. But my front camera is blurry now. I guess because of the way the iPhone fixer people put the glass on it. But I just wanna know if there's a way I can fix it

There probably isn't anything you can do if you're not computer savvy enough to figure this out yourself. Take it back to where you got it repaired and see if they will fix it for you.
