iSight on Macbook Pro not on focus

Hi there, i'm experiencing an annoing issue with my built in iSight: is not on focus, with every application i try, Facetime, Photo Booth or whatever, the camera is not focused.

This is what System Information tells me:

Built-in iSight:

Product ID: 0x8507

Vendor ID: 0x05ac (Apple Inc.)

Version: 4.19

Serial Number: 8H92G01W040Y3L00

Speed: Up to 480 Mb/sec

Manufacturer: Apple Inc.

Location ID: 0x24400000 / 2

Current Available (mA): 500

Current Required (mA): 500

I've downloaded iGlasses but i didn't get the point on what this application could help me out.

Any suggestion from your side? Is the Camera gone?
