This Web Cam is manually focused. Turn the ring on the front to adjust the fuzziness out.
Use the camera software to see the focus while you turn the ring.

The circle/ring that the lens is enclosed in, can actually turn. Try turning it anti-clockwise (to the left). At first I thought it wouldn't turn as it was really tight turning it to my right, but I learned fast. Good luck.

Did you make sure the lens was clean? Wipe lens off the reset the webcam to its default settings. Slowly adjust the focus ring for best effect then adjust the video settings.

That particular model has Easy Focus; ensures crystal clear videos - just turn focus ring to adjust range from 10 cm infinite. I do believe if you turn it to the left it will zoom in, and to the right is zoom out. Could be the reverse of that tho. The focus ring is around the lense.

There are basically 2 adjustment can be made to focus your webcam, 1st is by the webcam software, try to search from the software any feature that can focus your webcam. The 2nd is the mechanical adjustment on the webcam itself, try to rotate the focus ring (webcam's eye) and see how the picture improvement.
