Leaking seal between your face and the mask
Your breath should exhaust through the respirator. If your fogging your glasses, most likely, the mask is not making a good seal. Besides fogging your glasses, if the mask is not making a good seal to your face, your also breathing in the stuff your trying to filter out

The exhaust of my breath is what is fogging the lenses, then I have a hard time seeing what I am doing.
