I too wear glasses. It depends on the kind of mask.

Disposable surgical masks with the "metal-bendy-bit" for the bridge of your nose has worked great for me.

I also use cloth masks all the time due to the ease of keeping one on me, and washing it with the whites and bleach at the end of the date. Cloth masks definitely fog up my glasses more, but I find that adjusting them and not breathing through my mask help me.
