I've given up on working on the glasses end of things. Now I try to find head/face gear that lets my breath through without fogging. Several years ago I found a nice knit type facemask, not too tightly woven(?),that allows my breath to go through and won't fog me up. I can even pull it up over my nose and generally not have a problem. Warm hat on the head and that over my face/neck and I'm toasty in our Midwestern weather! Sorry that I can't tell you a brand, don't even remember where I bought it. Just thought you might want to work from a different direction to tackle the problem.

I don't care about wearing glasses, no big deal since I've been wearing them since I was little kid. This ONE ISSUE is going to put me over the edge for surgery!
