It is that time of year again. Whether hiking, hunting or a match I seemed to be cursed with glasses that easily fog. It doesn't matter whether they are goggles or small/large framed eyeglasses it seems to start whenever there is any kind of exertion of 15 minutes or more on my part. I have used many products including Cat Crap, Fogtechdx, Dawn, spit and so on but although some products will delay onset of fogging, it doesn't stop or eliminate long term (say an hour or more). On a bicycle, fog dissipates once there is movement but when I stop at a light, it will start right back up.
Any suggestions or thoughts on how to combat this debilitating and chronic problem.
