I sometimes wear my glasses. I use the scott treatment. I also use ski goggles from scott. the treatment works good, and i put it on the inside of the goggles lense, and on both sides of my glasses. if i cant find it, I use the clearest of diswashing soap at a 1-5 mix with water. (one part of soap to 5 parts water). put a drop or two on each lense and rub until clear and dry. if you soak a cloth in the solution and carry it in a baggie you can treat the lenses again on the trail, or carry the scott cloth and or the scott solution. lots of other commercials out there.
