No ‘anti-fog’ solution found in 23 years of cycling. i have to wear glasses to keep my eyeballs from freezing. i bought a pair of oakley jawbones a few years ago because they are vented…i wore them on a muggy summer morning and returned them the next day. i’ve found the brim of a simple cycling cap under the helmet does wonders to keep water off your eyes…but most effective with head down which calls for constant up/down head bobbing to look ahead.
When you ride bike or cycle in the rain or in a snow fall you have to need glasses. But glasses are freeze so, you need anti fog solution (c-clearantifog.com) which keeps the glasses clear and fog free.
