I have to wear eyeglasses when I ski and unfortunately they fog up almost immediately with my new helmet (lack of ventilation compared to my old helmet). My old helmet didn't have the same issue.
I need some recommendations for a good anti-fog spray that I can buy in a Walmart or something for eyeglasses.
A ski shop sold me this and it is absolutely useless, as in it fogs seconds after application:
