Rain-X works very well, and I drive everyday with a toned down set of Ray Bans with a gold mirror finish, has a mild yellow tint....the mirror helps on the real bright sunny days....the rest of the time I can wear them until dark....then you need a brighter yellow tint....I have logged over 3 million miles in the big rigs now, and only god knows how many in a car, driving or patroling....I always clean the the side windows and the windshield every morning....rain or shine....it will help with the glare...rain x works so well, I rarely use the wipers, only on intermitant low setting .....
