After 20+ years of riding with contact lenses, I'm going back to glasses for riding (darned astigmatism). With contacts, I chose goggles that had enough air flow not to fog, but yet not dry out the lenses (I used Smith with double pane lense and roll-offs). With glasses I'm finding that my glasses tend to fog up in slow going (my only goggles that fit over my specs are Scott 87 OTG). I've not got the double lense yet for the Scott. Are there any brands or models that fit over glasses well and flow air? I have an old pair of Smith violators with the removable foam that I will experment with, but can't find a double pane lense.
