I have tired of the constant difficulties I have with Contacts on multi-day excursions and have an appointment scheduled to get a new pair of glasses. I have this dream of glasses that I can hunt/fish/participate in athletics with that have photochromatic lense, bifocals, lightweight, resist fogging somewhat and will not hamper my shotgunning,rifle or archery shooting. Anyone have any suggestions, cost doesn't matter if it is takes away the difficulties of contacts in the field.
