I have had one pair of prescription Maui Jim's for a dozen years. Proper cleaning is the key to keeping scratches off the lens surface. A mixture of rubbing alcohol and water 80/20 with a cotton cloth wiper works best. NEVER a household window cleaner. I cringe when I see people wipe lenses on anything available.
