Following the advice of some knowledgeable people, I use filtered tap water and a cloth of 100% cotton - usually a plain white handkerchief - to clean my eyeglasses and prescription sunglasses.
I'm told that combination won't affect any coatings on the lenses, and will keep scratches to an absolute minimum.
Seems to have worked well over the years.
But today I was in an eyeglass shop, and they were selling all kinds of cleaning sprays and cloths.
So it got me to wondering - anyone use a product or combination that works better than plain water and a clean white cotton cloth?
