Thanks

I don't have coated glasses but I have always cleaned mine by holding
under tap water to remove grit, moistening my fingers with soap (either
hand soap or dish soap), rubbing on lenses, rinsing off and drying with
tissue.

Using solvents on plastic lenses is looking for trouble and even with
glass lenses, coatings are plastic based.
