I spray painted my car and noticed over-spray on my polycarbonate eyeglass lenses the next morning. I tried soap and water but that removed none of the paint specks. I called my optometrist and they warned against using any solvent like paint remover or acetone on polycarbonate lenses. It would be OK on glass lenses, but i think polycarbonate is a plastic. So I tried 70% rubbing alcohol and some lens paper and with a little rubbing the paint specks came off. I quickly rinsed the lenses with water to remove the alcohol residue. The optometrist's office said it is not a good idea to let any substance besides water soak into the lenses as it may make them more brittle.
