The second one is each time you clean them, check the screws and hold the frame together since it’s much easier for you to tighten a screw that it is to search for it after it falls out. After you finish the cleaning, do not rest your glasses on the lenses. This will scratch, and you know well it’s hard to see through scuffed or scratched lenses. Good eyeglasses can last several years, especially with proper cleaning and care.
