Protect your sunglasses from scratches

Glass lenses are more resistant to scratching than polycarbonate lenses, but whether your lenses are plastic or glass, it’s important to store your sunglasses in a case. Don’t just drop sunglasses in a purse, laptop or messenger bag, or shove them in your pocket. Your sunglasses are likely to get scratched by keys, pens or rough denim fabric.

A hard case is ideal, says airline pilot Steve Arbetman, who owns Flight Sunglasses. “If you don’t like carrying a hard case, at least put them in a microfiber pouch,” Arbetman says. “That will still protect your glasses and can double as a cleaning cloth.”
