We recommend that you keep a soft lens cloth to allow you to clean your glasses as and when necessary. Be aware that other materials may damage and scratch the lens. There are also special cleaning sprays that you can use to help remove stubborn marks.
Every pair of glasses we sell comes with a cleaning cloth and protective case.
Penzer Opticians sells cloths and cleaning sprays.
It is recommended that you always use two hands to put on and take off your glasses to prevent damage to the arms. We also suggest that you do not wear your glasses on your head when not in use.
