It is not possible to polish spectacle lenses to get rid of scratches without altering the power of lens, as a result it would be necessary to replace the lenses.  All our lenses come standard with scratch resistant coating and to help prolong the life of this coating and to enable you to keep your lenses pristine for a longer period, we do recommend to always clean them with a lens spray and clean cloth and to keep them safely in a case if not worn.
