To get as many years of enjoyment out of your Lunor frames as possible, be sure to care for your glasses well and clean them regularly. From time to time, you can bring them to your optician to be checked or cleaned and, if necessary, for a new adjustment to ensure optimal wearing comfort. Do not try to repair your frames yourself, tighten screws, or the like. Your optician has the experience and necessary tools for this. Do not expose your frames to extreme temperatures or aggressive substances (e.g. cleaning agents, chlorine or salt water).
