Loro Piana eyewear is carefully manufactured using exclusive, hard wearing materials. We recommend replacing the lenses, if subject to significant impact. Clean under running water with neutral detergent and dry with a clean cloth, holding the frame and gently wiping the lens. Avoid using solvents, methylated spirit, or dirty or abrasive cloths, as these can damage the filters. Eyewear should be stored in its original case in a dry place away from heat and light sources. Fold one arm first, over the other one, and wrap in the microfibre cloth provided.
