Loro Piana eyewear is carefully manufactured using exclusive, long-lasting materials. We recommend replacing the lenses, if they have been subjected to a 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 lenses. Eyewear should be stored in its original case in a dry place away from heat and light sources. Fold one arm over the other, and wrap in the microfiber cloth provided.
