Clean using a damp cloth and a normal neutral detergent and dry with a soft clean cloth. Avoid the use of solvents such as alcohol and acetone and harsh chemical detergents that may damage the eyewear. When not in use, sunglasses should be kept in their case and stored at a temperature between -10°C and +35°C. Avoid exposure to sunlight in closed non-airconditioned environments (e.g. on a car dashboard) as the temperatures reached in these conditions may damage the eyewear and adversely affect its functioning. If the sun lenses suffer any wear and tear, becoming scratched or opaque, for example, we recommend replacing them with original spare parts.
