Store these sunglasses in their case at a temperature between -10°C and +35°C. Avoid exposure to direct sunlight in closed spaces with high temperatures, such as in a car without air conditioning (e.g. car dashboard), as high temperatures may alter the features of the glasses.

Use a soft damp cloth and mild soap to clean the glasses, then dry them with a soft, clean cloth. Do not use solvents (e.g. alcohol, acetone) or aggressive detergents which may alter the features of the glasses.
