No matter which style you choose, some basic care will be required to minimize lens scratches and keep the frame and nose pads clean. Wet lenses on both sides before wiping clean Always use a soft, 100% cotton cloth (not a shirt!) Launder the cleaning cloth regularly to remove debris. Always use an approved cleaner, or soap and water. Wash the entire frame in warm soapy water when dirty. Have plastic nose pads replaced often. Always store glasses in the case provided. Never leave glasses in a hot car or direct sunlight. Have your glasses adjusted every few months to ensure comfort.
