A microfiber cloth is usually all you need to clean smudges or dirt from the lenses and frames.
If you prefer to use a cleaning solution, we recommend a dedicated lens cleaning spray to protect the lens coatings. Do not use hot water, regular soap, dishwashing liquid, or any chemical-based cleaners, as they may damage the lenses.
Avoid leaving your glasses in direct sunlight or in hot, enclosed spaces (such as a car dashboard), as high temperatures can affect the glasses.
If the lenses come into contact with salt water, pool water, cosmetics, hairspray, sunscreen, or insect repellent, gently clean them immediately with a soft damp cloth.
Please note that heat and certain chemicals (including alcohol-based cleaners and hairspray) can damage the anti-scratch coating. We recommend removing your glasses before applying hairspray and waiting until it is completely dry before putting them back on.
