Always wipe your sunglasses using a cleaner specifically developed for eyewear lenses and a microfiber cloth.
Keep your eyewear in their protective microfiber case or hard case when you're not using them. This will ensure they remain in good shape over time.
To avoid damage to lenses, DO NOT clean your glasses with t-shirts, towels or any abrasive material. These can grind dust and fibers into lenses leaving scratches.
Avoid using household detergents, soaps or glass cleaners, which are highly corrosive and can quickly damage your eyewear.
Sunscreens and other lotions can also damage the paint and coating on the frame.
Avoid submerging frames under water since certain frames and coatings will corrode over time.
When not wearing your glasses, never rest them face down on their lenses. Store them in an approved eyewear case or carrying pouch.
DO NOT leave your sunglasses on the dashboard of your car or in any place with extreme heat. This can distort the shape of your eyewear.
