Extend your frame life
Always clean your sunglasses by using a cleaner specifically developed for eyewear lenses, with a microfiber lens cleaning cloth or sunglass bag.
To avoid damage to the lens, DO NOT clean your glasses with t-shirts, paper towels or kittens. These can grind dust and fibers into lenses leaving scratches.
Avoid using household detergents, soaps or glass cleaners, which are highly corrosive and can damage your lenses quickly.
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.
DO NOT place your sunglasses on the dashboard or your car. The extreme heat can distort the shape of your sunglasses.
When not wearing your glasses, never rest them face down on their lenses. Always keep them in their protective microfiber case or hard case.
These will ensure that they will be in good shape the next time you reach for them.
