To use these sunglasses, simply put them on like you would any regular pair. Make sure the temples rest comfortably over your ears and the nose pads sit well on your nose. When you're out in the sun, these sunglasses will protect your eyes from harmful UV rays. Avoid scratching the lenses. If they get dirty, you can gently clean them with a soft microfiber cloth. Don't use abrasive materials. Store them in a protective case when not in use to prevent damage. Also, keep them away from extreme heat and direct sunlight when stored to maintain the quality of the frame and lenses.
