To use these mauve round sunglasses, just put them on your face like you would with any regular pair of sunglasses. They're great for protecting your eyes from the sun while adding a trendy touch to your outfit. When you're not using them, keep them in a protective case to avoid scratches. Clean the lenses with a soft, dry cloth. Don't use harsh chemicals or abrasive materials as they can damage the lenses and the frame. Also, be careful not to bend the arms of the sunglasses too much, as this can cause them to break.
