Using your Sanctum sports sunglasses is easy. Just put them on before you start your activity. They're great for all sorts of active things like running, cycling, or working out at the gym. When you're done with your activity, don't just throw them around. Put them in their case to avoid scratches. To clean them, use a soft cloth and some mild soap and water. Avoid using harsh chemicals as they can damage the lenses and frames. Also, keep them away from extreme heat or cold, as this can affect their shape and performance. With proper care, your Sanctum sunglasses will serve you well for a long time.
