Using these sunglasses is a breeze. Just put them on like you would with any regular pair of sunglasses. When driving, they'll reduce glare from the road and oncoming cars, giving you a clearer view. For sports, they'll keep your eyes protected from the sun. Here are some things to keep in mind. Don't scratch the lenses. If they get dirty, use a soft, clean cloth to wipe them. Avoid leaving them in hot places like a car dashboard, as this might damage the frame. To maintain them well, store them in the provided case when not in use. This will protect them from getting bent or scratched. With proper care, these sunglasses will serve you for a long time.
