To use these Tifosi Centus sunglasses, simply slide them on your face. The Tifosi Glide technology makes this process easy and comfortable. Wear them when you're out on the driving range or on the golf course to protect your eyes from glare and UV rays. When not in use, store them in a protective case to prevent scratches. Clean the lenses with a soft, dry cloth regularly. Avoid using harsh chemicals on the frame or lenses. If the nose pieces start to lose their grip, you can gently clean them to restore their functionality.
