Using these Pit Viper sunglasses is easy. Just put them on your face like regular sunglasses. The adjustable design allows you to fit them comfortably. When you're not using them, don't just throw them around. You can use the included Limpcloth™ to clean the lenses gently. Avoid scratching the lenses on rough surfaces. Also, keep them in a safe place to prevent them from being sat on or stepped on. If you want to change the look or fit, you can attach the Reach - around™ Earpieces. Just make sure they're securely attached. And remember, these sunglasses are tough, but still treat them with care to keep them in good shape for a long time.
