Using your Tifosi Selca sunglasses is a breeze. Just put them on like you would with any regular sunglasses, and the hydrophilic nose pads will adjust to your face for a snug fit. When you're out and about, the UV - protected polycarbonate lenses will shield your eyes from the sun's harmful rays. Remember to keep your sunglasses away from sharp objects to avoid scratching the lenses. For cleaning, use a soft microfiber cloth and some mild lens cleaner. Don't use harsh chemicals as they might damage the frame or the lenses. If you're not using them, store them in a protective case to prevent any accidental damage.
