Flip Up Round Sunglasses ZN4010

The Flip Up Round Sunglasses ZN4010 (ZN4010) is built for everyday wear. Part steam punk, part aviator heritage: the double-bridge round frame carries a hinged second lens that flips up when the sun hides and snaps back down the moment it returns. It is a conversation piece that still does its day job properly — full UV400 under both lenses. Weighing just about 30 grams, it sits light on the nose and stays put through long sessions, commutes and weekends outdoors.

Highlights

• Flip-up lens layer — hinged front lens flips smoothly and locks in place
• Double-bridge frame — vintage aviator-inspired metalwork with reinforced rivets
• UV400 protection — both lens layers block 100% of UVA and UVB rays
• Three finishes — Brown Gold for warm retro fits, Black and Grey for daily carry
• 30-day returns — try them at home; if the fit is not right, send them back, no questions asked

Care & maintenance

To keep your flip up round sunglasses in top condition, rinse them with lukewarm water when dusty, pat them dry with the included microfiber cloth, and store them in the pouch whenever they are not on your face. Avoid leaving them on the car dashboard in summer — prolonged heat can stress lens coatings and warp frames over time.
