Features and Benefits:
Opsales "patented, all metal" flip up mechanism securely clips to the top of your plastic or metal frame, allowing you to obtain polarized, 100% UV protection with Opsales superior polarizing lens system, protecting your eyes from the sun's damaging rays and blinding glare. In addition, Opsales polarized lenses are also highly scratch resistant. You now have the convenience of just flipping them up or down while boating, fishing, or just driving your car. Opsales patented flip up "all metal" mechanisms are virtually unbreakable, and the metal mechanism from our proprietary "sticky" vinyl clip coating system protects your lenses by preventing slippage and scratching.
All Opsales sun lenses filter 100% of ultraviolet light up to 400nm, and meet or exceed all local and international standards pertaining to optical clarity, durability, and safety, including but not limited to ANSI Z80.3:2008, EN1836:2005, and AS/NZS 1067:2003.
