Smith Barra Sunglasses Eyes on the Prize Chroma Pop lens technology sharpens contrast and pulls out natural color in ways standard lenses simply don't, so whether you're reading the water surface, scanning trail ahead, or navigating traffic, the picture is cleaner and faster to process. The 6-base curve gives the frame a modest wraparound fit - enough coverage to manage glare from the sides without boxing you in. The built-in side shields take that further, cutting backside glare that polarization alone doesn't address. The Evolve bio-based frame keeps weight down and sits comfortably on longer outings. Auto Lock hinges let you pull the Barra on or off one-handed without fumbling, which matters more than it sounds when you're mid-ride or mid-cast. Features Chroma Pop Lenses enhance contrast and natural color so your visual processing speeds up and you pick out detail faster in changing light Built-in Side Shields pair with the 6-base curve to block backside glare and lateral light that would otherwise wash out your view around water or open roads Evolve Bio-Based Frame uses 53% bio-based material in an injected polymer construction that keeps the frame lightweight without sacrificing durability Megol Nose and Temple Pads grip your skin with a nonslip hold that actually gets more secure when moisture from sweat or spray enters the equation Auto Lock Hinges hold the temples open so one-handed on and off is quick and reliable, whether you're gearing up or packing down Anti-Reflective and Smudge-Resistant Coatings reduce eye strain from sidelight reflections and keep the lens clear and easy to clean through a full day of use | Smith | Barra Sunglasses Men's In Matte Ash Marble/chromapop Glass Polarized Opal Mirror
