Smith certainly styled the Barra Chromapop Polarized Sunglasses for the streets, there's no doubt about that, but subtle undertones really optimize these lenses for fishing. The Chromapop lenses filter two specific, unwanted wavelengths of light that cause eye fatigue and color confusion in order to deliver greater definition and popping colors. The skies will look bluer, the grass greener, and the lake will be all the more beautiful when you pull a rainbow trout out of the water. Smith treated the backside of each lens to reduce glare when you're fishing away from the sunlight.Proposition 65 Warning for California Consumers: This product contains chemicals known to the State of California to cause cancer and/or birth defects or other reproductive harm.
