In cloudy, overcast, or stormy conditions, we reached for Costas with the new Sunrise Silver Lens. The pale, golden lens has 30 percent visible light transmission—enough to protect our peepers while still providing contrast in low-light conditions. The Sunrise Silver was developed with fishing in mind, but it works great in winter: Just as the polarization blocks surface sheen on water, it dimmed snow glare and helped us pinpoint skiable lines down open aprons in the San Juan Range. Caveat: You’ll fry your eyeballs if you wear these on bluebird days; pack high-light spares.
