National Sunglasses Day–Today’s the day to celebrate some of the most stylish (and necessary) accessories on the market: men’s sunglasses. Not only are sunglasses essential for protecting your eyes from harmful UV rays and perpetual squint, but they’re also essential for looking cool. Sunglasses haven’t been a major fashion accessory forever, though; it was in the 1940s that sunglasses became en vogue to wear regularly, especially at the beach. Here, we highlight two of our favorite styles at the moment, the Illesteva Half/Half Hooked sunglasses and Oliver Peoples West Cabrillo shades. Wear them outdoors, at the beach, or at night–today’s the day to celebrate stylish eyewear.
