If you’re a sunglasses purist, you’re probably already on the hunt for Vintage Persols like these 69262 aviators from the Eighties, top ($750, silverliningopticians.com). Style fiends seek out these 1960s to 1990s models for their unique, never-reissued design, hefty, hand-built-in-Italy quality, and mineral-glass lenses. The lenses aren’t polarized, though, so if you need modern sport glasses that perform, go with the Kaenon Burny, middle ($229, kaenon.com). They’re designed to be worn in the harshest of conditions, but they don’t suffer from the overaggressive wraparound style that’s been a plague on sport sunglasses. If you want to go classic, pick up the Randolph Engineering Crew Chief ($139, randolphusastore.com), traditional alloy-framed aviators that are lightweight but built to U.S. military and NASA specs, and have been around since Reagan was in office.
