Best Sunglasses

The Persol 649’s character comes from proportion and construction rather than an oversized logo. Originally designed for Turin tram drivers, the keyhole bridge, gently sloping brow, and rounded lenses suit a remarkable range of faces. It is recognizable without becoming costume, and substantial enough to provide presence while retaining the ease expected of an everyday summer object.

The acetate frame is cut and finished in Italy, with Persol’s arrow hinge providing a small graphic signature that also reinforces the temple. The Meflecto system places flexible metal cylinders in the arms, allowing them to adapt around the head rather than pressing at one point. Glass lenses offer excellent optical clarity, and the frame’s thickness gives the hinges and lens rims useful material to work with.

Glass is heavier than polycarbonate and can break if abused. The 649 also comes in several sizes, making a proper fitting essential; a frame too wide loses its authority, while one too narrow defeats the flexible temples. Rinse salt and grit before wiping, use the case rather than a shirt collar, and have loosened screws adjusted. Well fitted, the weight settles comfortably across bridge and ears.

Sunglasses are easily reduced to seasonal identity props. The 649 has lasted because its practical origins produced a form stronger than fashion. It works with a T-shirt, raincoat, or tailored jacket and improves as polished acetate gains minor signs of use. Choose a classic tortoise or black frame with lenses suited to real light conditions, then keep it long enough to become yours.
