Aviator (Sunglasses)

The teardrop is the tell. Each lens is wider at the top and tapers down and outward. The glass extends below the cheekbone line and blocks light coming up off water, snow or a road surface. Military pilots got the shape first, because a downward gaze at instruments needs cover exactly where most frames have none.

Metal construction defines everything else. A thin wire rim carries a second bar across the top above the nose. That double bridge is structural rather than decorative, since it stops a wide thin frame flexing out of shape. Silicone nose pads on adjustable arms let you raise or lower the lens on your face. Aviators sit correctly on bridges that a molded acetate frame simply ignores. Thin metal keeps the weight down, and bar temples that run straight back instead of hooking behind the ear take pressure off the sides of the head.

Wayfarers cover a similar eye area in thick plastic with a flat brow line, reading casual where an aviator reads classic. Round frames share the metal and nose pad build but drop the taper, so they protect much less below the eye. Sport frames wrap toward the temple to close the side gap an aviator leaves open, and shields go further still. Among metal frames, this is the one that suits square and heart-shaped faces best, since curves soften a strong jaw.

Driving, boating and skiing all suit the shape, and the low coverage matters most in all three. Narrow faces often struggle, because standard aviators run wide and the lens then sits past the cheek with a gap at the side. If you are rough on eyewear, think twice, since thin wire bends easily.

Bend the frame gently at the bridge in the store: quality metal springs back, and soft alloy stays where you put it. Nose pads should be replaceable, as they yellow and harden after a couple of years and cost very little to swap. Rinse salt spray off with fresh water before wiping, since dried salt crystals scratch a lens the instant a cloth drags them across it.
