The most expensive glasses will look cheap if you violate this rule

Most men choose glasses the same way they choose a logo: by brand. The problem is that even the finest eyewear will look wrong if the geometry fights your face. The key is contrast. Round faces need angles. Square faces need curves. Oblong faces need horizontal weight. Diamond faces benefit from stronger brow lines. Then come the universal rules of fit: proper frame width, centered eyes, and enough clearance from the cheeks. The Wayfarer, Aviator, Panto, and Clubmaster have endured for decades because good proportions never go out of style. In eyewear, geometry matters far more than price.
