Ah, yes, bridge shape. The bridge distributes the weight of the glasses evenly across the nose, ensuring comfort and stability for those with narrow noggins. Either the saddle bridge or the keyhole bridge works well for folks with slender faces. The truth is that there really is no “best bridge” for face shapes. When considering bridge shapes think about it like this – if you crave the stability, comfort and support of a nose-hugging cowboy companion, pick the saddle bridge. Or if you think you’d enjoy adding a wee bit of character to your eyewear, the quirky keyhole shape is the right bridge for you.
