Aviator glasses are remarkably versatile and can suit various face shapes, particularly those with square, heart, and oval contours. The classic teardrop design helps balance the angles of square faces, adds length to heart-shaped faces, and complements the symmetry of oval faces. However, with variations in frame size and lens shape, individuals with round faces can also find aviator styles that provide a flattering contrast to softer facial features. The key is to try different sizes and designs to find the perfect match for your face shape.
