Square Face Oval or round frames balance the lines and soften strong features. Round Face Add contrast and unique lines to your round face with rectangle, geometric, cat's eye, or butterfly frames. Heart-Shaped Face If your face is heart-shaped, you might find that aviator, rectangle, oval, or round frames go well with your features. Triangular Face Eyeglasses with a browline, cat-eye, or aviator shape can flatter a square face while drawing the eye upwards. Oval Face Framing an oval face with a square or rectangle makes the delicate curves even more pronounced.
