Some suitable eyeglass frames for round faces include angular frames, rectangular frames and upswept frames. Angular or rectangular frames add sharp angles to a curvy face and elongate the face, while frames that sweep upward at the temples draw attention to the cheeks and eyes.
Frames that are unflattering on round faces include small or short frames and round frames. Round faces often look small because they don't taper at the top or bottom the way other face shapes do, and small frames enhance this unwanted effect. Round frames make the face look even rounder and fail to balance the natural curves of the face.
