If your face has an equal or nearly height to width then you likely have a round face. A rounded face won’t have pronounced cheekbones, so choose a pair of sunglasses that are wider than your face to give it some definition. With round faces always choose the opposite of round when choosing glasses. Contrast by choosing a square or rectangular shaped glasses. Get frames with nose pads, they tend to look great with big cheeks or if you have a flat nose.
