Round sunglasses were often referred to as "teashades" and "John Lennon sunglasses" during the 1960s. These terms are rarely heard today but remain a vital part of sunglasses' history.
Round sunglasses are one of the first frame styles to appear, mimicking the eye's natural shape. Round sunglasses as we know them today became popular in the 1920s.
Round sunglasses emphasize the soft features of rounder face shapes. Unless this is the particular look you're going for, we recommend square or rectangle shaped glasses to give round faces a flattering contrast.
