Iconic Hollywood stars of the seventeenth century were seen in these shaped glasses. But again, Rectangular eyeglasses are still competing in the fashion race. These fashionable glasses are ideal for people with a round face. These glasses add more sharpness to the round features, making your face look lengthier and skinny.
