Knowing some of the basic shapes is not enough to understand the huge variety of current eyeglass styles. There are theoretically seven basic facial shapes which can generally cover all folks around the world, namely, round, oval, oblong, base-down triangle, base-up triangle, diamond and square. Some people may think that there should be corresponding shapes in eyeglass frames. This is partially true and square eyeglasses are one of the primary members.

Square differs most from round and oval. Thus square eyeglasses are most suitable for people who have a round or oval face. This rule is set to compromise the noticeable facial features. In an opposite case, round eyeglasses are mainly for wearers who have a square or oblong face. It is easy to work out other match-ups by following the same tip.
