With the many frame styles out there, finding the right pair can be complicated. Be sure to know your face shape to have a general idea of what you're looking for. You can tell what your face shape is by the area around your eyes to your cheekbones. Every frame works for oval faces, while rounded frames are better suited for square faces. It's all about contrasting the natural curves of the face with the angles of the frames. Heart-shaped faces should try bottom-heavy frames that don't accent the top of your face, while triangle-shaped faces should do the opposite and consider half-rimmed glasses with heavy detailing at the top. Consider these things when shopping for both eyeglasses and sunglasses.
