Oval – Frames should not interfere with the oval face’s natural balance. Choose frames that are as wide, or wider, than the broadest past of the face.
Oblong – Choose frames that have more depth than width, have decorative or contrasting temples that add width to the face, or a low bridge to shorten the nose. This will make an oblong face appear shorter and more balanced.
Square – Choose narrow frames that have more width than depth to make a square face appear longer and to soften angles.
Round – Try more angular styles and frames that have more width than depth to lengthen the face.
Base up triangle – Choose frames which are wider at the bottom and light in colour. Light materials, and even rimless styles, will help minimize the perception of width at the top of the face.
