A round face has curvilinear lines with the width and length in the same proportions and no angles. To make the face appear thinner choose a bridge that widens the eyes and frames that are wider than they are deep, such as a rectangular shape.
The oval face is considered to be the ideal shape because of its balanced proportions. To keep the oval's natural balance, look for eyeglass frames that are as wide as (or wider than) the broadest part of the face, or walnut-shaped frames that are not too deep or too narrow.
The oblong face is longer than it is wide and has a long straight cheek line and sometimes a longish nose. To make the face appear shorter and more balanced, try frames that have a top-to-bottom depth, decorative or contrasting temples that add width to the face or a low bridge to shorten the nose.
- Triangular Base-Down
The triangular face has a narrow forehead that widens at the cheek and chin areas. To add width and emphasise the narrow upper third of the face, try frames that are heavily accented with colour and detailing on the top half or cat-eye shapes.
- Triangular Base-Up
This face has a very wide top third and small bottom third. To minimise the width of the top of the face, try frames that are wider at the bottom, very light colours and materials, and rimless frame styles (which have a light, airy effect because the lenses are simply held in place to the temples by a few screws).
Diamond-shaped faces are narrow at the eye line and jaw line, and cheekbones are often high and dramatic. This is the rarest face shape. To highlight the eyes and bring out the cheekbones, try frames that have detailing or distinctive brow lines, or try rimless frames or oval and cat-eye shapes.
A square face has a strong jaw line and a broad forehead, plus the width and length are in the same proportions. To make the square face look longer and soften the angles, try narrow frame styles, frames that have more width than depth and narrow ovals.
