Your Face Is Round If:

The length from your hairline to your chin divided by three is longer than the length from the tip of your nose to the bottom of your chin.

Shades with a distinct flat top and squared edges trick the eye into seeing more angular facial features, offsetting the fullness of a round face. Plus, large frames that rest mid-cheek “elongate” the face for a slimmer appearance.

Your Face Is Long If:

The length from your hairline to your chin divided by three is shorter than the length from the tip of your nose to the bottom of your chin.

The upturned corners of classic cat-eye sunglasses pull focus up and out, adding optical width to beautifully balance a narrow face. Even better? The frames’ upward swoop gives features a youthful “lift,” while the oversize style helps conceal and detract from forehead furrows and camouflage crow’s-feet.

Your Face Is a Heart If:

The width of your forehead from temple to temple is longer than the width of your jaw from ear to ear.

$25.99, Amazon

The slightly rounded curves of wayfarer sunnies create a focal point that directs attention away from a pointier chin. What’s more, the contrast of a large pair with darker lenses and lighter frames cause glasses to “pop” off of the face, visually minimizing a wider forehead.

Your Face is Square If:

The width of your forehead from temple to temple is equal to the width of your jaw from ear to ear.

$16.99, Amazon

Spherical lenses with barely there aviator-style frames help soften a sharp jawline — all without adding any visual bulk to the stronger face shape.
