Choosing new sunglasses for everyday wear isn’t exactly rocket science, but there are a few things to consider before investing in your next pair. First, decide on the functional elements you need — like polarized lenses or coatings that combat reflections, water and oil — then pick out a frame shape that complements your face. The goal is to accentuate your best features, and in general, the best way to do that is to wear frames that contrast your face shape slightly.

Not sure what your face shape is? Look at yourself in the mirror and decide if your face is round, square, oblong, heart, diamond or triangular (it may also be helpful to use a picture to help you better visualize the shape). Then take a look at our recommendations below — there are plenty of stylish options to highlight your best qualities.

Round

Stay away from circles, unless you want to over accentuate the round shape of your face. Aim high with aviators or stick to square, angular frames.

Oval

It’s hard to go wrong an oval face — most sunglasses will look great on you. Just make sure the frames aren’t wider than your face.

Square

Rounded corners are key to success if you’ve got a square jaw. Look for frames sized to match you in width, but with soft lines. Too many hard angles won’t do you any favors.

Oblong

Similar to our square-faced friends, you want to go with softer lines and rounded corners. Wayfarer styles work well, but avoid small frames.

Heart Shaped

Square frames complement a narrower chin, adding different angles that add a layer visual of visual interest. Avoid anything oversized or teardrop shaped, and reach instead for something with a sharper corner.

Diamond

Most frame shapes will work well for diamond faces, so long as they’re in keeping with your proportions. Anything wider than your cheekbones will make the widest point of your face appear even wider (and, in turn, make your chin and forehead appear smaller than they actually are).

Triangular

Frames with more going on up top are your friend. Anything teardrop shaped will emphasize dimensional balance. Square frames with deep lenses are simple and effective.
