Cat-Eye vs Round vs Square Sunglasses: Which Shape Suits You?

Quick answer: Cat-eye frames suit almost everyone and are the most flattering choice for round and square faces, because their upswept line adds lift and definition. Round frames soften strong, angular faces. Square frames suit softer, rounder faces that want more structure. The simplest rule: choose a frame shape that contrasts your face shape.

Cat-eye sunglasses

The upswept outer corners lift the cheekbones and elongate the face. Cat-eyes are the most versatile of the three — genuinely flattering on round, square and heart-shaped faces, and an easy stylish option for oval faces too. If you're unsure where to start, start here. More on cat-eye sunglasses.

Round sunglasses

Soft, curved frames bring balance to strong, angular features. They're the natural counterpoint to a square face, softening a defined jaw. On a round face, though, round frames tend to echo the face and soften it further — so they're best avoided there.

Square and angular sunglasses

Geometric, squared frames add structure and definition. They flatter softer, rounder faces that benefit from sharper lines — the opposite of what suits a square face. If your features are already angular, look for softened corners rather than hard edges.

Which shape should I choose?

Match by contrast: angular frames for soft faces, soft frames for angular faces, and cat-eye when you want lift on almost any face. For a round face, see our round-face guide; for a strong jaw, the square-face guide; and for everything in between, the full face-shape guide.

Whatever you choose, check the lens

Frame shape is about flattery; the lens is about protection. Always choose UV400 — 100% UVA and UVB protection, essential under the UAE sun. Every ARVUE pair is UV400 as standard.
