1. Oval Face: You're in luck! Almost all shapes suit you, especially rectangular or aviator glasses.

2. Round face: Choose glasses with sharp angles or rectangular glasses that add definition and make the face look longer and narrower.

3. Square face: Opt for round or oval glasses that soften the sharp lines and angles of the face.

4. Heart-shaped face: Aviator or cat-eye glasses are ideal, as they balance a wide forehead and a narrow chin.

5. Elongated face: Oversize glasses or glasses with tall lenses help to create the illusion of a shorter and more proportional face.

In addition to style, always consider comfort and UV protection to find the perfect sunglasses for you.
