A circular face means that the length and width of your face are equal, with the chin rotating and the smoothness of the borders, and the best glasses are those that extend your face more length and highlight some of your features, so you should choose glasses with geometric square and rectangular shapes.

You can also rely on gazes whose upper bridge protrudes towards the outside, and you should avoid glasses that increase the roundness of the face, such as small glasses or round or oval shapes.

The face is square

A square face is characterized by the convergence of its length and width, with clear outlines and angles in addition to the width of the jaw and forehead.

Glasses that are oversize and have too much detail and width in the upper part are not suitable.

Square, rectangular, or narrow-framed glasses are not suitable.

The face is rectangular

In a rectangular face, the length is greater than the width in addition to the forehead area is characterized by being high, so you should buy sunglasses that reduce this difference and it is preferable to rely on oval or circular shaped glasses in addition to choosing them with a relatively large width. As for square or rectangular glasses, they are Inappropriate.

The face is oval

Both the length and width are commensurate with the soft features, and this is what makes buying sunglasses so easy. There are many suitable options such as large-sized, square, or rectangular glasses and cat eyes, while the small and narrow glasses are not suitable.
