Sunglasses Styles: Choosing Round, Square or Aviator Frames

A sunglasses shape can change the character of an outfit, but it still has to sit comfortably. Use style to build a shortlist, then check the dimensions and sun-lens specification before buying.

Round frames for a softer outline

Round shapes can give a simple outfit a more noticeable vintage influence. Compare lens size and bridge shape: a compact round pair and a large round pair will not create the same look or fit. Do not choose only from a face-shape rule.

Square and rectangular frames for a defined line

These shapes create a straighter outline. Pay attention to total width and the upper rim; a frame that extends beyond where you want it to sit can look and feel quite different from the product photo. Use your old pair as a reference with the frame-size guide.

Aviator shapes for a distinctive profile

Look at lens depth, bridge construction and how the frame sits on your nose. A familiar aviator silhouette can come in substantially different sizes. Nose-pad and bridge designs deserve a closer look when slipping has been a problem.

Finish the decision with the lenses

For prescription use, confirm which styles accept your required lens combination. Choose tint and polarization according to the activity and check the UV specification separately.

Choose a shape you expect to enjoy wearing regularly. A style that suits your fit and daily routine is a more useful purchase than a prediction about what everyone else will wear next.
