Sunglasses buying guide

When buying sunglasses online you’ll want to get the fit right first time, as well as the right style to flatter your face shape and a pair that suits your lifestyle. Here’s everything you need to know about buying fashion and sports sunglasses.

Styles and face shapes

Oval face

Oval face

Oval faces are evenly proportioned and softer in shape, so they suit most sunglass shapes. From cat’s eye to more angular styles, you can just be adventurous.

Rectangular face

Rectangular face

Defined by high cheekbones, and a longer face. Rectangular face shapes suit wider sunglass lens shapes or even wrap-around styles. Avoid angular square frames which could emphasise the length of the face.

Round face

Round face

If you have a rounder shaped face, to balance out your features it’s best to avoid oval or round lenses; instead go for more angular geometric sunglass shapes like rectangular or square frames.

Square face

Square face

A square face is normally wider, with a broad forehead and wide jawline. To balance out your features, choose oval frames that will soften your face, and definitely avoid angular geometric styles that will draw attention to your angles.

Styles of sunglasses

Aviator Sunglasses


Aviator sunglasses or ‘pilot's glasses’, were developed in 1936 by Ray-Ban for pilots to protect their eyes while flying, hence the name aviators.

Cat%27s Eye Sunglasses

Cat's Eye

Cat’s eye sunglasses feature a characteristic up-sweep to the top right hand side corner of the outer edges of the frame. Made popular in the 1950s
and 60s.

Wrap Sunglasses


Wrap styled sunglasses or visors generally have a more sporty feel as the lens curves around the face, making them great to shield you against brightness coming from all angles.

D-Frame Sunglasses


D-Framed sunglasses are so called because their shape looks like the letter ‘D’ turned onto its side. Mostly made from an acetate plastic frame.

Square & Rectangular Sunglasses

Rectangular and Square

Rectangular and square frames can come in metal or acetate frames, and are great for flattering rounder face shapes.

Lens types and sports sunglasses


Sun light waves can travel in all directions and bounce off surfaces like water, glass or mirrors, with some concentrated horizontally. So, polarised lens were designed to reduce 90 -100% of the glare reflections to make viewing through sunglass lenses more comfortable. That’s why polarised lenses are slightly more expensive than standard.
