Constructed from a combination of metal and either plastic or aluminium, the lenses of the glasses are fixed in metal frames which then insert into the plastic‘brows’, which are attached to the temples of the glasses.

Round sunglasses are originally coined as teashades. These glasses are made up of medium-sized, perfectly round lenses fitted in a slim wire frame and combined with silicone nose pads.

Square glasses are easily identifiable due to their angular corners and are best suited for round, rectangular, oval and some diamond face shapes.
