The rectangular-shaped sunnies have a fresh and polished feel. The lenses are made of polycarbonate, which makes them durable and far more impact-resistant than normal glasses. The grey transparent color of the frames has a refined form, which then makes a switch to the color black across the temple. You can wear them to work or outdoors as the style is a little simple and goes well with any event, formal or informal. Pair them with grey formal pants and a clean white shirt, which will help exude an aura of professionalism and sophistication.
