For men, the RB3183 model is one of the most popular Ray-Ban models because it radiates pure casualness and understatement. The semi rimless glasses are made of light metal and their aerodynamic shape is very reminiscent of speed. The rectangular shape of the glasses has been chosen to flatter any facial shape. The rubberized temple ends and the plastic nose pads guarantee a perfect fit and good wearing comfort. Since everything is kept in classic black, the glasses can be combined with any outfit and its simple design makes them suitable for both business lunches and after-hours beers. The pilot green shade completes the overall picture and protects the eyes 100% from UV rays.
