Metal frames have been the traditional choice for many years and can suit several face shapes. They are made with a thin lightweight material and give you a look that’s tasteful yet subtle. Although they don’t come in as many colors and styles as plastic frames, they are available in a variety of colors for you to choose from. If you’re looking for a casual metal frame, choose a finish that’s brushed and flat. Want some more flair to your frame? Look at metal frames with shiny and polished finishes.
