These Khan-brand metal-plastic men's shield aviator sunglasses are different from the average pair of shades. Instead of having two lenses that are separated by a thin metal bridge, these shades have a single lens with no bridge at all. A lot of aviators are made of solid metal material, but these shades feature earpieces made of plastic. All the design elements on these shades create a different look from what you might expect. You will want to go into the world of aviators with an open mind. It's challenging to find matches for older aviators. That's not the case when you think of these shades.
