The metal frame is very light and comfortable to wear. It is both robust and classy. Brown is currently a trend colour and also an absolute timeless classic. The colour provides a nice contrast ratio between the skin and the colour of the eyeglass frame. Thus, the transition from eyeglasses to the face is harmonious and unobtrusive. Similar to grey, brown lenses don't distort the visual impression as much as other colours do. With all other shades, the eyes take longer to neutralize the colour impression. This brand of sunglasses, of course, also provides your eyes with optimum UV400 protection.
