These semi-rimless smoke- or revo-lens plastic Khan men's bulk sunglasses are split into one of two categories. The first category is broken down into three sets of shades constructed with neutral colors. The other category is far more colorful and delightful. With the addition of the black sunglasses, more people can wear them. People who play it safe might not go for the more daring varieties in this product line. It's possible that people who are going to a tropical setting will likely have the more colorful varieties of these shades in their repertoire. If anything, these sunglasses are an adventure.
