The Nelson model is the masculine design of this collection. For both men and women, this design is characterized by its elegance. With edges on the front it makes a difference. In this case we have introduced the color black, combining it with a gray lens, which suits it perfectly. The lens we have used is gray because it transmits light uniformly and better respects natural colors. It is a good choice for driving.
