Viva introduces there new Mark Nason Collection of eyewear. They are indeed a step above what has been seen lately. I love the unique design of the brand which sets it apart from other eyewear designers. I am loving the retro but modern look of the eyewear. The collection features zyl and metal frames for men and women. The frames are also designed with some elements of leather to help stand out from other designs. This collection is a great addition for Viva.
