Von Zipper says it sold 400,000 pairs of glasses on a global level in 2015. About a quarter of the volume is now represented by its optical line of prescription frames, which was re-launched 4-5 years ago. Von Zipper expects a slight sales increase by the end of this year. Its most important markets are the U.S., Australia and Europe, with France being one of the biggest markets. Sales in the sporting goods sector account for 80 percent of total sales, but Von Zipper signed contracts with dedicated agents for the optical retail sector in France, Germany, the U.K. and the U.S. that became effective this summer, After launching a new polarized lens that balances out the color spectrum, Von Zipper next year will launch lenses with multiple tints, produced by Essilor, for specific purposes such as water sports, action sports and lifestyle.
