The five major optical retailers in Switzerland have formed AOVS, the first Swiss optical retailers' association. They are Fielmann, Visilab, Kochoptik, Berdoz Optic and McOptik. Together, last year they sold about 60 percent of all the glasses and contact lenses purchased by consumers in Switzerland. Fridrich Grumm of Kochoptik will be the first chairman of AOVS. Jürg Depierraz, an expert in communication and associations based in Bern, will act as general manager.
