The organizers of the China International Optics Fair in Beijing were expecting around 700 exhibitors from 19 countries at its 22nd edition, although its dates of Sept. 16-18 conflict with those of the big international Silmo fair in Paris. They said that buyers from big chains such as Specsavers, Hans Anders and National Vision had confirmed their visit to the show. Many executives of major Italian company that are not exhibiting at Silmo have excused themselves for their absence from the Paris show because of the fair in Beijing. CIOF was due to showcase about 600 local brands and 250 international ones including Aoyama, CIBA Vision, Oxibis and Silhouette.
