Celebrating its 10th anniversary, the International Fair of Eye Optics and Ophthalmology (OPTA) due to be held in Brno next Feb. 20-22, has given a 10 percent discount to all the exhibitors who have taken part in all its previous sessions. All visitors will have visible tags that will give exhibitors more information on who enters their stands. Held under the auspices of AEUSCO and ECCO, a conference will focus on changes in regulations related with the enlargement of the European Union. The Czech exhibition has become the biggest event of the kind in Central Europe.
