The U.K.'s Federation of Manufacturing Opticians (FMO) is inviting for the first time companies outside the U.K. to become members of the organization. Membership had been limited until now to British firms and to the British subsidiaries of foreign companies. Members can belong to any of FMO's focus groups for frames, lenses and technology. They can use its prestigious office in Paddington and participate in meetings with other business leaders. They can obtain discounts for participation in Optrafair, the national eyewear show, which will take place for the first time in London a few weeks from now.
