SOUTH WINDSOR, Conn.--Gerber Coburn and Essilor Instruments, a division of Essilor International, Paris, have extended their distribution agreement for another three years.

Under the terms of the agreement, Gerber Coburn will continue to distribute Essilor-manufactured lens finishing products exclusively in North America and Australia and market-specific products worldwide. Gerber Coburn will also continue to work closely with Essilor Instruments to develop and manufacture the industry’s most advanced ophthalmic lens finishing systems.

Gerber Coburn has distributed Essilor lens finishing systems for nine years.

The move follows by a day Essilor Instruments’ acquisition last week of National Optronics, a supplier of edging systems based in Charlottesville, N.C.
