EAST SYRACUSE, N.Y.—Essilor of America announced today that it has acquired a majority stake in US Optical, an East Syracuse, N.Y.-based wholesale optical laboratory with around $35 million in annual revenue.

“This partnership will help to complement Essilor's U.S. offerings and broaden the distribution of Varilux lenses and other value-added products,” Essilor said in a statement.

US Optical was founded in 2008 by three brothers, Ralph, Ronald and Robert Cotran. It is the second largest independent U.S. wholesale lab, according to Vision Monday’s 2015 Top Labs Report.

An Essilor spokesperson confirmed that the Cotrans will continue to manage US Optical.

This is the second major transaction between the Cotran brothers and Essilor. In 1999, the brothers sold Optogenics, a Syracuse, N.Y. wholesale lab they founded in 1986, to Essilor.
