Emerging Vision, parent company of the Sterling Optical retail chain, had a 13.5 percent drop in sales in 2009 to $62.1 million, and its net loss worsened to $2.5 million, against a loss of $88,000 in 2008. The U.S. company also owns two buying groups, Combine and The Optical Group, that had a 12.5 percent drop in turnover to $50.7 million. Royalties in the franchise division declined by 11.4 percent to $5.5 million, and sales at company-owned stores plunged by 40.9 percent to $2.2 million, attributed to a decrease in the number of stores. Comparable store sales fell by 141 percent. Emerging Vision established a $4.25 million non-revolving line of credit with Manufacturers and Traders Trust at the end of March. It extends an earlier agreement through April 2011, and waives Emerging Vision's non-compliance with previous terms.
