CHARENTON-LE-PONT, France—Essilor reported last week that it has made three new acquisitions that intended to boost external growth.

Essilor International's subsidiary Essilor Canada has acquired a majority stake in Westlab Optical, a prescription laboratory located in Montreal, which generates sales of $4 million Canadian. The partnership focuses primarily on developing the company's portfolio of combined lens/frame packages.

Separately, the lens maker is accelerating its development in Eastern Europe by setting up operations in Bulgaria. Its new subsidiary Essilor Bulgaria Eood has acquired Optymal Ood, which currently distributes Essilor lenses and instruments in Bulgaria and has sales of nearly €1 million. According to Essilor, the acquisition will enable it to enhance its competitive position in the fast growing corrective lens market, especially the progressive lens segment.

Additionally, following the acquisition of MGM in 2005, Essilor is strengthening its presence in Puerto Rico by acquiring Rainbow Optical Labs, a prescription laboratory with $3 million in revenue.
