EyeCare Partners (ECP), a U.S. network of medical optometry and ophthalmology practices, has bought Nationwide Vision, an Arizona-based vision care provider, from the Refac Optical Group, as first reported by Vision Monday. The disposal will enable Refac to focus on U.S. Vision, an eyewear wholesaler and retailer. The terms of the transaction were not disclosed. The acquisition lifts the nationwide network of ECP, which is backed by the private equity firm FFL Partners, to about 450 points of service, according to VMail. Refac, which in turn is owned by the private equity firm Acon Investments, indicated that the sale of Nationwide puts it in a better financial position and will allow it to focus solely on U.S. Vision, which operates over 400 optical locations in the country and is present in JC Penney, Boscovs, Meijer and Army & Air Force Exchange Service (AAFES) locations. The chain will take over five Nationwide Vision stores in Nevada and North Dakota. U.S. Vision also runs a 72,000-square-foot laboratory outside Philadelphia with the capacity to produce more than three million complete pairs of eyeglasses annually.
