Eye Care Centers of America is clearly focused on becoming the top eyewear chain. It owns or manages more than 400 optical stores in nearly 40 states. Its stores -- operating under the EyeMasters name and a host of others (Binyon's, Hour Eyes, Stein Optical, Visionworks, and Vision World) -- sell contact lenses, prescription eyewear, and sunglasses. The firm offers contacts and eyeglass frames under its own and designer brands, as well as one-hour service, on-site processing labs, and independent optometrists. Founded in 1984, the firm is a subsidiary of HVHC, itself a subsidiary of health care provider Highmark.
