United Lens Company has a long tradition of service to the optical industry, and our commitment is ongoing to the industry, our customers and our employees. Since our founding in 1916 by Fileno DiGregorio, ULC has been under the same continuous family ownership, becoming the only true vertically integrated company in the optical industry. What separates United Lens from other suppliers is that we are the only company that can form, anneal, machine, polish and coat all at one facility.
