Frames included in the Frame of Choice program are listed in Attachment 1. Availability of lenses, other than CR-39, is subject to laboratory inventory and capability. FOC will not be requested in lieu of industrial safety glasses. Clinicians are encouraged to recommend a smaller frame to the patient to reduce edge or center thickness. Crown glass lenses will not be available in the FOC program.
Crown glass is much less impact resistant than other lens material.
Requests for CTs less than 2.0 mm will require justification and will normally be fabricated with Polycarbonate lenses. Point of Contact .
