Abstract:

The report covers effort conducted under three tasks material development design analyses and breadboard studies. The materials development was directed toward the development of a polycarbonate ophthalmic lens coated with an abrasion resistant material. Epoxy melamine coatings and commercial coatings were examined. The design analyses were twofold. First, a requirements analysis was conducted to establish physiologic, ophthalmic, optical, and military requirements. Second, system requirements were analyzed, leading from the project goals to the development of a preliminary design. Breadboard studies were begun to evaluate mold materials, method, and the various types and grades of polycarbonate. Compression molding processes for polycarbonate were evaluated leading to the development of an acceptable breadboard molding cycle. Breadboard compression molding equipment was put into operation. Trial lenses were produced and evaluated.
