Technical Bulletin from a contact lens manufacturer. Portrait format, printed in blue on one side only of a single sheet of white paper. Describes a wide angle haptic lens, but with a transitional curve between the back central optic radius and the angle portion of the lens. The bulletin ends by suggesting that a basic trial set of twelve lenses is sufficient.
