2. A truncation is used on a rigid The answer is A.
gas permeable contact lens to
help enhance the performance of A lens is truncated by removing a segment of the
which type of design? lower edge of a contact lens. This creates a straight
edge that interacts with the lower lid and aids in
A. Bifocal lens positioning. Of the lens designs listed in the
