Which feature uniquely identifies an executive bifocal?

• A. A large ridge across the full width
• B. A semicircular segment
• C. No ridge
• D. A thin line at the top

Answer: (A)

The feature that uniquely identifies an executive bifocal is a prominent boundary across the entire lens—the near-vision segment is large and the dividing line forms a wide ridge that runs full width. This visible, broad ridge sets executive bifocals apart from other bifocal styles, which may use semicircular or small segments, have no distinct line (blended), or show only a thin line elsewhere.
