Which statement correctly describes how the progressive lens markings are used?

• A. Will help the dispenser make the final frame adjustments.
• B. Identify the lens brand
• C. Determine the lens color
• D. Indicate tint level

Answer: (A)

Progressive lens markings serve as guides for the dispenser when fitting and edging the lens in the frame. They indicate where the lens’ optical centers and progression zones are so the lens can be oriented correctly with respect to the wearer’s eyes, frame height, pantoscopic tilt, and pupil position. This ensures that the distance, intermediate, and near zones line up properly with where the wearer looks through the frame. They’re not used to determine tint, color, or to identify the lens brand—the practical purpose is accurate alignment and final frame adjustments, which is why this choice is the best.
