Which design is more likely to be described as moving with the eye to align reading zones?

• A. Simultaneous design
• B. Translating design
• C. Front surface aspheric
• D. Back surface aspheric

Answer: (B)

The idea being tested is how a lens can keep the reading portion aligned with your gaze as you shift from looking straight ahead to reading. A translating design does this by having the near-reading segment physically move relative to the distance portion as you shift your gaze downward. In this setup, the near zone slides into position under the pupil when you look down to read, so the reading area is consistently aligned with your line of sight. Surface shapes like front or back aspheric describe how the lens is curved, not how the reading zones track your eye, and a simultaneous design refers to having distance and near information present at once in the field of view rather than to the lens moving to align the zones.
