What are additional curves on the lens that surround the optical zone called?

  1. Base curve radius

  2. Peripheral curves

  3. Segment heights

  4. Trifocal additions

The correct answer is: Peripheral curves

Peripheral curves are additional curves on the lens that surround the optical zone. This is in contrast to the base curve radius, which refers to the overall curvature of the lens. Segment heights and trifocal additions are also not accurate as they refer to specific features not related to additional surrounding curves on the lens.
