Which of the following terms is used to designate a lens without power?

  1. Cylindrical

  2. Plano

  3. Bifocal

  4. Aspheric

The correct answer is: Plano

Simply put, a plano lens has no power, meaning it does not correct for near- or farsightedness. Cylindrical, bifocal, and aspheric lenses all have some level of corrective power, making them incorrect choices for this question. Plano lenses are often used as a base for adding power in stronger prescriptions.
