The cylinder axis wheel of the lens meter is engraved with which of the following measurements? 2. Electricity requirement for an edging workshop should include all the following EXCEPT.
Understand the Problem
The image presents two multiple-choice questions related to optometry or optical workshop practices. The first question asks about the measurement increments on the cylinder axis wheel of a lens meter. The second question asks about electrical requirements for an edging workshop, specifically which of the listed options is NOT a requirement.
Answer
12. a. 0 to 180° in 1° increments. 13. a. at least four outlets are required on the optical bench.
The answer to question 12 is a. 0 to 180° in 1° increments. The answer to question 13 is a. at least four outlets are required on the optical bench.

More Information
A lensmeter, also known as a lensometer or vertometer, is an ophthalmic instrument used to verify the correct prescription of eyeglasses or contact lenses. For the electricity question, the number of outlets needed depends on the equipment, but it is not a basic requirement to have at least four outlets on the optical bench.
