The right answer can mean 6 points in the clinical domain. Answer: Even though all these lenses correct vision in some way or another, (e) is the correct answer. Prescription glasses and reading glasses (whether prescription or not) are considered corrective lenses. But "a magnifying glass is not considered an example of a corrective lens," the Centers for Medicare & Medicaid Services explains in the M0390 response-specific instructions.

(a) prescription glasses,
(b) a magnifying glass,
(c) reading glasses from a drug store,
(d) all of the above,
(e) only (a) and (c).
