Under ANSI Z80.1, what is the maximum allowable optical center vertical imbalance for a single vision lens pair with a power of -3.00 D sphere?
Answer: 0.67 prism diopters
ANSI Z80.1 allows a maximum vertical imbalance of 0.67 prism diopters for lenses up to ±3.375 D sphere equivalent.
Which of the following is a requirement of the FTC Contact Lens Rule enacted in 2004 and updated in 2020?
Answer: Sellers must obtain a verified prescription before selling contact lenses

An optician discovers that a patient's bifocal seg height was cut 4 mm lower than prescribed. The best course of action is to:
Answer: Reorder the lenses to the correct seg height specification

The purpose of a verification log in an optical dispensary is primarily to:
Answer: Document that finished eyewear meets ANSI standards before dispensing
A verification log documents that each pair of eyewear was checked against ANSI Z80.1 standards before being dispensed to the patient.
