Certified Paraoptometric (CPO) Practice Exam 2026

Question: 1 / 420

What part of the frame extends back alongside the head and over the ear?

Fitting Triangle

Temple

The correct answer is the temple. The temple is a crucial component of eyewear, extending from the front of the frame, where the lenses are located, back along the side of the head and over the ear. Its design helps in securely holding the glasses in place while providing comfort and stability during use.

The fitting triangle refers to the area that encompasses the proper fit of the frame on the wearer’s face but does not directly extend to the back of the head. The eyewire is the part of the frame that holds the lenses in place, which is different from the area that extends to the sides of the head. The lens itself is the clear part that the wearer looks through and does not cover the area behind the ear. Hence, the temple is the only option that accurately describes the part of the frame that extends back alongside the head and over the ear.
