ABO NOCE Basic Opticianry Frame Adjustment Techniques by Material 5

Question 1

A patient with a high nose bridge returns because their plastic frame slides down constantly. The MOST appropriate adjustment to improve retention is to:

Accepted Answer

Warm the nose area and close/narrow the bridge or increase pad arm inset to raise the frame on the nose

Answer

Warming the bridge area of a plastic frame allows the bridge or built-in pads to be repositioned to better grip the nose and reduce sliding.

Question 2

When using a salt pan to heat an acetate frame, the optimal salt temperature range is approximately:

Accepted Answer

130–140°F (54–60°C)

Answer

A salt pan maintained at 130–140°F provides sufficient heat to soften acetate for adjustment without scorching or deforming the material.

Question 3

A patient whose temple is too long experiences the classic complaint of:

Accepted Answer

The frame sliding down the nose because the temples angle downward too much

Answer

When a temple is too long, the bend rides too far down the ear, causing the temple to angle the frame downward and making it slide forward on the nose.

Question 4

What is the risk of over-heating a zyl (acetate) frame during adjustment?

Accepted Answer

Surface bubbling, scorching, color fading, or permanent distortion of the frame

Answer

Excessive heat causes acetate to bubble, scorch, lose its surface sheen, or warp permanently, ruining the frame beyond repair.

Question 5

An optician needs to increase the pantoscopic tilt on a metal frame. The correct approach is to:

Accepted Answer

Adjust the end piece angle with appropriate pliers while the frame is at room temperature

Answer

On metal frames, pantoscopic tilt is adjusted by rotating the end piece (where the temple connects to the front) using angling pliers at room temperature—no heat is needed.
