A patient with a high nose bridge returns because their plastic frame slides down constantly. The MOST appropriate adjustment to improve retention is to:
Answer: Warm the nose area and close/narrow the bridge or increase pad arm inset to raise the frame on the nose
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.
When using a salt pan to heat an acetate frame, the optimal salt temperature range is approximately:
Answer: 130–140°F (54–60°C)
A salt pan maintained at 130–140°F provides sufficient heat to soften acetate for adjustment without scorching or deforming the material.
A patient whose temple is too long experiences the classic complaint of:
Answer: The frame sliding down the nose because the temples angle downward too much
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.
What is the risk of over-heating a zyl (acetate) frame during adjustment?
Answer: Surface bubbling, scorching, color fading, or permanent distortion of the frame
Excessive heat causes acetate to bubble, scorch, lose its surface sheen, or warp permanently, ruining the frame beyond repair.
An optician needs to increase the pantoscopic tilt on a metal frame. The correct approach is to:
Answer: Adjust the end piece angle with appropriate pliers while the frame is at room temperature
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.
A patient's frame has a cable temple (riding bow). Which patient population most commonly uses this temple style, and what adjustment consideration is unique to it?
Answer: Young children and patients who wear hearing aids; the coiled end must be carefully adjusted to clear the ear without pressure on the hearing aid
Cable (riding bow) temples coil around and under the ear and are commonly used for young children and hearing aid wearers; the coiled portion must be adjusted to avoid interference with devices or discomfort.
After adjusting a metal frame to correct a vertex distance issue, the optician should verify the final fitting by checking:
Answer: That the optical centers align with the patient's pupils, the frame is level, and the vertex distance matches the prescribed value
Post-adjustment verification must confirm that the optical centers are properly aligned with the pupils, the frame front is level, and vertex distance meets the prescribed requirement for the lens power.
