NOCE Dispensing and Fitting Procedures 2

Question 1

A patient's glasses slide down the nose constantly. Which adjustment is MOST appropriate?

Accepted Answer

Add nose pad armature tension or adjust pad angle

Answer

Adjusting nose pad tension or angle increases friction and grip to prevent the frame from sliding down.

Question 2

Which fitting measurement determines the height at which the progressive addition lens corridor should be placed?

Accepted Answer

Segment height (fitting height)

Answer

The segment (fitting) height marks the position of the pupil center relative to the frame bottom to align the progressive corridor correctly.

Question 3

When dispensing a frame with a high base curve, which optical effect is most important to consider?

Accepted Answer

Wrap-induced oblique astigmatism

Answer

High base curve wrap frames introduce oblique astigmatism when the lens plane is not perpendicular to the line of sight.

Question 4

A patient complains of facial pressure behind the ears after wearing new glasses for one hour. The FIRST adjustment to check is:

Accepted Answer

Temple length and bend position

Answer

Discomfort behind the ears is usually caused by temples that are too short or have their bend positioned too far forward.

Question 5

For a patient with a high minus prescription, which lens design choice reduces edge thickness the most?

Accepted Answer

Small frame with high-index lens

Answer

A smaller frame minimizes the lens diameter needed, and a higher-index material bends light more efficiently, both reducing edge thickness.
