Question 1

A patient's frame sits too low on the nose, causing the optical centers to be above the patient's pupils. What adjustment is most appropriate?

Accepted Answer

Raise the nose pads

Answer

Raising the nose pads lifts the frame so the optical centers align properly with the patient's pupils.

Question 2

When measuring pupillary distance (PD) for a patient with significant facial asymmetry, which method is most accurate?

Accepted Answer

Monocular PD from each eye to the nose bridge

Answer

Monocular PD measurements account for facial asymmetry by measuring each eye independently from the nose bridge.

Question 3

A patient complains of a 'swim' sensation after receiving new progressive lenses. The most likely cause is:

Accepted Answer

All of the above

Answer

Swim sensation in progressive lenses can result from incorrect PD, improper fitting height, or excessive pantoscopic tilt, as all affect the progressive corridor alignment.

Question 4

The standard vertex distance used when prescribing trial frame refraction is:

Accepted Answer

12mm

Answer

The standard vertex distance for trial frame refraction is 12mm, and prescriptions are compensated if the actual vertex distance differs significantly.
