41. An
Optician can optimize the fit of a frame with Gross Frame Alignment first,
followed by Subtle Frame Adjustments. The Subtle Frame Adjustments are
accomplished by:

the hands.

their final inspection.

Patient complains of their eyeglasses being too loose while you are performing
a zyl frame adjustment, you can see spacing, and you can feel gaps where
there is no contact between the Patient's mastoid and both temple ends.
To remedy this situation you will:
a) bend the temples closer to the top of the ear for a tighter fit.
b) have the Patient shake their head to see if any adjustment is really
necessary.
c) handcraft the temples using your hands, with the aid of a frame warmer,
to reshape the temples to match the curves of the Patient's skull for
total contact.
d) straighten the temples so they fit, library style, around the
back of the Patient's head.
43. With
your assistance a Patient selects a new frame which fits squarely with
standard alignment. While measuring the patient for multifocal lenses
it is determined that the left eye is 2 mm higher in relation to the frame-face
alignment. To compensate for this anomaly you will:
a) ignore the anomaly and order the seg heights to be equal in both lenses,
as usual, so they appear to be equal upon anyone's inspection.
b) ignore the anomaly and say nothing so that the Patient is not embarrassed.
c) align the frame so that the left eyewire will be higher, making the
segs vertically equal even though the frame is tilted off axis.
d) advise Patient that eye and ear anomalies are common, and that you
will order the left reading segment 2 mm higher than the right so that
the they can gaze through the same reading portion of each lens simultaneously
for a more balanced visual experience.
