GRADED A+ LATEST UPDATE.
If the wearer complains of the bifocal line being somewhat in his way
when driving, the problem may be alleviated by decreasing the distance
between pads.
True or False ANS >>> False
If the wearer complains that the glasses feel snug but still slip down the
nose, one likely cause is that:
A. The frame is too small
B. The bridge fit is tight
C. Pressure is being applied by the temple shafts anterior to the ear.
D. Pressure is being applied on the very tips of the temples. ANS >>>
Pressure is being applied by the temple shafts anterior to the ear
,If both notepads press the nose or indent too much, what is probably
not a possible cause?
A. Pads too small for frame weight
B. Temple spread is not even
C. Pads too close together
D. Temple tension too great ANS >>> Temple spread is not even
To eliminate a gap between the lens and a metal eye wire, the best
alternative is to:
A. Place a strip of lens liner at a point exactly opposite the gap
B. Place a strip of lens liner in the gap area
C. Heat the lens in the frame and allow it to cool at room temperature
D. None of the above methods are satisfactory
E. All of the above methods are satisfactory ANS >>> Place a strip of lens
liner at a point exactly opposite the gap
The larger the frame difference --------- the lens shape
A. Rounder
B. More squared off
C. Narrower
,D. Wider ANS >>> Narrower
(Frame Difference=A-B)
Which is the most favourable alternative to a 50/20 frame for
measuring bifocal height when that particular size is not available?
A. 52/18
B. 50/18
C. 48/20
D. 50/22 ANS >>> 48/20
(would want bridge to stay the same)
When the frame front is tested for four-point tough, but only touches
on the two temporal sides, the frame --------
A. is skewed
B. has face form
C. is out of coplanar alignment
D. has X Ing
E. none of the above ANS >>> Has face form
, Which of the following errors will not be detected by a four-point touch
test?
A. X-Ing
B. Excess face form
C. Skewing
D. All of the above can be detected using a four-point touch ANS >>>
Skewing
It is unnecessary to use heat in adjusting a Zyl frame when:
A. Bending the endpieces
B. Changing the bridge area
C. Bending the temple earpiece
D. Changing the autoscopic angle ANS >>> Changing the autoscopic angle
If you didn't adjust the eye piece on the lensometer and the power
drum reads +0.25 when the target lines are clear and focused. What do
you expect the true readings for this pair of glasses be? O.D. -1.75 OS
+1.75
A. -1.50, +2.00
B. -1.75, +1.75
