The optician has just neutralized an unknown power lens with test lenses.
The test lens used to neutralize the power in the vertical is +1.00D and
the test lens used to neutralize the power in the horizontal is a +1.50D.
What is the Rx of this lens? (Note: these test lenses were used alone for
each meridian, not superimposed. Using test lenses is another way to
neutralize the lens power and can be used instead of the lensometer.)

B. +1.50 -0.50 x 180
C. -1.00 -0.50 x 90
D. +1.00 +0.50 x 90
Verified Answer --1.00 -0.50 x 90

Verified Answer -0.5mm In

Rx of a patient is: OD +4.00 +1.00 x 45 OS +6.00 +2.00 x 80
He chooses a new frame. You take the PD and that is 72/68. You check
his old glasses. The Rx is OD +4.50 +1.00 x 35 OS +6.75 +2.00 x 90 and
the MPD is 65. There is no mention of PPD in the new Rx and the patient
has no complain. What would you do?
A. Fill up the order form with the new PD (72) and order the lenses
B. Tell the patient to come back another day for checking the PD
C. Fill up the order form with the previous PD (65) and order the lenses
Verified Answer -Fill up the order form with the previous PD (65) and
order the lenses
Rx: OD +2.00 +4.00 x 45 OS +3.00 +1.00 x 90
A=52 DBL=18 PPD=66
The lab decenters the lenses the wrong way. The prism imbalance will
be:
A. 1.6 prism diopter
B. 3.2 prism diopter
C. 1 prism diopter
