C. Distance vision is minimized and near vision is maximized
D. Visual fields are significantly expanded
5. Skew distortion in progressive lenses is basically:
A. A front side induced shift in lens size
B. Caused by inaccurate pupillary distance measurements
C. An aberration that affects shape, which produces
unwanted astigmatism
D. The combination of a low-power distance Rx with
a high-powered add
6. Internal PALs place the progressive power on the _____ side of
a lens:
A. Front
B. Back
C. Base curve
D. Progressive
7. What are some factors that cause and effect the degree
of magnification:
A. Lens shape, lens power, and front curvature
B. Frame measurements, pupillary distance, and
optical center
C. Distance power as compared to near power
D. Intermediate power as compared to distance and
near power
8. By placing the progressive surface closer to the eye,
internal PALs:
A. Allow for more precise frame fitting and measurements
B. Change the front curve while the back curve remains
the same
C. Diminish the field of vision and decrease image stability
D. Expand the field of vision to create a wider
viewing section
9. Lens designs come in two forms, which are:
A. Hard finish and soft finish
B. Bifocal and PAL
C. Stock and semi-finished
D. Ovate and truncated
10. Traditional lenses are produced based on pre-molded lens
blanks that are:
A. Based on specific patient Rx requirements
B. Based on specific product ranges
C. Based on single-vision or multifocal parameters
D. Based on base curves, not lens blanks
11. Each free-form created lens starts with a:
A. Semi-finished single-vision lens
B. Progressive addition lens
C. Semi-finished multifocal lens
D. Stock lens
12. By moving aspheric curves to the back of the lens, each
curve is:
A. Sphericized specifically to the curve used on the lens
frontside
B. Prism ballasted for visual stability
C. Asphericized specifically to the curve used on the lens
frontside
D. Designed for single-vision lens surfacing
13. The first step in free-form processing is:
A. Blocking
B. Point of sale data entry is transmitted to the host
C. Polishing
D. Server processes information on which free-form lens
platform is used
14. Distortion caused by base curves that are too flat is called:
A. Pincushion
B. Presbyopic
C. Barrel
D. Prism
15. In a particular base curve and add combination, conventional
or front surface PALs will be totally accurate for:
A. Only one spherical Rx over the entire Rx range
B. Only one aspherical Rx over the entire Rx range
C. Only one single-vision Rx over the entire Rx Range
D. Only one PAL Rx over the entire Rx range
16. Internal PAL technology places a complex surface on the
backside of the lens by:
A. Joining aspheric and atoric design using a polisher
B. Processing one specific stock lens to create a
semi-finished lens
C. Fusing toric and progressive surfaces together into
one Rx-specific point file
D. Combining complex front side and back-side curves in
the generator
17. One primary candidate for internal PAL technology is:
A. Those with strong sphere prescriptions
B. Those with strong cylinder prescriptions
C. Those diagnosed with dry eye
D. Those diagnosed with keratoconus
18. When presenting internal PALs to patients, above all:
A. Thoroughly discuss all technical aspects of the lens
B. Mention AR only if a patient inquires about it
C. Put previous flat-top bifocal wearers back in flat-top bifocals
D. Have everyone in the practice wear internal PALs
19. When Fitting Succeed Internal Free-Form PALs:
A. Pupil should be between 50 and 75 percent of the
total frame height
B. Measure progressive height while patient is standing
with a PD ruler
C. Optical center should be marked on both the front
and back of the lens
D. Measure 1mm to 2mm lower than the manufacturer's
recommended fitting height if necessary
20. One way of marketing PALs suggested in this CE is:
A. Using dollars-off coupons
B. Display banners on your store signage
C. Incorporate lenses into your trunk shows
D. Run a full-page ad in the telephone book
