When a frame consistently sits crooked, with one lens higher than the other, what adjustment
should be made?
A. Bend the low temple downward
B. Bend the high temple downward
C. Lengthen both temples
D. Add pantoscopic tilt ✔Correct Answer-B. Bend the high temple downward. Explanation:
Lowering the high temple levels the frame. Key term: Temple adjustment = vertical correction.
What adjustment raises the frame when it sits too low on the patient's nose?
A. Spread pads
B. Narrow the bridge or thicken nose pads
C. Shorten temple bends
D. Add wrap angle ✔Correct Answer-B. Narrow the bridge or thicken nose pads. Explanation:
This lifts the frame upward. Key term: Nose pads = vertical height control.
What is the most effective way to minimize edge thickness in a -10.00 D prescription?
A. Select a small, round frame
B. Add pantoscopic tilt
C. Use a flat base curve
D. Increase vertex distance ✔Correct Answer-A. Select a small, round frame. Explanation:
Smaller, round shapes minimize lens edge thickness. Key term: Frame selection = optical design
consideration.
Which lens design reduces magnification in high plus prescriptions?
A. Toric
B. Aspheric
C. Spherical
D. Lenticular ✔Correct Answer-B. Aspheric. Explanation: Aspheric lenses flatten peripheral
curvature, reducing magnification. Key term: Aspheric = non-spherical optics.
Which adjustment reduces a frame slipping down during wear?
A. Add cable temples
B. Reduce pantoscopic tilt
C. Shorten temples
D. Flatten bridge curve ✔Correct Answer-A. Add cable temples. Explanation: Cable temples
curl behind ears to improve retention. Key term: Cable temple = wrap-around design.
, Which type of bifocal is most suitable for a machinist who needs to see near vision above and
below?
A. Trifocal
B. Progressive
C. Double D bifocal
D. Executive ✔Correct Answer-C. Double D bifocal. Explanation: Double D provides near zones
at top and bottom. Key term: Double D = occupational bifocal.
What adjustment decreases effective power of a plus lens?
A. Increase vertex distance
B. Reduce vertex distance
C. Increase pantoscopic tilt
D. Add wrap angle ✔Correct Answer-B. Reduce vertex distance. Explanation: Moving a plus
lens closer decreases effective power. Key term: Effective power = lens power at vertex.
If a PD is set too wide in minus lenses, what type of prism is induced?
A. Base-in
B. Base-out
C. Base-up
D. Base-down ✔Correct Answer-B. Base-in. Explanation: Wide PD in minus lenses creates
base-in prism. Key term: Prism induction = PD misalignment.
Which adjustment relieves temple pressure on the sides of the head?
A. Spread temples outward
B. Bend tips inward
C. Shorten temples
D. Raise pad height ✔Correct Answer-A. Spread temples outward. Explanation: Spreading
temples reduces side pressure. Key term: Temple spread = frame adjustment.
Which dispensing choice best reduces weight in a +12.00 D prescription?
A. Executive bifocal
B. Lenticular design
C. Polycarbonate spherical
D. Oversized aviator ✔Correct Answer-B. Lenticular design. Explanation: Lenticular lenses
reduce weight and thickness by limiting optical zone. Key term: Lenticular = reduced carrier.
Which adjustment corrects temples riding too high behind the ears?
A. Bend temple ends upward
B. Bend temple ends downward
C. Narrow bridge
D. Shorten temple tips ✔Correct Answer-B. Bend temple ends downward. Explanation: This
lowers temple position on the ears. Key term: Temple bend = comfort fitting.
Which lens choice minimizes peripheral distortion in strong plus lenses?
