when calculating vertical prismatic imbalance, all of the following need to be considered except:
reading addition
in the following prescription, indicate the amount of conventional slab off needed to neutralize
the vertical prismatic imbalance. the reading level is 10mm.
Rx:-5.00-0.50x180
-2.75-0.75x180
add +2.50
2.0 A BU, OD
progressive power lenses require the following measurements in order to be accurately fit:
monocular PD and monocular segment height
of the lens materials listed below, which is the most impact resistant?
polycarbonate
a primary benefit of polarized lenses is:
they significantly reduce glare
the boxing method of measurement is especially useful since it can accurately locate the
_________ of the lens.

the patient has requested a pair of single vision lenses to use exclusively for reading at the near
point. what will be the power of these lenses?
+5.00-1.00x120
+4.75-0.75x110
most ophthalmic frames today are measured utilizing the boxing system of measurement. in
this system, the "B" measurement represents the _____________________.
the lens depth
a certain patient is found to have a monocular PD measuring R: 31mm and L:33mm. the box
measurement of the frame selected equals 52/18. lacate the major reference points (mrps) for
each eye.
R=4mm in; L=2mm in
when measuring a frame, the DBL is used to mean:
the least distance between lenses
which of the following best describes a semi rimless mounting?
a bridge with lens bars connecting the endpieces and temples.
when the measurement of the patient's PD is less than the GCD's of the frame, ideally, the
frame should be adjusted with
positive face form
a frame with a saddle bridge has been selected for a child than a comparable frame with
adjustable pads?
saddle bridge distributes the weight of the completed eyewear more evenly over a greater
portion of the nose area.
in the event of an accident, adjustable pads are more likely to cause injury.
a saddle bridge retains its adjustments better than a frame with adjustable pads.
excessive pantoscopic tilt may be reminded by:
angling the temples upward from the endpieces
2|Page
,in order to widen the distance between the nose pads of a frame it is necessary to bend the pad
arms:
outward
if the left is angled in, this will cause:
the left side of the frame to move out
a frame with pantoscopic tilt is fit so that:
the bottom of the eyewires are in closer than the top
a frame with retroscopic tilt is fit so that:
the bottom of the eyewires are out farther than the top
"bowing" the temples is a term used to describe which of the following situations?
curving the temples around the head
a patient enters your dispensary for a frame adjustment. you notice the bottom of the eyewires
touch the cheeks. to remedy this situation you will:
decrease the pantoscopic angle
one method of lowering the frame front is to:
spread the pad arms further apart
a patient complains of a sore nose caused by the back edge of the node pads. the possible
adjustment might be to:
flare the pads out more by spreading the back edge apart
bringing the pad arms closer together will result in:
raising the front
when the bottom of the eyewire is inclined outward, farther away from the face than the top,
this situation is known as _________________ tilt.
retroscopic
a certain frame contains 8 degrees of pantoscopic angle. ideally, the gaze will be directed
approximately _______________ above the optical center of the lens.
4mm
3|Page
, the epoxy frame material which is light in weight and contains "memory" which causes it to
revert to its original shape when heated is called:
optyl
the frame selection criteria most suitable for use with higher minus precription lenses is:
smaller eyesize
rounder shapes
heavier frame material
lightweight lenses
what would be the "theoretical" minimum blank size for the following frame and PD
combination? box measurement: A=54mm; DBL=20mm; ED=56mm; PD=63mm
67mm
the "B" measurement of a frame is equal to 54mm on the box. A FT 28 bifocal segment is fit at a
height of 23mm. where is the segment line positioned relative to the datum line of the frame?
4mm below
when calculating the actual minimum blank size, which of the following must be taken into
account?
possible imperfection along the periphery of the uncut lens such as chips or bubbles
blank size availability from the lens manufacturer
vertical multifocal segment decentration
when the measurements of a patient's PD and the GCD's are the same, ideally, the frame should
be adjusted with:
no face form
that part if the lensometer which is capable of measuring the amount of prism is the:
reticle
which of the following is a lensometer not capable of measuring?
base curve
the three closely spaced parallel lines come into sharp focus when the power drum reads -
2.50D and the axis wheel is set at 180 degrees. in order to bring the three widely spaced lines
into focus, the power drum must be moved to read -3.00D. prescription?
