, Center the MRP's, noting any deviations on the
weaker lens that my constitute vertical imbalance,
then read the distance and near powers in the circles,
noting any deviations outside of tolerances, and
finally remove the glasses and measure PD's and
heights.
When verifying a finished
pair of progressive-
addition lenses at the
lensometer, you have
identified the stronger
point. What are the next
steps to take and why?
a. Read the distance
powers in the distance
circle, noting any
deviations that may be
outside of tolerances, then
remove the glasses from
the lensometer and
measure PD's and height
b. Read the distance
powers in the distance
circle, read the add
powers, noting any
deviations that ma be
outside of tolerances, then
remove the glasses and
measure PD's and heights
c. Center the MRP's,
reading the powers and
noting any deviations that
may be outside of
tolerances, the remove
the glasses and measure
PD's and heights
d. Center the MRP's,
noting any deviations on
the weaker lens that my
constitute vertical
imbalance, then read the
distance and near powers
in the circles, noting any
deviations outside of
tolerances, and finally
remove the glasses and
measure PD's and
, When verifying prescribed prism
When is it necessary to
know the drop and inset of
a flat-top bifocal?
a. When verifying
prescribed prism
b. When ordering for a
sensitive person
c. When measuring a
patient's fitting height
d. When reading the add
power
Making any adjustments as the material cools
What is the most
important thing to avoid
when working with a
frame made of optyl?
a. Making any
adjustments as the
material cools
b. Heating the frame in
anyway
c. Getting the frame wet
d. Stretching the frame
beyond its shape and size
, Presbyopia
A 42 year old patient
presents to you
complaining of her eyes
being tired at the end of a
day of staring at a
computer screen, and the
patient is unable to read
the paper after dinner.
What is most likely the
problem?
a. Hyperopia
b. Presbyopia
c. Nystagmus
d. Phthisis
Palliative
What is a 1.5 diopter
horizontal prism for a
patient with a mild
esophoria known as?
a. Compound
b. Induced
c. Palliative
d. Slab-off
1.2 diopters
a +4.00 lens intended to
be positioned at PD of 30
mm was actually
manufactured at 33 m.
What is the amount of
prism induced by this
error?
a. 12 diopters
b. 0.75 diopters
c. 1.33 diopters
d. 1.2 diopters
