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 Answer - 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.
