USING THE INSTRUMENT
MEASURING AN UNPROCESSED PROGRESSIVE LENS
As each unprocessed lens has a mark on the measuring point. Do measurement on the
mark position. For measurement, follow the procedure of “Measuring a progressive lens”,
“measuring a progressive lens for distance vision” and “Measuring a progressive lens for
near vision”.
MODE TO MEASURE THE DIOPTER POWER OF LENSES WITH THE CONCAVE SIDE UP
1 Set .
2 Set the lens with the concave side down as
usual, align the distance vision region, and
press the MEMORY button .
3 Set the lens with the concave side up, align the
distance vision region, and press the MEMORY
button .
4 Leaving the lens with the concave side up, align
the near vision region and press the MEMORY
button .
The measuring point for the distance or near vision region may be narrowed by
marks. Take care that the luminous flux may not be shaded during measurement.
ADD values will flicker when the luminous flux is shaded by marks or off the pro-
gressive zone at the time of measuring the near vision region. An EX lens may not
be provided with accurate measurements when measured in the boundary.
