USING THE INSTRUMENT
MEASURING A PROGRESSIVE LENS FOR DISTANCE VISION
(EXCLUDING HORIZONTAL PRISIM PRESCRIPTION LENSES)
1 During distance vision measurement, a graphic display, as shown below, is shown on the
screen.
Move the lens slowly from the progressive zone at the lens center to lens
top, and bring the “+” into the circle .
2 When the distance vision measurement is obtained and saved, the
screen automatically changes to the near vision measurement display.
(The distance vision region can be easily detected, as you repeat moving
and stopping the lens little by little at measuring.)
By pressing the Memory button , you may manually store the result of distance
vision power measurement. The screen will then switch to the near vision mea-
surement.
When is selected as the default setting, the result
of the distance vision measurement is not automatically stored. With this setting,
you must press the Memory button to save the distance vision.
For high-power lenses, sometimes the distance vision region cannot be easily
detected. In this case, obtain the measurement in the approximate position that is
shown on the above, and then press Memory button .
For horizontal prism prescription lenses, press the MEMORY button at the dis-
tance refference point.
