Cause 1
If progressive area is expanded into distance viewing zone, it is
difficult to find the distance viewing zone.
Countermeasure
Place the cross mark as close as to distance viewing zone target
center, and press ‘MEM’ button.
Cause 2
If distance viewing zone is near the upper frame, it is difficult to
find.
Countermeasure
Pull up the lens holder, and find the distance viewing zone
center while pulling the frame.
④ When it is difficult to find near viewing zone.
Cause 1
If near viewing zone is located near the bottom frame, it is difficult
to find. Countermeasure: Pull up the lens holder, and find the
near viewing zone center while pulling the frame.
Cause 2
If the progressive area continues after the near viewing zone
center, it is difficult to find.
Countermeasure
Adjust so the value minimized, and save by pressing ‘MEM’ button
when progressive power reaches maximum. (Measurement can be
slightly different with actual values.)
⑤ When progressive measurement is incorrect. (Especially when near viewing zone
power is higher by more than –4D.)
Cause 1
It can be because the lens was picked up during measurement.
Countermeasure
Pull down the lens holder to fixate the lens and maintain the angle.
Move the lens left-right or upward/downward.
