3. OPERATING PROCEDURE : Progressive Power Lens Measurement
♦
Progressive power lenses for vertically narrow frames
When the height of the processed lens is small and near
portion is not intact, the display changes to alert that the
correct near power has not been measured.
When the edge of the lens is reached before the near por-
tion is detected, a small lens image is displayed on the
screen. At this time, the lens image and measured value of
add power are displayed in orange.
The near add power is locked in by auto read func-
tion, and measurement completes.
An exclamation mark is added to the add power on the
printout.
When the height of the processed lens is short and near portion is not intact, add power cannot be
measured with usual auto read function.
