lens measurement screen is displayed by pressing
(single/ progressive lens selection switch).
NOTE
In case that Auto Prog is set as “On”, the lens is automatically judged whether the lens
is a progressive lens or not.
Set the lens in the center region of the progressive zone. It starts the auto judgment of
the progressive lens. When the lens is identified as a progressive lens, the screen is
switched to the progressive lens measurement screen. If not, the measurement screen
remains as the single focus lens measurement screen.
When the ADD value is small (less than 1D), the auto detection may not be performed.
Also, if the progressive zone cannot be found at where the lens is set, the auto detection
may not be performed.
In these cases, move the lens back and forth, and right and left slowly.
When the ADD value is small (less than 1D), the framed lens is small, or the lens is dirty
or has some flaws, the far point and near point may not be detected automatically. In
such case, take a measurement manually.
29
(3) Measuring procedure of progressive lens (when N.AT is selected for ADD Measure)
1) Detection of progressive zone
First, find the progressive zone by moving the lens back and forth, and right and left slowly.
The cross cursor (screen shown below) appears when the progressive zone is found.
NOTE
Press the Memory/Add switch in case that the progressive zone cannot be detected
because ADD value is small etc. It switches to the measurement screen of the far point.
2) Measurement of far point
Take a measurement of far point. Move the lens toward the
device so as that the center of the alignment mark overlaps
with the cross cursor.
The color of the cross cursor is changed to blue by pressing
the Memory/Add switch after they overlaps.
At this time, the measurement values of the far point
are stored.
NOTE
When “ADD Measure” on the Setup screen is set as “F/N.AT”, it is detected
automatically and the measurement values are stored in memory.
3) Measurement of near point
Take a measurement of near point. As shown on the right,
move the lens slowly to move the cross cursor (red)
according to
Progressive area
. If it goes out of the progressive zone, the
cross cursor moves right or left. If it goes out of the
progressive zone, bring it back to the zone and move the lens
toward near point.
NOTE
The cross cursor on the screen indicates the actual
measurement position on the lens. For example, if it
goes to the right side of the lens which is out of the
progressive zone at the time of moving from far point
to near point, the cross cursor is displayed on the
right deviated from the progressive zone.
Perform the alignment carefully when it comes closer to the
near point and
starts blinking. Once the near point is
detected, it blips. The cross cursor is fixed at the near point
and its color changes to blue. When the near point is attained,
the ADD value is stored in memory automatically.
※Another ADD value (Ad2) can be stored in memory anywhere
by pressing the Memory/Add switch after measurement.
The progressive judgment screen appears again by setting
the lens for the left eye and touch
after completing
the measurement. Take a measurement of the left lens in the
same manner as right lent.
※Measurement can be started from either right or left lens.

(4) Display of ADD value and assessment graph, and manual operation
(when “Manual” of “ADD Measure” is selected)
When setting “Prog. Graph” as “On” on the Setup screen, the graph is displayed on the
progress lens measurement screen.
Depending on the type of lens, it may be difficult to detect each point automatically even
though normally the near and far points are detected automatically. In such case, take a
measurement manually by reference to the ADD value and assessment graph.
To take a measurement of far point manually, carry out the alignment in the same manner
as the auto measurement.
For the measurement of near point, press the Memory/Add switch where the ADD value is
the highest while the alignment cursor stays in the progressive area.
The near point is where the assessment line moves closer to the Y coordinate. Therefore,
carry out alignment by reference to the shape of the graph and blinking of
