The icon is changed to
, and the progressive
lens measurement screen is displayed by pressing
(single/ progressive lens selection switch).
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.

(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
3) Measurement of near point
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.
Progressive area
Take a measurement of near point. As shown on the right, move the lens slowly
to move the cross cursor (red)
according to
. 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

(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

The light wavelength for UV transmittance measurement is 375 nm. This does not measure the transmittance of a whole area of UV light.
6.7.1 Device Setting
Confirm that “UV Measure” is set as “On” before the measurement of UV transmission. In case of setting “UV Measure” as “Off”, neither UV transmission nor UV transmission
display area is displayed. If displaying UV transmission graph, set “UV Graph” as “On”.
The graph is displayed only in the progressive lens measurement mode.
(Refer to 4.2.1. Device Setting.)
6.7.2 Measurement of UV Transmission after Measuring Degree
The UV transmission measurement is performed after achieving an alignment of the lens and
pressing the Memory/Add switch to store the measurement values.
NOTE
At the time of progressive lens measurement, the UV transmission measurement is
performed after taking a measurement of far point
.
In case of taking a measurement again, clear the measurement values first by touching The values are cleared in order of degree of lens and UV transmission.
