Multifocal Lens
1. Measure the far point by aligning the lens by centering the
green Cross Cursor mark in the center of the target by mov-
ing the lens. The message “Alignment OK” will appear on the
screen when the lens is aligned properly.
2. Press the Memory/Add button to store the Sphere, Cylinder,
Axis and Prism measurements.
Note:
If “Auto Memory” in the Setup screen is set to “On”, then
the lens will automatically be measured once the Cross
Cursor is centered in the middle of the Alignment Mark.
Note:
When the optical center is found, either automatically or
by pressing the Memory/Add button, the Cross Cursor will
change from green to blue, and the measurement box will
change from gray to blue. Refer to Figure OP-10.
3. To take a measurement of the Near Point, press the Mea-
surement/Add button. "Add1" will appear in gray beneath the
stored values. Refer to Figure OP-10
4. Take a measurement of near point by moving the lens so that
the near point (near-sight segment) comes to the center of the
lens stand.
Note:
A measurement can be taken even if the messages “Align-
ment OK” and ”Marking OK” are not displayed.
5. Store the ADD value of the near point (near-sight segment) in
memory by pressing the Memory/Add button. The gray "Add1"
box will change from gray to blue, indicating the value is
stored. Refer to Figure OP-11.
Note:
If a trifocal lens is being measured, press the Measure-
ment/Add button again and “Add2” will be displayed in
gray, indicating the unit is ready to measure the second
segment. Once the second segment is aligned, press
the Memory/Add button to save the measurement. The
"Add2" box will change from gray to blue, indicating the
measurement is stored. Refer to Figure OP-12.
6. Switch to the left lens by pressing L/R.
7. At this time, the measurement result of the right lens remains
on the screen.
Note:
The active lens being measured ("LEFT" or "RIGHT") will
be displayed in blue, and the inactive lens will be displayed
in gray.
