For soft contact lenses, set the lens after removing moisture from the surface with a soft cloth.
CAUTION • Hold a contact lens with tweezers or fingers. Be careful not to damage the lens.
• Only use tweezers with round tips.
• Do not press the contact lens down with the lens holder.
It damages the contact lens.
5
Align the contact lens.
Align the contact lens, pushing its end lightly with
tweezers tips.
CAUTION • Avoid contacting the nosepiece while aligning the contact lens.
If not, the contact lens may fall.
6
In CL measurement, a SE value is displayed
along with the S, C and A measured data.
• SE (Spherical Equivalent) value
This is 1/2 of the cylinder value added to the sphere value. When a non-cylindrical contact
lens is measured and still a cylinder value is detected, the SE value will be more reliable
than the SPH value to know the total sphere value.
It reduces the error in the measured data made by the unintended cylinder value.

Marking
2.9.1
Marking at the optical center
Marking is performed to indicate the optical center position and axis direction.
• To measure PD of mounted lenses, mark a lens at the optical center of both right-eye lens
and left-eye lens. Measure the distance between the marked center points.
• For simple astigmatism lenses such as S 0.00 D and C -1.00 D or equivalent lenses, the
target cannot be moved in the bus direction.
Mark a lens at the geometric center in the correct direction.
1
Set a lens on the nosepiece.
2
Align the lens.
Move the lens until the target changes from
to
(cross) and then from
(cross) to
(large cross).
(large cross) shows that the lens is within
ø0.8 mm from the optical center where marking
is allowed.
3
If the lens contains cylindrical power, set the cylinder axis according to the prescription.
While watching the axis value, rotate the lens until the prescribed axis value is displayed.
When the “Auto RD S” or “Auto RD R/L” parameter
is set to “
” or “
”, the measured data will
automatically be fixed after the target is aligned.
Watch the axis value displayed to the top right of
the target.
When
(large cross) changes back to
(cross), align the target again.
For the axis of 90 or 180 , the shape of the target changes as shown on the right.
AXIS 90
42
AXIS 180
• When marking a cylinder lens in the bus direction, adjust the axis to 180 .
4
Hold the lens with the lens holder.
5
Mark the lens.
Press down the marking lever to mark the lens.
Three points in a line parallel to the lens table
are marked.
2
• Press down the marking lever slowly and lightly.
Pressing down firmly may damage the tip of the ink cartridge.
6
Remove the lens from the nosepiece.
To remove the lens, raise the lens holder lever
until it clicks.
• Do not touch the marked points.
Faded ink makes the cylinder axis hard to see.
• It is recommended to make its mark on the uncut lens with a marking pen to identify the
right side or left side of the lens or nasal side after marking.
• 䎃After marking the repellent or super repellent lenses, pull up the marking lever slowly so
that the tip of the ink cartridge gradually becomes off from the lens.
To do so causes fewer ink spread and the ink markings become easy to see.
