4.4.3 Blocking bifocal lenses
When BF (bifocal) is selected for the layout mode, a lens is blocked at the specified value UP
and OUT position from the top line center of the segment.
Be sure to block the lens as instructed below since the edger processes the lens with the specified
values. See “4.3.2.2 Layout of bifocal lenses” (p. 4-9).
Block a lens at the position 5 mm above and
5 mm outside from the top line center of the
segment with a lens cup (When using the
NIDEK centering device CE-1).
NOTE
• The edger is factory-configured so that a lens is blocked at the position 5 mm above
and 5 mm outside from the top line center of the segment with the NIDEK centering
device CE-1. (The provided layout mark of the segment on the screen of the CE-1
allows an operator to easily block a lens at 5 mm up and 5 mm outside.) When using
the centering device of another manufacturer, it is possible to specify appropriate values
to the device. See “5.2 Parameter Settings (p. 5-2)”.
