4.5.3 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 segment.
Be sure to block the lens as instructed below since the edger processes the lens with the specified
values. See “4.4.2.1 Layout of bifocal lens” (p. 4-15).
Block a lens at 5 mm up and 5 mm outside
position 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 5 mm up and 5 mm outside
position with the NIDEK centering device CE-1. (The provided layout mark of 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 the other manufacturer, it is possible
to specify appropriate values to the device. See “5.2 Parameter Settings” (p. 5-2).
