of segment).
According to prescription, enter lens layout data (FPD, near PD, and height of the optical center).
As the layout mode for the bifocal lenses, select passive (PAS) mode.

• When the lenses have an excessively short vertical diameter that the processing wheels
may come in contact with the lens cup, even when using a lens cup for half-eye lenses, the
yellow cup mark changes to red to warn the operator of a possibility of contact.
In such a case, change the layout mode to Passive and then block the lens. It is unnecessary to
change the lens layout data.
• If the lenses have a specific segment in shape (e.g. circular segment), the segment position
cannot be detected and the lenses cannot be blocked. Manually block such lenses (with
manual mode).
In such cases, mark the lenses using the lensmeter, and set the lens type to Manual.
