Active mode
This is for blocking a lens at the optical center.
Auto processing mode
In this mode, the bevel curve and bevel position are automatically calculated by the computer for their best
values of processing.

Eye point layout
This is a form to input the eye points as the optical center by the distance measured from the nasal and bottom
side of lens outline. This form serves to specify the position of the eye point, which is marked on the dummy
lenses, as the optical center.
FPD (Frame Pupillary Distance)
This represents the distance between the right and left rim centers.
The rim centers are calculated by boxing system.
Goggle type frame tracing
This is a process to trace a sharply warped frame, such as goggles. The stylus may often come off the groove
of such a frame. In such cases, set only one rim in the tracing unit and hold the frame temple on the other side
while tracing.
Processing for frame changing mode
This is a process to edge a lens, which has already been mounted on one frame, in order to fit it into another
frame.
Guided processing mode
In this mode, bevel curve and bevel position can be specified manually.
