Uncuts

Uncut entry in Rx-Universe is similar to entry of other jobs, with a changes to the handling of certain fields.

When entering an order, the job type can be "Full Job" (which includes frame measurements), "Uncut no frame", or "Uncut with frame".

"Full job" and "Uncut with frame" require either box measurements or a frame trace to be entered for the order.  If frame measurements are used, PD and Seg Height (both relative to the frame) can be specified for the order.

To process an uncut with no frame measurements, select "Uncut no frame" as the Job Type:
      

After choosing the lens style, material, etc., certain fields will be greyed out and not available for uncuts, depending on the lens style selected.

Single Vision - can enter horizontal and vertical decentration.  Prism will be calculated to move the OC from the blocking center (GC of the blank) to the point specified by the decentration.

f a PD is entered, instead of a decentration, the user will be warned:
       

This is because there is frame with which to determine decentration using the interpupillary distance.

 

Non-Progressive Multifocals (Flat Tops / Round Segs / Executives)

For multifocals, the user may specify the inset desired (the horizontal distance between the distance OC and the segment), and the BOC (below optical center), the vertical distance from the OC to the top of the segment.  The distance PD and SegHt fields are inaccessible, but are automatically calculated based on the Inset and BOC, and the particular blank that is used.

For example, a Flat Top Bifocal, uncut to 65mm, with an inset of 2mm and a BOC of 4mm would be entered as:
         

The PD and SegHt fields, above, are calculated based on the lens blank that is used.  In this case, the lenses used were VE 75mm:

The PD (or decentration) is calculated as BSI - Inset = 6.5 - 2.0 = 4.5mm.  The OC is thus located in 4.5mm from the GC of the blank (also the blocking center).

The SegHt is calculated as Crib/2 - BSD = 65/2 - 6.5 = 26.0 (the top of the segment is 6.5 down from the blocking center, since the lens is blocked on geometric center.

Labs can set up defaults for uncuts for the Inset and BOC values, in the System Parameters, on the Orders2 tab:
