Trace Offset Notes 11-12-2012

Key Points ?Optifacts labs can put the trace offset data in their systems to adjust all jobs that come in for the ECP ?Other lab systems cannot do that, such as DVI Labs cannot retain this information so the Trace Offset features support these types of lab customers. ?The lab will tell the user what their offset is. ?Done by the bill to, ship to ?User sets up 1 time only, by lab. ?User can edit it if needed ?Instructions are on the order entry page Walman Optical has enabled this feature on their labs and they will slowly communicate this to their VisionWeb users- effective 11-16-12 You can refer users to the Walman Helpdesk: The Optical Help Desk is available M-F, 8:30am ? 5:30pm CST.

A tracer that accepts this record should be able to size any shape sent to it by the amount indicated. The CSIZ value may be a positive or negative number. If a user does not enter ?-?when entering a value, then the CSIZ value will be converted to a positive number. Tracer Offsets: Right eye and left eye values, usually provided by the supplier, that determine the amount, in millimeters, to modify the dimensions of the trace. An OMA trace holds these values in the CSIZ record. Tracer offset values are required in order for a user to enter a tracer name; the values must be between -9.99 and +9.99. Trace: A file that contains specific data about the shape of a lens, including: A Box, B Box, Frame Type, Eye Size, tracing points, drilling points, and DBL. Tracer: A device that captures pertinent tracing data for lens processing by digitizing reference points per lens/frame for maximum precision.
