Introduction
This document provides instructions for editing the Special Lens Types table. The Special Lens Types table contains additional data for Surface Blocking and Prism Thinning setups for both aspheric and progressive lens designs. The two fields that need review or modification are 1) Blocking and 2) Prism Thin.
Procedure
From the Optifacts main menu:
Select Option 3 – Editor Utilities and press Enter.
Select Option 6 – Configuration Editor and press Enter.
Select Option 5 – Edit Special Lens Select Options and press Enter.
The Special Lens Type Edit screen displays.
- Enter the applicable Special Lens Type code.
The following screen is displayed.
- Set the following fields as applicable.
| Field Name | Definition |
|---|---|
Blocking | For default blocking: M=MRP, C=On Cneter, S=System configuration entry Choices are “M” for MRP (OC blocking), “C” for On-Center (Geometric) blocking, and “S” for the use of the setting in Lab Material Configuration table. Setting this field to “S” keeps the lens on the default setting from the Lab Material Configuration (Center Blk field). If the lab does NOT want to block on the geometric center, then set the appropriate progressives to “M.” |
Prism Thin | Enter A to Always, N to Never, S to let System decide prism thinning Choices are “A” for always prism thin regardless of Account Material Configuration settings, “N” to never prism thin this lens type, and “S” to use the parameters set in the Account Material Configuration table. We recommend a review of potential progressives that are NEVER prism thinned with the lab manager. An example of a lens that generally is not prism thinned is the AO Omni Progressive – which has built-in prism thinning. |
- Press Escape to exit.
