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:
Type 3 – Editor Utilities and press enter.
Type 6 – Configuration Editor and press enter.
Type 5 – Edit Special Lens Types and press enter.
The Special Lens Type Edit screen displays.
- Type the applicable Special Lens Type code and press enter.
The following fields will display.
- 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 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 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. A review of potential progressives that are NEVER prism thinned is appropriate 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.
