Essilor

Essilor

For many designs, Essilor offers the design in regular and short.  The LMS is responsible for switching to the short design if the seg height of the order is < X (usually 18mm), and the add power is <= 3.00D.  (If the add is > 3.00, the regular design is used regardless of the seg height).

To accomplish this, even though OMICS does not select blanks, the alias file is used to trigger switching between regular and short designs.  For example, to set up an alias from Physio Enhanced Azio to Physio Enhanced Azio Short, the lens styles would be set up similar to:

Regular design set up with minimum seg height of 18mm, and maximum add of 3.50

 
Short design set up with minimum seg height of 14, maximum add power of 3.00

Both styles are set up with the option “LDS selects blanks to use” checked on the Optional tab.

Then set up an alias record from PHEAZ to PHEAZS.

When design PHEAZ is used on an order, OMICS will check the alias file, and will switch to the PHEAZS design if the seg height of the order is < than the minimum specified for the requested design, and if the add power is less than the maximum add power specified on the alias lens style.  Multiple alias records can be specified, to allow checking multiple lens styles (ie several corridor lengths).

Varilux S

Varilux S processing adds some additional complexity to the digital interface.  Additional steps in the blocking and verification process require the files received back from Essilor to be saved somewhat differently.

On the Digital Type screen, for Essilor only, is a box titled "Extended Paths".  When clicked, a new box is presenting that allows paths to be specified for the files that will be created for different devices, based on the information returned from Essilor:

In the above example, the section of code in the LMS file identified as "CTA", for example, would be saved as file(s) in the ESSILOR\CTA folder.
