ProFit

ProFit is a very basic digital calculator – there is no support for BRS requests, so the lab will need to set up base curve charts according to their preferences for each material to be used.

The following designs are available from ProFit (as of Jan 2013):

Note that ProFit uses a combination of LNAM, LDNAM and CORRLEN to identify the design. 

CORRLEN can be specified as an optional VCA label on the lens style.  For example, the Identity Indoor 16 design would be set up as follows (note the setting of both LNAM and LDNAM):

The LDTYPE entry may or may not be required, but specifying it ensures compatibility when using other LDS systems that may not use SDF files.

Note that ProFit’s near vision design (Office+) expects the Rx to be entered as NEAR power in the Rx, and the degression is entered where the ADD power would normally be entered.  This is different than all other near vision LDS designs we have interfaced with to date. 

For the IOFF, which is a near vision digital design, you also need to set LTYP to DG – since DG is not currently one of the recognized VC values for the label, this needs to be set up in the optional labels of the lens style:
