- Because of file naming conventions with the Comes calculator, the lab cannot set up the interface directly from the OE screen - the option "Interface at OE" is not available for Comes.
- Because Comes does not support the option to send labels with a value of "?", any labels that are not applicable for a particular job will not appear in the LDS file.
- For jobs with a frame trace, Rx-Universe will send CRIB=0 and ELLH=0 in the LDS file, which requests the Comes calculator to calculate optimal CRIB and ELLH values.
- Note that Comes does not calculate decentration on designs, so all designs in Rx-Universe should be set up with "Center design on frame" NOT checked.
- Comes does not support BRS requests, so the lab will need to set up base curve charts for the Comes designs. Chart 84 is available in Rx-Universe as a "standard" chart for digital lenses. When using this chart, the option ""Add add to sphere" should be checked, on the "Digital" tab of the design setup.
- The values returned for minimum and maximum edge thickness are not correct, so these should be treated with caution on Comes jobs.
- The Comes calculator does not check for curve out or thickness of the blank relative to the design. While Rx-Universe will check center thickness to confirm that a blank is thick enough in the center, it does not check the entire back surface against the blank, so it is possible a valid Comes calculation could result in an blank with insufficient thickness at some point(s). This could also be an issue with polarized lenses, since the Comes calculator is not verifying thickness against the location of the polarizing film.
- Decentration of Comes designs on uncuts is supported using labels BCERIN/BCERUP (beginning in version 7.24.00)
