Third, the Camber designs use VCA labels to identify whether the lens is photochromatic, or polarized, and what color the lens is. If using an older implementation of IOT, it is possible these labels might not be in the list of labels sent to the calculator from Rx-Universe. This can be easily changed by modifying the LDI file for IOT to include PHOTO and POLAR. Please see the section on 1.1 Use of LDI (initialization files) with Digital Vendors for more information on this.
Lenticularization / Edge Blending
IOT has the option of allowing many designs to be "lenticularized", where the lab can specify a bowl size, in which the design is "true", and outside of the diameter, the lens is "blended" to minimize the thickness.
If the design has "_L" anywhere in the LNAM (on the digital tab), then the field "Blend Diam / Bowl Size" can be set on the F12 screen in order entry. 
In the above example, the progressive design would be cut into a 40mm bowl, and the lens outside of that 40mm bowl would be "blended" to minimize thickness in the finished product.
a fairly straight-forward interface, with a few things to note.
