Within Acuity Logic, AEG does not utilize GP materials as selectable Lens Styles. This is because GP materials are used across multiple lens designs, each of which may correspond to different billing codes.
To ensure accurate pricing and insurance coding, AEG standardizes ordering through Lens Styles rather than material selection.
In cases where the final lens design has not yet been determined and consultation is required; AEG has created placeholder options labeled:
“Custom ___ (GP Design)” under each specialty vendor.

When selecting one of these options, staff should also choose the appropriate Modality (Sphere, Toric, or Multifocal) within Acuity Logic. This approach ensures:
- Proper alignment with billing and insurance requirements
- Accurate pricing at the time of order
- Flexibility during the consultation and design process
