The standard Crossbows prices offer discount when lens production passes a threshold.  Crossbows pricing will start on the most expensive price per lens and as the threshold is passed the software will recalculate the price for all the progressive lenses calculated for that month on the cheaper rate and provide a credit for the difference.

The CrossbowsRX™ software requires an internet connection every 2 days in order to function.  However, a constant internet connection will allow the customer to avail of several useful features including our web portal, low click warnings and automatic backup of critical settings.

The Crossbows dongle will check the time and date every two days and if there is no internet connection then this error will appear.  Once internet is restored open the CodeMeter Control Center and select ‘Process – Update Time Certificates’ to resolve this issue.

Crossbows will charge for every calculation unless told otherwise.  There are several options available depending on the Lab Management System (LMS) used.
