Trial lenses can be added by clicking the 'New Trial Lens' button at the top of the window. This will bring up the lens wizard once again, where you can select the appropriate lenses for the patient.

Once lenses have been selected, they will appear in their own tab, similar to the dispense screen. You can add more than one pair of trial lenses here. You may have to manually select the BOZR if multiple base curves are available for that lens. You can then choose the BVP, where only powers available for that lens are shown. For Toric lenses you can add in the Cyl / Axis and Add.

Within this tab, you can also change the status of the lenses if needed, add any advice given to the patient about the trial lenses and also set up staff tasks to be created.
