Setting-Up Tests 3-23
Inserting Trial Lenses Into the Holder
1
Move the trial lens holder into an upright position from its storage
position in the bottom of the bowl.
2
Place the cylinder lens in the slot farthest away from the patient
and align the axis.
3
Place the sphere lens in the slot closest to the patient (in front of
the cylinder lens).
Note: Use only the narrow rimmed type of trial lenses. The wide-rimmed variety will interfere with
the patient’s peripheral vision and adversely affect test results. It is helpful to move the lens handle
towards the patient’s temporal side so it does not interfere with the patient’s eye brow or nose.
