You can alter the first eye tested in this screen by selecting the OD (RIGHT) or OS (LEFT)
buttons above the chart.
In the Testing Screen, the video eye monitoring will display a live image of the patient’s eye to aid
in proper alignment of the patient and to ensure fixation during testing. Selecting the
Freeze
Button will freeze the live image of the eye. This provides the capability to measure the pupil size
using the increments on the cross hair in the frozen video image. The markings on the cross hair
are in 1mm increments. Press the
Unfreeze
Button to return to live video.
