During a Diagnostic
After you select to begin the measurement procedure, the Measure screen shows
information about the procedure's progress. When both eyes are being measured, the
diagnostic is performed simultaneously for both, although the processing of one eye may take
longer than that of the other eye. A progress bar below the image of each eye shows the
current stage of that eye.
During the first stage of the diagnostic, the system attempts to center the patient's eyes in the
camera views. When it detects one of the patient's eyes in the camera view, it superimposes a
circle on it, and then adjusts the height of the head so that the center of the eye is as close as
possible to the center of the camera view. When the middle of the patient's eye is aligned well
enough with the center of the camera view for the diagnostic to be performed, the circle
identifying the eye is green; when the eye is not centered well enough, the circle is red.
Throughout the measurement process, if the system is having trouble locating the centers of
the patient's eyes, you can help it in the Measure screen, by adjusting the unit's heads and
chin rest, and by tapping the patient's eyes in the camera views.
When the diagnostic is underway, you can skip stages of the test, or stop the test entirely, from
the Measure screen. You cannot, however, activate or deactivate one of the eyes during a
diagnostic.
