In this example the patient is looking to the left of the camera (from the patient’s
perspective). The red dots in the gaze chart illustrate this line of vision.
b) Patient does not focus on camera!
Cause:
This error message is displayed if the patient is not looking at the hexagonal nose
in the camera face.
Reason:
To prevent incorrect refraction measurements in the periphery of the eye, both
eyes must be directed at the center of the camera.
Tip:
Position the child so that knees and nose are in line with the camera. Do not use
any external fixation aids and remain calm. Both corneal reflexes must be located
in the center of the pupils in measurement result page, neither of the two gaze
charts may show red dots, but only green dots.
