If you see a blue screen, the vision screener is either too close or too far from
the subject. The vision screener also displays a prompt. Move forward or
backward as needed.
If the subject's pupils are too small, the vision screener displays a message to
adjust the lighting in the room. A darker environment promotes larger pupil size.
If the device is taking a long time to start screening, make sure you can see the
subject's eyes on the screen and that the vision screener is on a level with the
subject's eyes.
Avoid pointing the vision screener too high, which encourages the subject to
look upward.
Retry the screening.
Flag the record.
Try using monocular mode.
