The monitor may be viewed directly or via a mirror.

Direct viewing

Place the monitor at or slightly above the patient‘s eye level. The program can be configured for any viewing distance but in practice viewing distances of less than 3 metres are not advised because:

• The smaller letter sizes will not be reproduced well on the monitor
• Some refractive compensation for viewing distance may become necessary

Viewing via a mirror






To maximize the screen viewing distance within the consulting room, most practitioners prefer to have the patient view the test chart via a mirror.

Mount the monitor on a shelf or bracket above the patient's head. Ensure the mirror is correctly positioned so that the monitor is seen in the centre of the mirror.

Select Mirror optotypes from the Setup screen to mirror the optotypes.

• A separate power supply (not incorporated into the base unit
