OPERATING PROCEDURE: Accommodation Measurement

Press the graph

button to display the graph

display screen.

The detailed graph, accommodation

, maximum&minimum

AR-measured values, and maximum&minimum pupil size val-
ues are displayed.
The horizontal axis indicates the elapsed time in one-second
increments.

Press the graph

button to return to the accommodation measurement screen.

Switch the eye to be measured and measure the other eye in the same manner.

Graph display screen

*1. Accommodation increments is set by the “131. STEP” parameter independent from the display increments of the AR-measured

values.

• “ACC (accommodation)”, AR-measured “MIN (minimum value)”, “MAX (maximum value)”, pupil size

“MIN (minimum value)”, and “MAX (maximum value)” are printed out as measured results.

The greatest minus AR-measured value indicates “MAX (maximum value)”.

• To print the graph, set the “58. ACC GRAPH PRINT” parameter.
