2) Example of the primary and secondary addition powers in the right data (ADD = +2.00 D, ADD2
= +2.50 D
3) Example of the primary and secondary addition powers represented by spherical powers in the
left data
(ADD = +2.00 D, ADD2 = +2.50 D)
(NSPH = -1.00 D, NSPH2 = -0.50 D)
(8)PRISM data
The measurement data of the prism power is output.
When the “PrismTx” parameter is set to “On”, the prism data is output in the format of “BU/D
BI/O” setting.
When the PrismTx parameter is set to “Display”, the form varies with the prism representa-
tion mode.
When the Prism parameter is set to BU/D BI/O:
The measurement data is output as fixed four digits including a decimal point with no
polarity sign and the leading digit 0 remaining.
In addition, a character representing the base direction is added to the end of the mea-
surement data.
E.g.) IN 3.00, UP 2.50: 03.00 I 02.50 U
OUT 1.25, DOWN 2.00: 01.25 O 02.00 D
