(6) Eyeball Diagram representing refraction power
It is possible to print the refraction state diagram regarding the result of the REF measurement
to the internal printer. This function will be performed when ‘
PRINT=EYE : ON
’ in the Page 3/4
of the SETUP MODE. See the following table and diagram for further information.
