Cross Cylinder Test with Dots Chart (CYL)
The 3rd step of the System-Defined Program is to revise the value of CYL
for the right eye more elaborately, based on the result of 1st step SPH-
CYL-AXIS test. In case of Jackson Cross Cylinder Test, ask the patient with
which eye he looks more clearly, while pressing number [1] and [2]
buttons alternately. When he says number [1], turn the dial in + direction
(counterclockwise), while number [2] in – direction (clockwise.) Continue
this until the patient answers that he sees both with similar clarity.
