Cross Cylinder - Split Cyl Test
The Split Cyl Cross Cylinder test allows the patient to see two test charts at the same time when
adjusting Axis and Cylinder, making it easier for the patient to compare different Axis positions and
Cylinder power values. (Please refer to Figure IU-21.)
The Split Cyl lens has red and green markings on each half of the lens. The patient indicates to the
examiner which test chart appears clearer, by stating whether the chart corresponding to the red or
green side of the lens appears clearer.
1. Touch XCyl on the menu bar at the bottom of the main screen.
2. Touch Split Cyl to start the test.
3. Touch Test to switch the type of XCyl test (Manual/Smart/Split Cyl).
