This test measures the number of degrees of clock-wise or counter-clockwise cyclotorsion of the two eyes compared to each other. This is not a test of absolution torsion of one eye. Therefore, it does not matter if the card is slightly tilted while testing. If the test result shows cyclotorsion, then the Bernell Torsion Training Cards may be used.
