[A new sieve-test for testing colour vision (author's transl)].
From our results we can be sure that the colour test disk is at least as reliable for mass testing for colour blindness as the Ishihara isochromatic colour plates. In practice the test disk has the advantage of constancy of testing conditions and easy and quick procedure. If it is necessary to differentiate between protopia and deuteropia the colour test disk is significantly better Ishihara's colour plates.
