Table 1.
Comparison of results for left and right eyes.
Fig 1.
(a). A graphical presentation of the Rayleigh test parameters. Mean values of R1, R2, RC and Rw parameters in the Rayleigh test are presented. Y1—the maximum brightness of yellow, Y2—the minimum brightness of yellow. (b) A graphical presentation of the Moreland test parameters. Mean values of M1, M2, MC and Mw parameters in the Moreland test are shown. C1—the minimum brightness of cyan, C2—the maximum brightness of cyan.
Table 2.
Mean and median values obtained for all study subjects expressed in anomaloscope units, presented separately for males and females.
Fig 2.
Distribution of a) R1, R2 and RC; b) M1, M2 and MC; R1 –the lower limit of the matching range for the Rayleigh test, R2 –the upper limit of the matching range for the Rayleigh test, RC−central matching for the Rayleigh test, M1 –the lower limit of the matching range for the Moreland test, M2 –the upper limit of the matching range for the Moreland test, MC−central matching for the Moreland test; N–the number of eyes.
Fig 3.
Distribution of R2 for the Rayleigh test.
(a) Notice the two peaks: approximately at 47 and around the value of 52. (b) The distribution of R2 in the Rayleigh test is presented separately for female and male subjects.
