Figure 6.

Logistic plot comparing the measured 1-h response data from the present experiment with the predicted responses from the original CS model to validate its accuracy. The data points correspond to mean nocturnal melatonin suppression following 1-h exposures to the 2700 K and the 6500 K sources at different corneal light levels (CL_A, Equation 1). The continuous solid line represents the respective predicted CS values according to Equation 2 and depicts the functional relationship between CL_A and CS plotted without regard for the measured melatonin suppression values obtained in the present study. Goodness of fit (R²) for the logistic function is 0.90. The error bars represent SEM.
