Calculations of the five α-opic irradiances for all experimental conditions, following the SI-compliant approach recommended by the CIE.

Experimental condition	Cyanopic irradiance^a (μWcm⁻²)	Melanopic irradiance^a (μWcm⁻²)	Rhodopic irradiance^a (μWcm⁻²)	Chloropic irradiance^a (μWcm⁻²)	Erythropic irradiance^a (μWcm⁻²)
iPad with Blue Light Goggles	21.0	35.6	30.4	18.2	10.5
iPad Night Shift High CCT (5997 K)	6.0	7.7	9.6	11.1	11.5
iPad Night Shift Low CCT (2837 K)	1.3	3.8	5.9	9.3	12.1
iPad with Orange Goggles (control)	0	0	<0.1	<0.5	<1.0

CIE: International Commission on Illumination; CCT: correlated colour temperature.

Based upon the spectral irradiance distributions of the light sources, α-opic irradiances are calculated using the CIE’s SI-compliant version^20,21 of the Lucas et al.²² toolbox.
