Comparison between irradiance levels integrated over 10 nm-wide light bands (designated by their central wavelengths) on isolated cones, their correspondence at the corneal level for the different wavelengths and measured outdoor irradiances in Paris on a sunny morning (11:00 am) on August 29th, 2017, East orientation, 5th floor of a building, light sensor oriented at −15° downward.
