The reason blue lights dazzle more is that the shorter wavelength blue 
light is scattered more by passage thru air, .... that's why the sky is 
blue at midday, being filtered and scattered by the earth's atmosphere, 
and orange at sunset since all the blue has been completely scattered 
and absorbed by it's longer/oblique passage thru the atmosphere.
