The human eye can see the light frequency spectrum falls on the visible light scope (approximately the 400~700nm wave length), the eye can the sensation color mainly rely on awl cell (cones), drills the cell content bluish green red three kinds to regard the light corpuscle. Why looked that the green energy of light protects eye's reason to lie in the green light the wave length simultaneously to fall in the bluish green red three kinds regards the light corpuscle absorption spectrum the wave ridge lower limb (i.e. three kinds sum total irritability which regards light corpuscle to receive to be few), therefore also achieves “the rest” effect.
