This is incorrect. Eyes absorb light and produce electrical signals interpreted as vision by the brain. Further, it seems to me that the set of thing that ‘the light of the body’ describes is an empty set; there’s no literal interpretation (our bodies do not shed visible light) and there’s no construction similar enough that suggests an interpretation (the X of the body / the light of the X). “The light of the sun” / “The light of the moon” is the closest I can find and both of those suggest the literal interpretation.
Our body does scatter visible light, though, much like the moon does.
