Ah, not getting from context that it was meant to be melanin is a worse error than mistaking melatonin for melanin, lol.I think his point was the term should have been melanin. UV without melanin leads to sunburn.Melatonin is partially regulated from signal from the melanopsin receptors in the periphery of the retina that are impacted from blue and green light only - UV won't get in - too busy making cataracts...
The melanopsin receptors send signals to the circadian rhythm center, etc...
