Sure, we know that ultraviolet light has its risks to humans, both for skin and for eyes, but purportedly even strong blue light can be risky too. How? It can more readily cause irreversible changes in the retina that can lead to permanent damage. The risks to humans in domestic uses such as LED lighting currently seem relatively low, and in general, this is much more of a risk factor when blue light is abused or when people are otherwise overexposed in factory environments, for example.
