It is worth noting that the American Medical Association (AMA) is not indicating any direct effects from the blue light. The postulated harm is from indirect effects. There are two concerns. First, the spectrum of light could increase glare and reduce visual acuity. Second, the additional blue light could affect the sleep cycles of people exposed to the light, leaving them less able to get enough rest.
It’s also interesting to me that the article cites research into the effects of brighter nighttime street lighting, but not necessarily LED street lighting. Personally, I would prefer to see clear research linking LED lighting to the proposed problems before recommending changes. This research may exist and the lack of references may just be the fault of the person who wrote the short article.
