A recently published (17 Oct 2019) study[1] in Nature Journal - Aging and Mechanisms of Disease, titled Daily blue-light exposure shortens lifespan and causes brain neurodegeneration in Drosophila sought to study the long term effects of daily artificial blue light exposure typical of LED lights and screens. This research has uncovered some alarming effects well beyond the already known cellular eye damage.
With increasing agreement among researchers that the circadian system is a major regulator of almost every aspect of human health and metabolism, the case is now being put forward that Metabolic Syndrome be renamed Circadian Syndrome in this paper just published in the Journal of Internal Medicine.
In the published study, Blue light effect on retinal pigment epithelial cells by display devices it shows specifically how the backlighting from display screens of devices induce cell death in the eyes.  They found that even “white light”, made up of blue, red and green as produced by illuminated display devices also triggered the production of Reactive Oxygen Species (ROS) in the mitochondria
Blue light is linked to Aged Macular Degeneration, and now AMD is linked to Alzheimers.  A study of 3,877 randomly selected patients found a significant link between three degenerative eye diseases – age-related macular degeneration, diabetic retinopathy and glaucoma – and Alzheimer’ disease. Over the five-year study, 792 cases of Alzheimer’s disease were diagnosed by a committee of dementia experts. Patients with age-related macular degeneration, diabetic retinopathy, or glaucoma were at 40 % to 50% greater risk of developing Alzheimer’s disease compared to similar people without these eye conditions.
