Blue Light in Dermatology [PDF]
Life, 2021 Phototherapy is an important method of dermatological treatments. Ultraviolet (280–400 nm) therapy is of great importance; however, there are concerns of its long-term use, as it can lead to skin aging and carcinogenesis. This review aims to evaluate the

The Blue Light Hazard Versus Blue Light Hype
American Journal of Ophthalmology, 2022 The blue light hazard is the experimental finding that blue light is highly toxic to the retina (photic retinopathy), in brief abnormally intense exposures, including sungazing or vitreoretinal endoillumination. This term has been misused commercially to suggest, falsely, that ambient environmental light exposure causes phototoxicity to the retina ...

Daily blue-light exposure shortens lifespan and causes brain neurodegeneration in Drosophila
npj Aging and Mechanisms of Disease, 2019 Light is necessary for life, but prolonged exposure to artificial light is a matter of increasing health concern. Humans are exposed to increased amounts of light in the blue spectrum produced by light-emitting diodes (LEDs), which can interfere with ...

Blue light modulates the interactive effects of far-red light and day–night temperature difference on the growth, morphology and physiology of arugula and lettuce [PDF]
Frontiers in Plant ScienceIntroductionFar-red (FR; 700–800 nm) light and the difference between day and night temperature (DIF) interactively regulate plant morphology and growth. FR light and +DIF synergistically promote stem elongation, often reducing leaf expansion and overall
