Blue Light Protection, Part I—Effects of blue light on the skin
Journal of Cosmetic Dermatology, 2020Abstract–Part IBackgroundBlue light is emitted visible light between the wavelengths of 400 to 500 nm. The main source of blue light is sunlight, but digital screens, light‐emitting diodes (LEDs), and fluorescent lighting serve as additional sources. Concerns about the negative effects of blue light on the skin have rapidly increased over the past 15 ...

Proceedings of the ACM on Computer Graphics and Interactive Techniques, 2022
We introduce virtual blue noise lighting, a rendering pipeline for estimating indirect illumination with a blue noise distribution of virtual lights. Our pipeline is designed for virtual lights with non-uniform emission profiles that are more expensive to store, but required for properly and efficiently handling specular transport. Unlike the

Although blue light has been present in our lives for decades, this type of visible light has recently become a topic of significant interest as we shift to a greater percentage of our time spent in front of light-emitting devices. Especially during the Covid pandemic, as many companies pivoted from in-person meetings to discussions conducted via video

The Laryngoscope, 1975
AbstractThe introduction of high intensity proximal light sources has greatly improved the already high standard in technique of endoscopy. They enable us to illuminate the periphery of the bronchi. The advantage of better illumination must, nevertheless, be paid for with a levelling of contrast, as the bright light outshines the fine differences (e.g.,

Science, 1998
Plants can sense day length and use this information to trigger flowering. As described in a research commentary by SuAirez-LA³pez and Coupland, work published in this issue ( Guo et al.) describes a new photoperiod receptor, one that detects blue light, in the plant Arabidopsis.

Vision Research, 1990
Rats have been extensively used in light damage studies. Retinal damage threshold for white light were found at 1-10 J/cm2, and the action spectrum resembled the absorption spectrum of visual pigment. We wished to answer the question whether a different class of light damage, the "blue light hazard", with white light damage thresholds at about 300 J ...

Aureochromes – Blue Light Receptors
Biochemistry (Moscow), 2018A variety of living organisms including bacteria, fungi, animals, and plants use blue light (BL) to adapt to changing ambient light. Photosynthetic forms (plants and algae) require energy of light for photosynthesis, movements, development, and regulation of activity.

Cryptogam blue-light photoreceptors
Current Opinion in Plant Biology, 2003Blue light regulates various aspects of plant development. Extensive research using Arabidopsis thaliana has advanced our understanding of blue-light photoreceptors and signal transduction pathways in flowering plants, but our knowledge of blue-light signaling in other plant systems, particularly in cryptogams (i.e.

Blue Light Perception in Bacteria
Photosynthesis Research, 2004This review focuses on the blue light responses in bacteria and on the bacterial proteins which have been demonstrated to function as blue light receptors. Results of the previous years reveal that different types of photoreceptors have already evolved in prokaryotes.
