The Blue Light Hazard Versus Blue Light Hype
American Journal of Ophthalmology, 2022The 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 ...

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.

Scientific American, 2016
The article discusses the effects of blue light from electronic devices on people's ability to sleep. Topics discussed include the claim that blue light from the screens of computers and smartphones suppresses the hormone that induces sleepiness called melatonin, the solutions developed to help people sleep, such as tinted eyeglasses and natural ...

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.

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.,

Planta, 2004
In the past decade, three groups of blue-light photore ceptor have been identified in higher plants, namely, cryptochromes, photo tropins, and the ZTL/FKF1/ LKP2 family. All of them contain flavins as the chro mophore. In addition, opsin-related photoreceptors were found in Volvox and Chlamydomonas, and FAD containing photoactivated adenylyl cyclases ...

Trends in Plant Science, 2000
Plants have several blue-light receptors, which regulate different aspects of growth and development. Recent studies have identified three such receptors: cryptochrome 1, cryptochrome 2 and phototropin. Cryptochromes 1 and 2 are photolyase-like receptors that regulate hypocotyl growth and flowering time; phototropin mediates phototropism in response to
