Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
As our dependence on digital devices and artificial lighting increases, the complex pathways of the blue light spectrum that affect biological processes is crucial to understand. To reduce the hazards of blue light exposure, effective management strategies can be implemented, including limiting screen time before bed and using blue light filter.
[6] [4] Light seems to have therapeutic antidepressant effects when an organism is exposed to it at appropriate times during the circadian rhythm, regulating the sleep-wake cycle. [ 6 ] [ 4 ] In addition to mood, learning and memory become impaired when the circadian system shifts due to light stimuli, [ 6 ] [ 20 ] which can be seen in studies ...
As we've become more aware of how our screen-time habits may affect our sleep and even eye strain, some have sought out solutions to blocking something known as blue light.
Another popular claim is that blue light glasses can improve sleep. This is because blue light can suppress the body’s production of melatonin, the sleep hormone, but how much blue light affects ...
The researchers hope to conduct further research on the effects of blue light glasses on sleep, eye health, and more, Dr. Sumeer Singh, an author on the study from the Downie Laboratory, said in ...
A new review finds that the popular lenses don't help with eye strain, alertness or sleep. Do blue-light blocking glasses help prevent eye strain? A new review finds that the popular lenses don't ...
Providing white light and blue light has even greater impact for those with Alzheimer's disease (AD). So far, two lighting methods have been shown to improve nighttime sleep in AD patients: (1) exposure to bright white light (at least 2500 lx and as high as 8000 lx at the cornea) for at least one hour in the morning, for two weeks and (2 ...
