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.
Exposure to blue light at night can suppress the body's natural production of melatonin, making it difficult to sleep. ... "Age-related macular degeneration is caused by a gradual deterioration of ...
The blue light spectrum is an essential part of the visible spectrum with wavelengths of about 400-480 nm. [1] Blue light is primarily generated by Light-Emitting Diodes (LED) lighting and digital screens, it has now become prevalent in the world around us. [2] LED lighting creates white light by combining blue light with other wavelengths ...
Macular degeneration, also known as age-related macular degeneration (AMD or ARMD), is a medical condition which may result in blurred or no vision in the center of the visual field.
