  • Blue light is a range of the visible light spectrum, defined as having a wavelength between 400−495 nm.
  • [1] This short wavelength means that blue light is a type of high-energy visible light, defined as having a wavelength between 400 and 450 nm. Violet, indigo, and some blue-green light are other types of high-energy visible light.
  • [2] Blue light, a type of high-energy light, is part of the visible light spectrum Blue light sources are becoming increasingly common in today’s environment. Exposure to blue light comes from a variety of technologies including computers, televisions, and lights.[1]
  • [3] Much of the exposure arises from light emitting diodes (LEDs). Today, many white LEDs are produced by pairing a blue LED with a lower-energy phosphor, thereby creating solid-state light (SSL).[3] This is often considered “the next generation of illumination”[3] as SSL technology dramatically reduces energy resource requirements. https://linkf.ly/Shawazah
  • [4] Increasingly, people are exposed to blue light via everyday technology. The 2015 Pew Research Center study found that 68% of U.S. adults own a smartphone and 45% own a tablet. The study also found that levels of technology ownership vary by age; 86% of Americans 18-29 and 83% of those 30-49 own smartphone.
  • [5] Younger Americans also use high rates of blue light technologies. The survey of Common Sense Media in 2013 also demonstrated that 72% of children age 0–8 years old used mobile devices for watching videos and playing games.
  • [6] Moreover, 93% of teens owned a computer or had access to one at home.
  • [7] In contrast, computer ownership rates are lower for older Americans.[5] Blue light exposure has been shown to impact health. Natural exposure to blue light during the daylight hours boosts people's energy, alertness and mood.
  • [8] However, elongated exposure to the waves transmitted through screen devices during the evening can disrupt circadian rhythm and cause various health effects including a disruption in normal sleep schedules.
  • [9] Scientists believe this is caused by blue-light-sensitive intrinsically photosensitive retinal ganglion cells suppressing the production of melatonin and/or stimulating the suprachiasmatic nucleus of the hypothalamus.[10]
