What is blue light?

Blue light is a part of the visible light spectrum, which ranges from about 380 to 500 nanometers (nm). It has a shorter wavelength and higher energy compared to other colors in the visible spectrum. Blue light is emitted naturally by the sun and artificially by digital screens (like smartphones, tablets, and computers), LED lights, and fluorescent lighting.

Key Points about Blue Light:
Wavelength: Blue light falls within the 380-500 nm range.
Energy: It has higher energy due to its shorter wavelength.
Sources: The sun (natural source), digital screens, LED lights, and fluorescent lights (artificial sources).

Impact on Health:

Circadian Rhythm: Blue light exposure, especially in the evening, can disrupt sleep by interfering with the body's production of melatonin, a hormone that regulates sleep.
Eye Strain:
1.Prolonged exposure to blue light from screens can cause digital eye strain, leading to discomfort and fatigue.
2.Stronger than UV! Blue light damages the retina and causes macular bleeding.
3.Retinal macular degeneration caused by blue light has become the number one killer of human vision.
4.The World Health Organization reports that blue light is the leading cause of poor vision, and macular degeneration has surpassed the previous ranking
Cataracts.
