What is Blue Light
Blue light is a range of the visible light spectrum coming from a variety of technologies including computers, smartphones, televisions, and lights.
Natural exposure to blue light during the daylight hours boosts people's energy, alertness and mood. However, elongated exposure to the waves transmitted through screen devices during the evening in lowlight circumstance can disrupt circadian rhythm and cause various health effects including a disruption in normal sleep schedules.
Thus, blue light should be decreased at night.
