Blue-light is generally defined as visible light ranging from 380nm to 500nm. Blue-light sometimes is further broken down into blue-violet light (roughly 380nm-450nm) and blue-turquoise light (roughly 450nm to 500nm). So approximately one-third of all visible light is considered high-energy visible (HEV) or "blue" light. Blue-light can cause dry eye syndrome, eye strain, insomnia, and can also damage your eye. It makes the brain perceive it as if it is daytime, and melatonin production is suppressed which may interfere with your sleep rhythms. KFILM blue-light rejection glass films protects your eyes by effectively blocking blue-light.
