Blue Light

Blue light refers to a range of high-energy visible (HEV) light with a wavelength of around 400-450 nanometers, emitted by digital devices such as smartphones, computers, and televisions. As people increasingly spend time in front of screens, concerns about the potential impact of blue light on eye health and sleep patterns have grown, making it a topic of interest in the tech community, with many developers and users seeking ways to mitigate its effects through software and hardware solutions.
