Light in general is made up of particles that travel in waves that emit energy. These particles vary in length and intensity.
Blue lights are a type of high-energy light that emits a blue tone. They come from various sources, including electronic devices such as mobile phones, tablets, computers and televisions, as well as LED lighting used in homes, offices and public spaces. Unlike natural blue lights, such as sunlight, which contain a wide range of colors, artificial blue lights emit a specific wavelength that can have shocking effects on our eyes and visual health.
