Blue light is a term commonly associated with the harmful rays emitted from electronic gadgets, especially smartphones and laptops. Synonyms for blue light are numerous and include computer light, digital light, screen light, and electronic light. Other synonyms include high-energy visible (HEV) light, blue-violet light, and blue-light-emitting diodes (LEDs). These synonyms highlight the fact that blue light is emitted not only from electronic gadgets but also from energy-efficient LED lights used in homes and workplaces. The long-term impact of blue light exposure is still unclear, but it is known to disrupt sleep patterns, cause eye strain and headaches, and even lead to macular degeneration. It is therefore essential to reduce exposure to blue light, especially during nighttime.
