Blue Light

Blue light is a type of high-energy visible light that is part of the spectrum emitted naturally by the sun and artificially by digital screens like smartphones, computers, and LED lights. While it helps regulate our sleep-wake cycle and enhances alertness during the day, excessive exposure, especially in the evening, can cause eye strain, disrupt sleep patterns, and potentially contribute to digital eye strain. It's beneficial to use proper lighting, take regular breaks, and consider blue light filters or glasses to minimize adverse effects while still enjoying the benefits of modern technology.
