Blue light is a type of high-energy visible (HEV) light that is emitted by digital devices such as smartphones, tablets, and computer screens. While this technology has revolutionized the way we live and work, prolonged exposure to blue light can have negative effects on our health. Studies have shown that blue light can disrupt our sleep cycle, cause eye strain and fatigue, and even contribute to the development of age-related macular degeneration (AMD). However, there are ways to mitigate the negative effects of blue light, such as wearing blue light blocking glasses or reducing screen time before bed. By being aware of the potential risks and taking steps to protect ourselves, we can continue to enjoy the benefits of technology while safeguarding our health.
