Blue Light

Blue light

Blue light is a type of light with a short wavelength and high energy that is found in sunlight and many artificial sources, such as electronic devices like smartphones, tablets, and computers. Exposure to blue light has been linked to a variety of health concerns, including disrupted sleep patterns, eye strain, and increased risk of macular degeneration. Some people use blue light filters or glasses that block or reduce the amount of blue light they are exposed to in order to reduce these risks. Additionally, some studies have suggested that exposure to blue light in the morning can help regulate the body's circadian rhythm and improve alertness and cognitive function.
