Blaufiltern

Blaufiltern is a term used to describe the process of reducing or blocking blue light emitted from digital screens. Blue light is a part of the visible light spectrum that can be seen by the human eye. While natural blue light from the sun helps regulate our sleep-wake cycle, excessive exposure to artificial blue light from devices like smartphones, tablets, and computers, especially in the evening, can potentially interfere with melatonin production. Melatonin is a hormone that plays a crucial role in sleep.

Devices often have built-in features that allow users to adjust screen color temperature, shifting it towards warmer tones, which in effect reduces blue light emission. This is sometimes referred to as "night mode" or "blue light filter." Additionally, specialized screen protectors and eyewear are available that claim to filter out a percentage of blue light. The primary motivation for using blaufiltern is often to alleviate potential eye strain and improve sleep quality for individuals who spend significant time using digital devices. Research into the long-term effects of blue light exposure and the efficacy of various filtering methods is ongoing.
