Blue, high-energy visible light is a much-discussed topic. We've covered a lot of interesting facts and information in the featured story about blue light and its effects on our eyes, our visual comfort, and our sleep rhythm, as well as some of its positive effects. The following article covers an additional list of frequently asked questions about blue light.
FAQ1: What influence does blue, high-energy light have on eye health, vision, and well-being?
- Are computer screens really bad for eye health?
- Can the use of a smartphone disrupt sleep cycles?
- Do lenses that filter or reduce blue light help?
Basically, it comes down to the fact that blue, high-energy light and its effects on eye health and well-being remains a topic that is subject to more in-depth research.
The blue light spectrum borders directly on the ultra-violet range, which has long been established as a health hazard with detrimental effects on biological cells. But the current state of scientific and clinical research suggests that there is no acute risk of retinal damage caused by interior lighting of any kind or by the daily use of mobile devices such as smartphones and tablet PCs. The intensities of artificial blue light from LEDs and screens are far below any currently defined thresholds related to blue light hazards.
Nevertheless, blue light can have an impact on our visual comfort, wellbeing, and our wake-sleep cycle. Read more about that in the main article “Blue Light and Vision”.
FAQ 2: Does more blue light in the home office cause damage to the eyes?
FAQ3: Do eyeglass lenses need to offer protection against blue light?
FAQ 4: Should gamers or people who work with computers for long hours wear special blue filter glasses?
FAQ5: The brightness of a smartphone screen can be dimmed (night shift). Are these setting options helpful?
There are many apps and setting options available for smartphones and screens that are specifically designed to reduce the relative amount of blue light emitted. Despite the scientific evidence, it is reasonable and recommended to dim the light intensity of screens and adjust the overall brightness and color temperature to increase visual comfort and improve overall well-being.
