For quite a while, I've been using privacy screens, which not only increase... well, privacy, but also purportedly block blue light. However, web search results generally yield very broad statements about this effect. So, can someone answer these inquiries I have?
- Which types of privacy screens (i.e., what materials) would be best at blocking blue light?
- Many glasses already offer blue light protection—in any case, how well does the protection from the privacy screen compound with this? In other words, does the 'blue-light blocking' feature of privacy screens really make a difference if other objects like glasses lenses already provide the same function?
