Okay, don't all come running at me with pitch forks and torches, and fitting me for a tinfoil hat. Please hear me out for just a moment. There have been questions in other threads regarding whether FaceID, which works by projecting an array of infrared dots over your face, including your eyes, can in any way have negative long term effects. Most people have been dismissive of such concerns, and perhaps rightfully so. But I figured there's no harm in having a dedicated thread where we can look see what scientific information is out there. I've come across a few papers so far: https://academic.oup.com/annweh/article-abstract/35/1/1/170395 This paper is about workers who are exposed to much stronger IR radiation that what FaceID would possibly emit (emitted from heat sources like molten steel). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3116568/ This one looks at the effects of less intense sources. https://saunaspace.com/wp-content/uploads/2015/03/Radiation-effects-on-the-eye.pdf This article seems to also suggest that more intense sources are needed to cause harm.
