Tianjin42 Posted January 5, 2016 at 01:47 PM Report Share Posted January 5, 2016 at 01:47 PM A Chinese friend yesterday mentioned that the glasses she wears are not to correct vision. They are actually anti-radiation glasses (防辐射眼镜). She explained that they "stop the radiation from the computer screen and TV going into my eyes". Previously on this forum we have discussed the anti-radiation clothing for pregnant women that is, I would argue, something of a scam. But this is the first time I have encountered these glasses. They seem like plastic to me and were bought for about 100 CNY and the plastic is clear rather than shaded. Apparently they are becoming ever more popular. Anyone seen these before or know anything concrete about their efficacy? Despite screens emitting radiation, I am doubtful about what this really offers.

li3wei1 Posted January 5, 2016 at 01:53 PM Report Share Posted January 5, 2016 at 01:53 PM radiation may be a mistranslation of something, or rather it is technically radiation, but electromagnetic rather than nuclear. When I bought reading glasses from a respected UK firm, I paid extra for something similar that is supposed to block harmful something-or-other from computer screens. Harmful only to the eyes, and not too harmful, as I've been staring at the screen for the last few decades, off and on, and I don't wear the glasses all the time now I have them, but I thought, why not?

Tianjin42 Posted January 5, 2016 at 02:09 PM Author Report Share Posted January 5, 2016 at 02:09 PM Interesting - thanks for that. I'm not a scientist (and don't wear glasses) - happy to learn from someone who knows a little more about the topic. Quote Link to comment Share on other sites More sharing options...
Shelley Posted January 5, 2016 at 02:18 PM Report Share Posted January 5, 2016 at 02:18 PM CRT - Cathode Ray tubes do emit a very low, harmless level of x-rays. LCD and LED TVs and monitors do not. This is one of those things New Scientist happily calls fruitloopery So ditch the glasses and enjoy. What the opticians put on your lenses is anti-glare to help with looking at screen. 3 Quote Link to comment Share on other sites More sharing options...
dandmcd Posted January 6, 2016 at 06:29 AM Report Share Posted January 6, 2016 at 06:29 AM Absolutely a scam. Same with anti-radiation clothing, and also wifi routers that give off more "safe" radiation signals. All scams to to get scared new mothers and their grandparents that never received an education to buy their products out of fear. Quote Link to comment Share on other sites More sharing options...
dwq Posted January 8, 2016 at 09:55 PM Report Share Posted January 8, 2016 at 09:55 PM Probably those are "Blue light blocking" glasses. The claim is blue light has higher energy and too much of it can damage your retina, blah blah blah. http://www.beoptic.com/knowledge-2013-0513/ Some now says that those glasses can lower percieved brightness and make your eyes work harder, not good. http://hk.apple.nextmedia.com/news/art/20140918/18870185 Quote Link to comment Share on other sites More sharing options...
