Mostly work but not ideal for precision viewing
I've only tried using these glasses for blocking out visible UV light (yeah, I know that sounds like an oxymoron, but the really longwave UV that LED's emit is quite visible), and they're not ideal. For one, they don't block it out entirely; I can still see it coming from the LED's through them. Worse yet, they are actually slightly fluorescent, so when they are blocking UV, they also cast a noticeable orange glow over everything you look at. My goal was picking up on mildly fluorescing materials from a distance in total darkness, so I needed something that would eliminate all visible glow from the lamp. Needless to say these did not cut it. Thing is, I had previously bought very similar-looking (and similarly priced) UV safety glasses from Amazon that did exactly that, cut out all UV with no fluorescence, so it's not like this is asking for too much. Sadly, they were also some nondescript brand like these ones an I've lost track of them.<br /><br />Honestly, these are fine for most of what people would need them for, but there's better out there
