Not sure about nitrogen filled. They are made in Japan for sure. We own two and both are flawless, never any fogging.

Hey, I have no clue. All I know is this is the 2nd pair of the same binocs I've bought. I like them a lot and think I got a good value for my money (twice).

I do not know the answer to your question but I do know that they are excellent binoculars, clear, precise and light, an excellent value for what you get.

Hi Sam, I owned the 58mm set of these filters and was not happy with them. They are listed as "Japan Optics" but are actually made in China. The warming filter is plastic, not glass. The CP has a minimal polarizing effect at best. And, from what I can tell compared to my Hoya filters, these are definitely not coated optics. I sent mine back yesterday. YMMV. Cheers, SB

I personaly have no clue but my guess is that the uv comes baked into the lense and the flaking part is the anti fog coating. But thats just my guess. Either way i dont realy use those for anything realy off road or intense because I get a bit of a gap in the nose section of the goggles.

The best i can tell they are in fact made by HID. The ones i have bought have HID stamped on them and they work as well with my card readers as the ones my security company charges almost twice this amount for. I have about 150 of these i service now.

Mine have not fogged during the six months + that I have been using them. All of my shooting during that time has been done at a well ventilated indoor range. I have no experience with them outdoors or in extreme conditions.

Mine say Masons. I don't know if they are made by Ball or not. Mine also have a greenish tint to them. Not completely clear, but I do like them.

The binoculars don't say anything about gas on them. When I was researching which glasses to buy, I never saw anything about gas on any I looked at and I don't remember the manual saying anything about gas. I don't know for sure, but I don't believe there is gas in them.

Hi, Unless the mugs have changed since I ordered in 2013 they are clear glass with no hint of a green tint.

I have seen some rumblings online that they are made in China, but I thought they were made in Israel. What I have found online is that Born Free glass seem to be made in China, or some are, but the BPA free plastic ones are made in Israel. I threw my box away long ago or I would check mine for you.

Unsure what you are asking.... These melt clear though.... hope that helps.

Well, it seems others who've responded got crystal (I assume) clear ones, I didn't, mine are definitely diffused. Don't know why others report their's weren't. Could be people are used to blue or green or red diffused covers and these are, of course, colorless so they look more "clear," or the vendor is shipping different products. Don't know if that helps answer your question but again, yep, mine, all 49 (Got shorted by one LED) are diffused.

Those are not the files that I sell on Amazon. Those files are knock offs. Amazon co mingles inventory and I'm think you may have received files that are made in China. I'm so sorry. Please contact Amazon about this. All files that are being sold as Czech glass files have a small white sticker on the back of every white sheath.

No, unlike in the case of my Bodum glasses, there is no seal here. I don't think that these are from the same company. But mine work just fine.

When I ordered a smaller set version because I needed some more, I remember that the company on the package was Chinaglaze. Other than that information, I'm not really sure. The caps are plastic and I don't think they would sustain in high temperatures.

I can't tell you if they are nitrogen filled. I do wear glasses and am able to use them without my glasses because they focus really easily and clearly. I find this easier to do than with my glasses on.
