Safety Glasses

Hey all,

I seem to be having trouble searching the forum for "safety glasses". I remember a discussion, but can't find it. Anyway...

I know about Aura Lens and I don't want to get into a discussion about them, but I was wondering who knows about other places to get perscription safety glasses that will block IR and give me a little shade.

?

Rick

These guys specialize in IR blocking for lasers and such, the clip on's are about $45 and come in al types of color/shades. I've been told to watch out for didymium as it is not great for IR

check out safetyglassesusa.com and search for "IR". Lots of good options below $10.

glasses

My local eyeglass shop does a lot of prescription safety glasses for welding. They use a bosh and lome (spelling?) product.

aura lens debacle

I called Aura lens five times, waited over 2 months, over 300 bucks for my prescription, they finally show up, and the lenses are two different colors!

Are they split lens being top one shade and the bottom the other or are you saying two different Lens from left to right?

Well, now you can play pirate. I really don't know what happened to Mike. It's certainly not possible to recommend Aura as a source anymore.

Wow that's really bad. I know Mike went through a bunch of drama but from what I've been hearing he's trying to pull it together. I don't think that's acceptable at all how long has it been? I certainly wouldn't settle for that. Obviously someone screwed up. Welding filters and suppliers have been spotty and I know Mike just found a new source. Maybe you got stuck in the middle.

What's the deal with the best type of glasses to use anyway? I have a pair of didymium sand my girlfriend has a pair of welding glasses. She was told by an optimologist that welding glasses were best... I disagree.

For torchwork you need the neodymium lense to damp down the UV and sodium flame and in some cases, the IR. I do not know why they call that Didymium. There is no such element. . For furnace work a number three welders lens is more than sufficient. Any darker and you'll get lost in the studio. Mike used to tell me that ordinary glasses were actually quite adequate in normal furnace work. Your eyes have no nerve ends that can sense heat but they still get burned so a simple reflective surface like clear glass handles most stuff.

Please send checks to me at....

There seems to be so much misinformation about this issue. As I understand it, as furnace workers, unless you're running your glory hole as hot as the sun, we're not exposed to that much dangerous IR. We definitely don't need anything that cuts sodium flare like didymium since we don't sit in front of a oxy/propane torch for hours. So why the fancy dark glasses?

Before I understood the above I bought an expensive pair of #3 welding shades to blow glass but they were crazy dark and I think totally unnecessary. Now I use them as sunglasses when I walk to the local taqueria to grab lunch.

The glasses I've settled on use block 75% of IR, 99% of UVA and UVB, are super light, are fairly light colored and cost....drumroll...$10.65. If you'd prefer to spend $200 so you feel you're really protecting your eyes, feel free to send me a check and I'll send you a half dozen of these glasses. The balance is my fee.

The problem mainly exists for people who need prescription lenses. That's when the consumer protection division has monkeys in the sacred temple. It's a sales project to get people to buy what they really don't need.

Didymium (Greek: twin element) is a mixture of the elements praseodymium and neodymium.

I use a shade 2.5 from the same safetyglassesusa. They had a yellow lens that was rated to a 2 welding shade that I loved but they don't carry them anymore.

We have had nothing but good luck with Aura Lens... I'm suprised to hear people are having problems. We've ordered and received a half dozen pair of glasses in the last couple of months a couple of them repairs from dropping them etc and they were all as ordered and prompt...

***********
It would have to be a profoundly tiny amount of praseodymium then. Last time I bought lenses, Neodymium was about $8.00 lb and Praseodymium was $2,500.00 lb. Both have gone up. I think that the word is used but not the actual compound.

As to the issues with Aura. Initially I discounted the complaints but we sure have had a bunch of them. You can't help but notice.

Interesting read from what I gathered.
Didymium was once thought to be an element and was given the DI. Then it was discovered it is actually two elements combined.

So how could that be did someone make it then die with the secret. Later to be closely examined and found to be two elements?

I also wonder if you just had a lens of neodymium would it work the same. All research leads me to more questions them answers.

So maybe someone could let Mike know we have unanswered questions and some costumer problems. I would love to hear what Mike knows of this mysterious mixture. I would also love to see Mike make more happy customers. I have at least a dozen pairs of his filters and really can't say anything but good things personally.

When I was 18, a long time ago, they called these things Neodymium. At that time, the technology did not exist to do certain separations and Neodymium was really expensive. Then, it became a byproduct of another process and the same thing happened to Selenium and the price fell. At one time I paid $4.50 lb for Selenium. Praseodymium has always been really rare in reality and very difficult to process, thus the high cost.

While I would love to hear from Mike since the best thing to combat bad press is by being honest about the issues, I think that the lens are neodymium and neodymium only, or an ever so tiny portion of praseodymium they just couldn't extract from the compound.

The only thing I know there is that there were some serious health issues for a family member. I do not know more.

Artco sells the 'reader' glasses if they're at all appropriate.

The main issue has always been getting them in a prescription

Which brings up the question in my mind - is it a coating or a tint in the actual lens material? If it's a coating it sure would be nice to get it done to a prescription pair that you already have, and if it's the lens material is it only available through one supplier? That almost doesn't seem possible.

Hoya makes a lot of Neodymium glass. Schott used to do a lot but they had not been able to underbid Hoya for years.I have a lot of neodymium slab glass as in 100's of pounds. It all is like 2x12"s three feet long.

I have not bought lenses in thirty years. They used to all be glass and for me were quite heavy. If they're plastic, it isn't neodymium doped anyway or I certainly don't know how that would be done.
