    Default UV Glasses for Mc Gizmo UV lights

    What do we use to protect our eyes rom the 365nm for Norland curing? 3M makes many different ones, and it gets confusing?

    I want to get a UV from Don, but need some glasses to go with it, any advice would be welcome?

    Thanks,

    RL

    Subscribed, I've got a UV LED from Don, I try not to look at the light as I'm curing Norland, but I also use it sometimes taking photos...

    So - also wondering what I should be doing...

    I was disappointed with the effectiveness of "regular" UV blocking glasses, but laser-certified lenses/goggles ( @365nm ) appear to provide much greater intensity reduction.

    Very expensive, however.

    The yellow lenses from 3M safety glasses are pretty good for moderate protection. Much better than nothing.

    Yes, but we need the best protection, you don't want to have something that glows for 40 years that you can't see in 10 years?

    3M must make dozens of pairs, and while I love their products, their customer service is awful, when I called to find out about the different colors of Scotch Brite Pads, the guy on the phone said, "To be honest we make so any different colors, I can't answer your question, I don't know the difference in the colors."

    I really miss miss the old phones you could slam down, like Jerry Seinfeld said 'How do we slam cordless phones down?' And now cell phones?

    Called the Minnesota Secretary of State, and got the direct numbers to the CEO, President, and VP. Backdrop phone lines! A trick my wife taught me.

    These big big companies think they can give answers like that? My trick is find out when their annual meeting is, go there and dress nice, then walk right up to the Chairman. Always being a gentleman, of course. I just wanted an answer. This was a different company. The chairman, being so amazed at what I had done, invited me to go to dinner with them. Oh, and I got my answer!

    There are quite a few ... a web search for laser safety glasses reveals several large manufacturers.

    They are generally rated by "OD" (optical density) , a term with which you likely are already familiar

    I think some of the light curing bonding agents work on higher wavelengths like royal blue. I understand most glasses provide significant UV protection but nothing is better than simply not looking at the light or its reflection if it can be avoided. I don't know if any of you guys have used Bondic but I picked some up and am real happy with how quickly it cures and suspect it would be a viable alternative to the Norland. They don't specify what wavelength their little 5 mm LED is but considering how quickly the material cures using their LED, it would seem that exposure to UV with their system is pretty marginal. I have found that the Bondic cures very fast with the 365 nm Nichia and I just look away when I fire up the LED and hold it on for a few seconds.

    Since it could be considered safety equipment, it may be prudent for individuals to research their own specific needs and suitability.

    Do NOT buy unless you know exactly what it is you're buying. If you have the slightest doubt then it's time for more reading. Those things are REALLY expensive, so it's going to hurt in more than one way if you get the wrong thing.

    To get a set with too weak of an OD gives a false sense of protection.

    Good luck!

    Thank you for the replies, and I do agree with you gentlemen on the research factor.

    Let me pose this question, keeping in mind I know nothing about this subject, but is closing your eyes or looking down with a pair of glasses you feel might be rated, and as awful as that sounds, it is simply a question.

    Wait...I thought this was the Information Age, quick someone call Vice President Gore, surely he must know as the inventor of the information superhighway!

    But, seriously guys, we need to get this right it is much to serious and final if we don't do, it right!

    Does anyone have insight as to what other industries that use the UV light as we do? At least as a starting point? I will start looking into it, however, I am always called away for things, and don't get back to things like this as quickly as I would like, so any additional help would be great, and we have some very bright people in this thread, not to mention the entire forum.

    Thank you all for your help, once we get it figured out for certain, it will help future generations looking for the same information in the for years to come.

    You know, in the past you could call high tech companies and get really good answers from people, on the phone, now if you try to ask a technical question, you are asked: well, who are you, why do you want to know? Like we are Al Qaeda, asking. Very frustrating

    I was thinking of calling MIT, Stanford, Cal-Tech., NASA, Boeing and others to see how far I can get? You never know. It really is a very simple question.

    Let's try to keep this one going for our own safety, and safety of others who like Trit. Vials. They are fun and I love them, as do many here!

    As always, best wishes to the good people on CPF,

    Very good advice here.

    Look, those of us in the custom light arena are spending quite a bit of Money on some of the finest items ever made in their class in the world - bar none, and it just makes sense to spend money on the best set of UV glasses, really, why stop there?

    I think if we work collectively on this together we will find the product we are looking for, and I would be willing to even loan mine out to someone with a good standing here in the board to complete a small project of vial installation as they may be expensive and I would not mind doing that as I will not be using them in an everyday manner, I just want the proper pair, and would loan them out so someone's eyes don't get ruined for a hobby.

    Really, I am confident we will find what we are looking for!

    As always, yours's in McGizmo,

    You'd need to know the power of the source, and then calculations of reflected UV could be postulated.

    The lenses used for lasers are obviously going to have very high optical density, due to the concentration of the beams, and the same OD rating may be a bit conservative for a non-coherent beam.

    The OD rating is needed for the particular wavelength RANGE (UV LED will NOT be emitting a single wavelength, hence the portion of visible light too, etc), so a lens may be rated at different OD for different wave lengths, etc.

    The advantage to the curing scenario is that the superfluous wavelengths can at least help you aim/tell you where you're curing, etc...as the specific OD means, typically, that you can't see the wavelength of concern (As THAT'S the one being blocked...)...so, the lower OD wavelengths are what you SEE by.

    Eagle Pair makes some (relatively) inexpensive, yet at least rated, safety goggles/glasses. Noir makes better (more expensive, etc) ones...the $ going towards higher OD and better light transmission, etc.

    The 195 - 540 nm versions would be a typical range inclusive of the 365 UV range.

    If and only if the OD (optical density) rating is correct for the intensity of your particular use.

    The problem with having 1 set of eye shields and loaning them out is that you cannot guarantee that the intensity of the light source they are using is not as bright as the intensity of YOUR light source or even the same wavelength.

    2 criteria for eye protection:
    1. The eye shields must block ALL of the wavelengths you're working with.
    2. The "darkness" aka "optical density" of the lenses must be dense/dark enough to actually do anything.

    Sunglasses for this are out of the question. Your irises will dilate and make you more vulnerable to bad frequencies, sunglasses are some of the worst eye protection out there. They love making false claims like "blocks 100% UVA UVB." BS. They didn't say at what intensity.

    Hope that made sense.

    Yes, you put that in clear terms even someone like myself with no real study in this field understood? Also, I have never thought the claims to sunglasses to be true, the advertisers lie. I had to have cataract surgery when I was 39, and always wore good quality sunglasses from the optometrist. I fact, I have to have it all re done soon.

    How do we go about researching this? So many in academia tell you things so wrong, but of course they in their own minds are never wrong, ever, and could never, ever be wrong. My wife is an academic and I have to correct her on things all the time. (Say, don't take this wrong if you have an advanced degree, I think if you do, you will understand where I am coming from). However, please continue with this as many of our friends here could be doing damage they don't understand fully, and that's not good...Trit vials are too cool not have over a pair of glasses.

    So, are you saying we need an exact pair for 365 nm? That I was not completely clear on, but you put the rest in a nice focus of understanding.

    You know, your code name here on the forums involves vampires, if you know any maybe they could do the work for us! they seem to be able to see in the dark, keep late hours and have eyes exempt from UV, only bright sunlight, and could have a side line in the Trit. Vial install industry! Would they take blood as payment for these services? Plus they are always well spoken with a good command of the language, most polite, and wear some pretty sharp threads, always perfectly dressed, in some cases over dressed and very well groomed.

    They all have impeccable taste, and seem to be brought up in good homes, and are very well educated. Except for the biting thing they would make great neighbors, I bet their lawns are perfect, and they drive nice cars, or no, wait they fly? Right?

    All, joking and kidding around aside, the UV thing is a serious matter, and you seem to know about this subject, and I thank you for your help. And hope you will continue to help us find the protection we are looking for and need.

    Thank you so much,

    With all best wishes,

    Appreciate the kind words, RL.

    To clarify the clarification

    The laser eye shields aren't cut-and-dry 365nm and no other frequency. Noir has a great many charts and charts and charts showing the RANGE of wavelengths blocked and what ranges are transmitted through the eye shield. To go with the example, there is no "365nm eye shield."

    https://en.wikipedia.org/wiki/Laser_safety
    Wavelength range Pathological effect
    180–315 nm (UV-B, UV-C) photokeratitis (inflammation of the cornea, equivalent to sunburn)
    315–400 nm (UV-A) photochemical cataract (clouding of the eye lens)
    400–780 nm (visible) photochemical damage to the retina, retinal burn
    780–1400 nm (near-IR) cataract, retinal burn
    1.4–3.0μm (IR) aqueous flare (protein in the aqueous humour), cataract, corneal burn
    3.0 μm–1 mm corneal burn
    --------------------
    Maximum permissible exposure
    The maximum permissible exposure (MPE) is the highest power or energy density (in W/cm2 or J/cm2) of a light source that is considered safe, i.e. that has a negligible probability for creating damage. It is usually about 10% of the dose that has a 50% chance of creating damage[7] under worst-case conditions. The MPE is measured at the cornea of the human eye or at the skin, for a given wavelength and exposure time.
    -------------------
    The use of eye protection when operating lasers of classes 3B and 4 in a manner that may result in eye exposure in excess of the MPE is required in the workplace by the U.S. Occupational Safety and Health Administration.

    Protective eyewear in the form of spectacles or goggles with appropriately filtering optics can protect the eyes from the reflected or scattered laser light with a hazardous beam power, as well as from direct exposure to a laser beam. Eyewear must be selected for the specific type of laser, to block or attenuate in the appropriate wavelength range. For example, eyewear absorbing 532 nm typically has an orange appearance, transmitting wavelengths larger than 550 nm. Such eyewear would be useless as protection against a laser emitting at 800 nm. Furthermore, some lasers emit more than one wavelength of light, and this may be a particular problem with some less expensive frequency-doubled lasers, such as 532 nm "green laser pointers" which are commonly pumped by 808 nm infrared laser diodes, and also generate an intermediate 1064 nm laser beam which is used to produce the final 532 nm output. If the IR radiation is allowed into the beam, which happens in some green laser pointers, it will in general not be blocked by regular red or orange colored protective eyewear designed for pure green or already IR-filtered beam. Special YAG laser and dual-frequency eyewear is available for work with frequency-doubled YAG and other IR lasers which have a visible beam, but it is more expensive, and IR-pumped green laser products do not always specify whether such extra protection is needed.[24]

    Eyewear is rated for optical density (OD), which is the base-10 logarithm of the attenuation factor by which the optical filter reduces beam power. For example, eyewear with OD 3 will reduce the beam power in the specified wavelength range by a factor of 1,000. In addition to an optical density sufficient to reduce beam power to below the maximum permissible exposure (see above), laser eyewear used where direct beam exposure is possible should be able to withstand a direct hit from the laser beam without breaking. The protective specifications (wavelengths and optical densities) are usually printed on the goggles, generally near the top of the unit. In the European Community, manufacturers are required by European standard EN 207 to specify the maximum power rating rather than the optical density.
    Whew! There's a mountain of this stuff to sift through. Really looks extremely easy to pick the wrong eye shields, waste a couple hundred bucks and have a false sense of protection.

    I spent a few minutes hunting for 365nm glasses, I flipped through about 50 spec sheets. Haven't found one I'd call suitable yet.

    Research, research, and research some more. Strongest I've found yet is OD7, but don't like the ranges I'm seeing.

    I need some broad spectrum UV protection for working with home made carbon filament incan and carbon arc, so I'm working towards this as well. I'm along for the ride.

    I'm leaning towards welding goggles as arc welding is pretty much like working with carbon arc.

    https://en.wikipedia.org/wiki/Arc_welding#Eye_damage
    Exposure to the brightness of the weld area leads to a condition called arc eye in which ultraviolet light causes inflammation of the cornea and can burn the retinas of the eyes. Welding goggles and helmets with dark face plates—much darker than those in sunglasses or oxy-fuel goggles—are worn to prevent this exposure. In recent years, new helmet models have been produced featuring a face plate which automatically self-darkens electronically.[16] To protect bystanders, transparent welding curtains often surround the welding area. These curtains, made of a polyvinyl chloride plastic film, shield nearby workers from exposure to the UV light from the electric arc.[17]
    CPFer FritzHID tells me that he likes #12 welding eyewear for working with arc, which provides broad spectrum uv. I've actually got goggles and a full face mask, but was looking for high end glasses.

    What are the symptoms of "Arc Eye?"
    http://www.ccohs.ca/oshanswers/safet...ding/eyes.html
    Certain types of UV radiation can produce an injury to the surface and mucous membrane (conjunctiva) of the eye called "arc eye," "welders' eye" or "arc flash." These names are common names for "conjunctivitis" - an inflammation of the mucous membrane of the front of the eye. The symptoms include:


    • pain - ranging from a mild feeling of pressure in the eyes to intense pain in severe instances
    • tearing and reddening of the eye and membranes around the eye
    • sensation of "sand in the eye" or abnormal sensitivity to light
    • inability to look at light sources (photophobia)

    The amount of time required to cause these effects depends on several factors such as the intensity of the radiation, the distance from the welding arc, the angle at which the radiation enters the eye, and type of eye protection that the welder or bystander is using. However, exposure to just a few seconds of intense UV light can cause arc eye. These symptoms may not be felt until several hours after exposure.
    This is when you know you've got a problem, but it's already too late.

    Blocking UV with regular glass:

    This is super hit-and-miss. Some glass is effectively transparent to UV, some not. Most glass won't stop broad spectrum UV, but it can help.
    https://en.wikipedia.org/wiki/Ultraviolet
    Ordinary window glass passes about 90% of the light above 350 nm, but blocks over 90% of the light below 300 nm.[22][23][24]
    http://donklipstein.com/carbarc.html
    The UV content contains significant UV-B and some UV-C (shortwave UV) which is hazardous to skin and eyes. Ordinary glass stops these, but plenty of UV-A (longwave UV) gets through glass, and this may be hazardous to eyes at high intensities.
    So at 365nm, we cannot use regular window glass.

    http://www.curtain-and-divider.com/i...rtain-walls-2/
    Welding curtain walls generally cover larger areas where it is not feasible to use portable welding screens. These curtains are fabricated from Vinyl which will block the harmful UV rays from welding
    If it can stop broad spectrum UV from arc welding, it can stop 365nm.

    Since the light is non-collimated, this may or may not be enough. Not sure yet.

    I'm still thinking that arc welding goggles but NOT gas welding goggles would be the ticket.
    https://en.wikipedia.org/wiki/Welding_goggles
    Welding and cutting processes, including arc welding and cutting, as well as brazing produce intense ultraviolet (UV), infrared (IR) and visible light wavelengths. The UV and IR wavelengths cannot be seen and can produce eye injury without the victim realizing it immediately. Extremely dark filters of the proper sort are needed for the welder to be able to look at the intensely glowing metal being welded.
    Auto dim eye gear will likely not trip with a UV light as it's looking for the arc striking. It won't "turn on," most likely.
    A filter suitable for gas welding, for instance, should not be used for arc welding. Face masks which are self dimming are available for arc welding, MIG, TIG and plasma cutting, and allow better vision before the arc is struck and after it is extinguished.[6]
    Still hunting high end laser eye glasses.

    To clarify the clarification

    The laser eye shields aren't cut-and-dry 365nm and no other frequency. Noir has a great many charts and charts and charts showing the RANGE of wavelengths blocked and what ranges are transmitted through the eye shield. To go with the example, there is no "365nm eye shield."

    https://en.wikipedia.org/wiki/Laser_safety
    Wavelength range Pathological effect
    180–315 nm (UV-B, UV-C) photokeratitis (inflammation of the cornea, equivalent to sunburn)
    315–400 nm (UV-A) photochemical cataract (clouding of the eye lens)
    400–780 nm (visible) photochemical damage to the retina, retinal burn
    780–1400 nm (near-IR) cataract, retinal burn
    1.4–3.0μm (IR) aqueous flare (protein in the aqueous humour), cataract, corneal burn
    3.0 μm–1 mm corneal burn
    --------------------

    -------------------


    Whew! There's a mountain of this stuff to sift through. Really looks extremely easy to pick the wrong eye shields, waste a couple hundred bucks and have a false sense of protection.

    I spent a few minutes hunting for 365nm glasses, I flipped through about 50 spec sheets. Haven't found one I'd call suitable yet.

    Research, research, and research some more. Strongest I've found yet is OD7, but don't like the ranges I'm seeing.

    I need some broad spectrum UV protection for working with home made carbon filament incan and carbon arc, so I'm working towards this as well. I'm along for the ride.

    I'm leaning towards welding goggles as arc welding is pretty much like working with carbon arc.

    Thank you so much for doing this, I know it is a lot of work, however, overall, it is a good thing for our members who like to install these vials, and it is something I want to work on not just for myself but all the proper presently doing this but, for future Trit. vial installers, some which be unaware that this causes serious and in some cases irepairable damage to their vision.

    This could be the most importation and prolific sticky ever to be posted here.

    So, could Arc welding goggles work, or could? Also just as an example, for the short duration we zap the vials with UV, could some of the better glasses work for that duration or is damage done in an instant?

    Once again thanks for the work, I think it is very important work which I and I am sure many others here appreciate very much, I know I do. I will also keep working in it as well.

    Thanks again,

    RL

    No problem, friends! I used to be a resident on Answers.com. Old habits die hard. We fight together towards the answer. We relish dispelling the darkness.

    Never my intention, in a lot of ways I'm just sharing what I'm reading and enjoy posting it in a thread that's appropriate. Glad to help. It's enjoyable to find a thread where we have common goals, that's a community right there.

    Damage is cumulative and gets worse the more exposure you get. It's a lot like a sunburn inside your eyes.

    Yeah, I'm absolutely positive that ARC welding goggles (but not oxy-ace goggles) would do it. The thing I'm grappling is the cut-off. How light of a shade can we go so as not to trip and fall because we can't see, yet still be protected. The UV damage is sort of an ongoing thing. How long is the curing exposure anyway? If the UV is intense enough, you can get a sunburn from it and need to cover up exposed skin in addition to eye protection.

    I'm looking at all options I can think of or find. The welding curtains (not all will block UV) might do it for a non-collimated UV light, but I don't have all that info yet.

    The right laser UV glasses will be major overkill, but safe. You'll be able to see almost normally as well with some models. It's going to look pretty dark with arc goggles, there is a tripping hazard.

    Well, I just called 3M, and this is what they told me, and I am a skeptic with big companies, they told am ANY of their UV glasses are the tested from 200nm to 380nm, I told them I was working with 365nm, and they said I should be good to as these were the most dangerous of the UV ratings, and anything below 280nm all the way through all the UV spectrums would be safe.

    Really? I just don't know. What do you think? I am not ready to believe this at this point in time. I feel like calling back and talking to someone other than a CS Rep.

    Maybe check with an optometrist or call a medical college that specializes in eyes and ask them and see what they say?

    The jewel in the thread for me - of course I just order some more Norland on the weekend, but this looks pretty good.

    I wonder if Norland has any information on UV goggles?
