You shouldn't look at hot glass without glasses on either...we can't help it sometimes but try not to.

I have used both phillips and aura....
I only used the phillips for 1 day though cause my eyes were bleeding, and I had spots in my vision.... I don't need a chart either.  get the 5/7 split and some bright lights for your space. |

imo googles suck.
They get very uncomfortable after a few hours on me. I would get the carbon fiber frames if Mike still has em.... |

what about the old school plastic frames? I heard the metal frames tend to get hot , but the ?polycarbonate frames kick ass . I dont think these are poly c but I have some similar and they seem to be real damn comfy.

MIke,
Are IR coatings a safe method of IR filtration? I know the autochange welding helmets use coatings for IR filtration. I am interested in switching to a autochange helmet , can AURA make me a 2x4" KG3 filter to add to my helmet? |

"old school" plastic frames work quite well, however they will tend to soften if they get too warm - we insert the lenses in a salt pot whose temperature is about 250 F.
And yes, carbon fiber is dead. It was a huge success while it lasted, but people soon discovered that the frame material is quite brittle and broke when dropped. |

burnt - coatings last only so long as the coating remains intact. Once it is scratched, kiss your protection good bye.
Autochange helmets use an electrocharge filter to change color, which is usually based on an instantaneous change (for example when striking an arc) in light levels. I'm not sure that it will work for borosilicate lampworking. A KG-3 filter plate 2 x 4-1/4" will run about $120.00. KG-3 will block only IR, nothing else. |

just a thought in theory could you use a nice pair of sunglasses for the uv and ir protection they say they filter 98-100%of the crap ? also Mike which frames tend to be the most popular , do you have a polycarbonate or is that the carbon fiber that is spoke of , have you tried a form of neoprene ,stong, resists heat ,almost indestructable ,flexible , light weight list goes on . Have you had complaints with any of the frames ,get hot ,"brittle" ,heavy , what have you heard ? What are your most popular frames , goggs seem to smother me , no circulation .

ACK!!! No sunglasses!!!!!!! Never ever!!! (Well, let me back up a bit -- the only sunglasses that I would ever recommend for hot glass workers, and that would only be traditional glass blowers, are anything made with Bausch and Lomb G15. This is the only sunglass lens on the market that I am aware of that fully protects against IR.)
Sunglasses as a rule will protect you against UV but they do not protect against IR. If any sunglass manufacturer (except as noted above) claims to filter IR, ask for a transmission chart. Don't believe it until you see it in black and white. In order of popularity, by material: Polycarbonate frames: 9702 GW Goggle - this is our single most popular frame. 9803 Patriot Safety Frame. Not so popular but will fit over some prescription spectacles. Nylon: 0501 Biker Frame. We are starting to sell a lot of these. I've seen comments that this frame will fit over prescription glasses, but I can't imagine that they could. They fit very close to the face with a very strong wraparound fit. Zyl or optical plastic: 0101, 0102, 0103, 0203, W030. These are next in line in strength. Titanium: WT01, 02, 03 and 04. Lightweight/strong. Metal Stainless: WS01, 02, 03 and 04. Metal, strong Monel or optical metal: 0202, 0204, 9501, 9502. Metal, strong. Neoprene is not currently made in a frame material by any manufacturer. Carbon fiber, as I noted above, is not in wide circulation. If you can find a frame, good luck! It will work, but they are brittle and tend to break over time. If you have any more questions, please let me know! |

A while back I seem to recall a post saying that flip shades need to be repaced every 6mo to a year because they lose their effectiveness.
So, my first question, is that true? Second, if it is true, what prevents the shade on the expensive glasses from losing effectiveness and having to be replaced every year or two? |

if the flips are a plastic composite they wear out..... if they were glass they would probably last.... at least they better for then my octal flips would be useless. on the regular flips it's a coating applied to the lens with other glass lenses which are much thicker, the lens is one solid piece of glass made of that color glass

ok, thats cool.
Are the welder shades applied to a split shade, glass or plastic? they looked pretty thin for a glass lens. Mike |

Not quite.
Welder's flip ups are made of (usually) dyed polycarbonate. It is this dye that fades over time AND exposure to intense radiation. Glass filters have the filter as part of the glass matrix (iron is used), and it does not and cannot fade. The only lenses we sell (and make apart from the clip on flip up) are made of glass. We do not manufacture any plastic lenses. |

thanks, you have put my mind at ease and made it easier for me to replace my current didy/flip shade combo.
