Didymium glasses are the norm, and a must, for glass working, and are available in prescription lenses.  Chemical splash goggles can be worn over the didymium glasses when needed.

Subject: [DCHAS-L] Eye protection for working w/borosilicate glass

 

From:  phil_mckittrick**At_Symbol_Here**yahoo.com

 

One of our labs uses sealed borosilicate glass tubes for some experiments.  A tech seals several dozen of the tubes with a torch (I know he is using oxygen, I think the fuel is propane, I know it is not acetylene) at one time.  He was complaining about the brightness of the light, so is now wearing safety sunglasses that block 99+% UV.

 

Anyone have experience with something similar to this?  I have seen the didymium glasses that hobbyists use for glass blowing, but I am not sure what eye protection to provide.  He has tried welders goggles, but found them too dark.

 

Thanks,
