Uvex makes lots of nice safety goggles with various types of protection. Just go on amazon and search for "Uvex genesis". They have ones with a shade 3 welding lens, low-ir type lens, and a gray tinted lens that all do well against IR, along with many other variations.
Here is a link to the PDF of their catalog showing transmission spectra, visible light passed through, and everything else you could ever want to know about selecting eyewear: http://www.uvex.us/uploadedFiles/ProductConfiguration/ProductLiterature/Uvex_Lens_Tech_Update2011.pdf
Personally I'm probably going to buy all three of the ones I listed above (a set with shade 3, a set with the low ir lens, and a set of dark grey) so that I can switch to whatever I need for the situation. There is a local place I take classes that has very little light and is outdoors with classes at night, I'm planning on using the Low IR ones here so I can see better. Once I get my stuff setup in my back yard I'll use the gray lens since I'll be working outside during the day so I'll use the gray lens, possibly switching to the shade 3 when forge welding for a little extra protection.
Eye protection is CHEAP! I've learned over the years that I must have some kind of gravitational pull for debris to fly into my eyes at inopportune moments so I always wear safety glasses no matter what I'm doing. I know too well what nasty corneal abbrasions feel like, a $10 dollar set of throw away saftey glasses once or twice a year is a no brainer to me. You only get one pair of eyes!
