Infrared eye protection is important for glassblowers looking at molten glass [1]. Back of the envelope math suggests that an occupation that required staring at an intense fire for long periods of time would violate the same workplace safety thresholds, but I have not been able to locate any studies that specifically investigated looking at fire. There are a surprising number of different jobs that involve staring at incandescence from molten glass or metal, but I think the most interesting is an operator of a disappearing-filament pyrometer [2].
