A lot of the masks look a little too "Halo" owing to the wide lenses / face shields. Thus far, I have only thought of two work arounds: One, insert an amber tinted one and wear your patented goggles underneath. Or two, replace the clear lens / face shield with an opaque brass painted surface with eye holes cut out. The holes could be circular for WWI style gas mask lenses or half circles like on the Rocketeer helmet. They look like inverted sunglass lenses.

The paint ball mask I posted in the comment above retails in some places for $150, but I have seen it for forty. I only cited it as an example. You can find used styles for 20 bucks or less on ebay. Since it is just the foundation for homemade doohickeys, it probably wont matter what style you start with.
