Welders might buy this - they already have auto-darkening helmets, they might be interested in something that darkened only part of the field of vision.
Of course you would have to be very careful on the design, since a failure would be very hazardous.
Exactly what I thought. A welder helmet is large enough to easily fit the electronics inside, plus as a professional product the price point may be somewhat less sensitive. Would make sense as a first, preliminary product.
Yeah, it's not the visible spectrum that's harmful to your eyes. If you filter out all of the harmful frequencies entirely, you can selectively filter the visible spectrum for convenience while retaining a non-disastrous failure mode.

This tech proposes the use of LCD's, and I don't think a blackened LCD can provide the requisite protection from the radiation produced by welders.
They exist - google for auto darkening helmet, and they use LCDs.
The UV and infrared are always filtered (by the glass), and the LCD handles darkening the visible light.
