I have used a similar version of NightFox IR goggles for many years for sheet film development in open trays, tanks & hangers, and loading tricky film reels. Invaluable, IMO. This pair, like mine, has a 1x optical zoom which I consider to be highly desirable because the view appears normal. My only initial concern with mine was the rubber eyecup. Since the internal screen is rather bright (with no way to adjust this on mine...maybe, this pair allows that?), I was concerned about light leaking out around the eyecup. My solution was to wear a neck gator and pull it up over my head such that the edges of the eyecup are covered. Probably looks pretty silly, but who's gonna see me in the dark?
