The face shield in the video is a normal, passive, clear type, apart from being resistant to the arc flash. I think the flash is so brief that any eye problems would be temporary. The blackening is caused by the flash, metal and plastic vapour.
I don't think there is an automatic type welding visor that big, I know mine is a fraction of the size of the shield shown in the video and the largest I've seen are still substantially smaller.
The thing that shocked me the most is how common this arc flash danger is when working on industrial type installations. There are quite a few video's on youtube, some very disturbing to watch. Even highly trained technicians are seen to be making bad mistakes. I suppose it's easy to become complacent when someone has been doing the job for years without incident, so corners are cut and the odd's conspire against them.
