This is admittedly quite a sci-fi sunday sort of post, but something's been on my mind for a while now. In the context of the future, are visors on a helmet really any good? Yes, the full-faced visor view is a clear call back to astronauts, but those were there because technology like miniature cameras and displayers weren't invented at the time. Technically now if we wanted to we could build an EVA suit with a VR headset and cameras built in instead. And once the lag and field of view are improved, ditto military and combat helmets too. In fact they're already doing something like this in jet fighter helmets. In the future we often discuss this would be trivially easy and common place. And before you say "a transparent visor is redundancy in case of system failure!", that suit's air pumps are responsible for you breathing so if you didn't shield it against EMPs or hacking then you already got much bigger problems.

So is there really a need for a traditional see-through visor in helmets, especially for space or combat? Wouldn't it be more prudent to armor the faceplate and just have cameras/sensors?

#3 may go out of style in favor of the other options with smart VR/AR HUDs.
