Trope-a-Day: Goggles Do Something Unusual

Goggles Do Something Unusual: Since medical technology has long since adapted to the point of being able to fix just about any eye problem imaginable, any time you see glasses on someone’s face – and there are periods of history where you will see this quite a lot – you might suspect that they’re there to serve some other function.

You would be right.  Usually, that function’s just acting as I/O for a wearable or other PAD devices, which means that they combine a head-up display with stereo cameras (these enable augmented reality, freeze-frame, enhance and rewind, among other things; and even when neural laces replaced wearables, a lot of people kept them around as a popular way to lifelog), microphones, eye tracking, and ability to participate in a wireless PAD (such that they can communicate with your wearable, but also with any other networked devices you might be carrying, which is probably all of them; your gun, for example, certainly uses them as a scope) including a gateway to the greater network and all its facilities.

Of course, technological ingenuity being what it is, there could be anything from a T-ray scanner through a general-EM reader to a full SQUID in there, sensorily speaking, or a couple of nanomissiles or a few BIPS of processing power concealed in the frame.  It’s really best not to assume what the chap with the glasses might or might not be capable of seeing.
