Slightly NSFW!
This type of headgear allows for clear visibility through most materials up to a distance of six feet. It is unable to pass through magical barriers, as well as any metals or materials that contain Aeum particles. The wearer must concentrate on something hidden behind a material in order for that substance to vanish from their sight, which necessitates extensive training and practise. Because a reattunement has the potential to break the item, Tinsel has opted not to remove the glasses unless this is absolutely necessary in an emergency.
The left glass penetrates substances, whilst the right glass provides information about whatever is in the field of view. What exactly is unknown because no one, with the exception of Tinsel, has ever used the goggles, and she has kept the details a secret from the rest of the world.
The object was part of a dungeon haul and was discovered in a collapsed underground location that existed prior to the Titan Wars. The G.E.F. owns three chests full of recovered relicts like this one, most of them are unidentified yet.

Tinsel often utilises the goggles to inspect individuals for weapons, peek into chests, search for hidden chambers and tunnels, and examine higher floors without having to physically travel up to those levels himself.
These are awesome goggles, love how you described them. However, when only one person ever used them, is rare then not a bit misleading? They are unique to Tinsel.
You are probable right. :)
