I'd like to see looking_over_glasses expanded and broadened. The suggestion I'm sitting at is an alias set to one of the following:
Benefit of the former is they lend easily to *glasses* searches; benefit of the latter is they more readily qualify sunglasses (even monocles!). In either case, I see the tag(s) extending so far as being that if the character's view could be through the lenses, even if the eyewear isn't resting in place (pulled forward, held in front of face), but it's instead relatively closely outside of the lenses, the tag is applied.
Not sure about an upright, forward face angling their eyes fully up/down/sideways, though, since the lenses wouldn't be facing those ways.
