Some people wear clear plastic faceshields in lieu of fabric or
masks. Good for less restricted breathing, keeps you
touching your face. Also helpful if you work with the hearing
impaired, so they can read your lips. But a face shield is
kinda bulky - where do you
you're NOT wearing it?
Most are pre-shaped into a curve, or shipped flat and can be
enough to fit around your face. In either case they're not much
more flexible than that. I'd suggest making them of an even
plastic so they can be rolled into a skinny tube for storage and
held in that
shape with the headband. If you ever need to carry it around
when you're not wearing it, you could hang it from your belt
(reminds me of 20th century slide rule cases).
The trick would be finding just the right
thickness and flexibility.
Possibly could be repurposed
A clear plastic report cover, and maybe some rubber bands. [kdf, Jul 23 2020]
This shape could probably be made collapsible.

||What about a venetian-blind type design, that can be pulled up into a thin, flat bar ?
||Flipping it up gets it off your face for the time being, but
you're still wearing it. Probably good for some situations
(eating, drinking, going from place to place where a shield
isn't needed) but not what I was going for here (e.g.,
stowing it when you're NOT wearing it.
||Not sure how the Venetian blind thing would work as a face
shield. Needs to be solid enough to divert air flow. A
simple folding thing without slats might be hard to see
through, depends where the creases are.
||It could be made like a top hat, with the "shield" part able to "concertina" up under the brim when not in use, and providing all-round protection when deployed.
||Hook-and-loop fastening could stick the lower rim of the screen to the user's upper garments when in use.
||"Like a top hat / concertina" ... might work and
not look any
sillier than current implementations. Still not sure
manage visibility through the creases.
||Tinted Venetians? Might have a sunglasses thing there.
||So roll it up scroll style, hmmm. I like.
