Nnngh. *pinches bridge of muzzle, beneath rapidly and poorly repaired glasses* I propose an OpenGlasses. The specs spec, if you will. Skeleton frame and arms, substantial adjustability and customizability across three standard deviations of humanoid head sizes via captive hex nuts/tapped holes and M1 hex-head bolts. Cheap to manufacture as backup frames for any lens. Flexible lens mounting strap? Screw mounts? Friction fit?
Mmnph.
Revisit when eyes not trying to unscrew selves from head. >.<
@Momentrabbit maybe hold the lens in with a zip tie around the rim, Ive used them to temporarily fit other kinds of lenses.
@Momentrabbit It's interesing to me that there's tons of equipment for finding the right prescription for you, but zero apparatus for adjusting glasses to fit. It's literally just "dunno, try some frames on, see what works".
