optometricist

Saw the eye doc today. Need a new script so I can replace my
glasses, which currently are at version 3 of my field improv.
I have a stiff nichrome wire looped around vestigital stubs
of the old nitinol templepieces. This does not provide adequate
constraint of rotation about the horizontal axis. My nose does.
But the loops of nichrome fall off the cm long stubs. So loops of
very flexible soft wire wrap the ends of the stubs as keepers
for the nichrome loops. "Sometimes" they also are wrapped around the
NiCr templepieces. But they break, so my nose is useful for horizontal
axis control. As stops, they seem to work fine --must be how wire
wrap used to work, soft wire around sharp edged pillars.

The eye doc's tech asked to measure my glasses, so I gave her the loop,
after a caveat not to laugh (which she laughed at until she saw my
hack). Then she showed the other receptionist declaring, "he must be
an engineer". I was impressed that she figured that out 8-)
