Had to solder my nose piece yesterday, after bending it to stop rubbing against my eyebrows.
You can probably barely tell, but yes I had to solder that spot in the center of the photo (right nose piece), on glasses made in 1988.
I had to do a little mild bending, which already scared me, to take the lenses about a millimeter away from my nose bridge, to stop from rubbing against my eyebrows.
The right nose piece started to weaken and almost broke off, so I cleaned that with a Dremel and soldered it to reinforce it.
Sorry the photo angle is a bit dim, but it came out solid and clean ๐
Solder as in silver brazing? Tin brazing? or a spot weld? Did you take out the lenses? If they're plastic, they won't like the heat if it's silver brazed.
No worries: unless you used a really old roll of solder, or stuff exempt from the lead ban for special applications (usually military), it's lead-free.
