Or just needing (and appreciating) the attention of kindly people at an
understandably difficult time in bereavement.

It's not the issue of the glasses non-functioning, it's the repairer -
and the sentiment that these were the personal items that _he_ fixed
might be something stopping her from letting the item go.

A friend that went through the same, was initially demanding with all
sorts of things that she soon managed to sort out for herself and her
satisfaction, having time to think. Events are going at an unwelcome
rush at the moment, and rash decisions... well... :-(

For the OP, Time will heal. Do a patch up job for now, and later down
the line maybe help her get a new set done.
