Something like this came up in Robert R. McCammon's 1987 book Swan Song[1], one of the first novels to win the Bram Stoker award[2] for Best Novel (alongside Stephen King's Misery that year).
One of the survivors finds a glass ring (something like trinitite) among the post-nuclear-blast rubble of Saks Fifth Avenue[3] in New York and sees visions of the future (or something) through it.
Swan Song, coincidentally, is getting a pilot as a TV series. I'm not sure if it's gotten stuck in development hell or if it's actually going somewhere, it's only been 18 months or so since screenwriting started.
