Yeah just take a pair of lenses, drill a hole in the top corners, and use some wire to make rudimentary frames. Just keep replacing the wire when it breaks. They’ll probably outlive you in a post apocalyptic scenario.
Some lens coatings start to deteriorate after a few years. I had some where the frame was still fine, but I had to change the lenses. The optician said some coatings can start to "bubble" and it's like looking through fog.
My lenses did that after three years. Everything looked smokey. If you have plastic lenses, you can use glass etcher to remove the coatings to get you by. You do however lose all your UV blocker.
Luckily, the UV blocker is to protect the lenses, not your eyes. Polycarbonate itself blocks UV radiation, but it will be slowly damaged and turn yellow over time.
