I suspect some sort of bond between a rather thin

early RCA versions of this called "Pan-o-ply"?). Without the bond,
an imploding CRT would likely shatter the lens also. So, while this
gets rid of the "cataract", I think there's a compromise in safety.
Makes sense. What about the stuff they use to "repair" cracked car
windscreens? It's got much the same refractive index as glass (you can
*just* see distinctive "flower shapes" if you look, around a repaired
chip), and is flexible enough to move with the glass but strong enough
to stick the glass and plastic sheet together.
