Some do. Sets with a 21FJP22 get the green cataracts since FJPs glue the entire inside of the safety glass to the entirety of the CRT face with clear glue that degraded and stops being clear. Sets with a 21FBP22 do not get cataracts since there is no glue. There is a black rubber spacer/dust gasket at the edge and the only thing that holds the safety glass on the CRT on FBPs is the clamping force of the CRT mounting hardware.
There's a 21GUP/GVP22 that's similar to and compatible with the FBP/FJP pair. IIRC the U is the gasketed and the V is the bonded version.
