I love getting my eyes bombarded with the occasional ionization electron beam fired from the electron gun that make it past the phosphorescent screen.

I do not envy some of the ocular conditions some of the old long-time programmers in the industry had, although this is from personal experience. All CRTs generate Xrays, even if later on regulation would attempt to minimize the amount generated. and using them should still mean keeping your distance. The effects it has on your eyes are not instant, specially if you don't use them as part of your job.

A lot of the excessive warning from screens came from this era, where there was an actual risk. Unfortunately, there are planty of antivax-like CRT-radiation deniers, but fortunately, it's no longer a problem.
