I have a bunch of computer CRT monitors and the only way to get bad refresh rate that you actually notice is to set them at 60Hz. At 70Hz or above (most can do 85Hz, any good CRT monitor should be able to go above that) you wont have any issues.
Also while this can cause eye fatigue (which depends from person to person), i could never find any proof (and i just did a quick search) that there is any sort of permanent eye damage.
