Not necessarily lasting physical damage, but flickering CRTs, or for that matter flickering fluorescent or LED lights can cause headaches, nausea, ... I've certainly noticed it myself, using 75 Hz CRTs made me feel tired after a few hours, unlike 85 Hz. > In 1989, my colleagues and I compared fluorescent lighting that flickered 100 times a second with lights that appeared the same but didn’t flicker. We found that office workers were half as likely on average to experience headaches under the non-flickering lights. https://www1.essex.ac.uk/psychology/overlays/1989-82.pdf |
