We evaluated viewing distance vs. TV size on visual fatigue using two kinds of visual content: a 42-inch PDP display (Experiments 1 and 2), and the effect of TV size on visual fatigue with a 65-inch PDP display (Experiment 3). The results indicate that optimum viewing distance for less visual fatigue lies between 165 and 220 cm, indicating as a semi-absolute distance, rather than the strict relative distance like three times of the screen height (3H).
