The image perception in humans depends on many factors. One of the most important ones is certainly the observing distance. The distance from which human look at the images is important for studying image perception in general and in particular on display devices. This paper describes a method of measurement of the preferred observing distance among humans of different age, sex, etc. under controlled conditions. The correlation between the distance and the visual acuity is presented and discussed as well.
