Abstract
In estimating the size of an isolated object by visual observation of its image as formed by a microscope objective, the characteristics of the eye as well as the physical light intensity distribution in the image must be taken into account. Experiments are described in which the visual sizes of circular objects of known size are measured as a function of the instrumental magnification, the retinal illumination and the adaptation of the eye, these results being discussed in relation to the corresponding diffraction images and the properties of the eye.Keywords
