Ophthalmologic characteristic measuring apparatus

Abstract

An object of the present invention is to provide an ophthalmologic characteristic measuring apparatus for precisely measuring optical characteristics of the eye to be examined and allowing the examiner to readily understand how an optotype is seen by the eye. The ophthalmologic characteristic measuring apparatus according to the present invention comprises an illuminating optical system for illuminating a microscopic area on the retina of the eye to be examined with light rays emitted from a light source unit; a light receiving optical system for guiding the light rays reflected from the retina of the eye to a light receiving unit; an arithmetic unit for determining optical characteristics of the eye including refractive powers and other components of the eye based on a signal from the light receiving unit, and calculating index image data representing the way in which a specified optotype is observed by the eye when a specified refractive power is corrected; and a display unit for displaying an index image representing the way in which the optotype is observed by the eye, based on the index image data.
