A viewing apparatus exhibiting high performance and an image forming apparatus including the same. The viewing apparatus includes a projection optical system for projecting an image on a viewer's eye, a detector for detecting the refractive power of the viewer's eye, and an adjustor for adjusting the projection optical system so that the image is formed substantially on a viewer's eye fundus. The imaging apparatus includes an imager for forming an image of an object, a projection optical system for projecting the object image on the viewer's eye, a detector for detecting the refractive power of the viewer's eye, and an adjustor for adjusting the projection optical system so that the object image is formed substantially on the viewer's eye fundus in accordance with the refractive power of the viewer's eye.

[ What is claimed is:] [1.] An observing apparatus having a projecting optical system for projecting an object image onto an eye of an observer, comprising:image detecting means for receiving a first reflection light from a fundus of the eye;controlling means for detecting the refracting power of the eye based on an output of said image detecting means, said controlling means including adjusting means for adjusting said observing apparatus so that the object image is substantially focused on the fundus of the eye based on a result of detection of the refracting power of the eye,wherein said image detecting means is disposed at a position in optical conjugation with a pupil of the eye such that a first image is formed in front of said image detecting means by the first reflection light from the eye fundus and a second image is formed on said image detecting means by a second reflection light from the pupil of the eye and from the neighborhood of the pupil;wherein said observing apparatus changes the distribution of the intensity of light on said image detecting means due to the first and second reflection light according to the refracting power of the eye and the direction of the visual axis of the eye; andwherein said controlling means detects both the refracting power of the eye and the direction of the visual axis of the eye based on the distribution of the intensity of light represented by the output of said image detecting means.
