ABSTRACT:
The present invention relates to an optical ocular system having imaging optics that map an image generated in an object plane such that a user can perceive the same in an image plane, wherein the imaging optics comprise a first lens having negative refractive power, and a deflection element having positive refractive power, which is connected downstream of the first lens, effecting a folding of the optical path by means of a single reflection, wherein the first lens and the object plane form a first optical group, and a displacement unit is provided, which can change the distance between the first optical group and the displacement element for the correction of spherical ametropia of the user.
