Abstract: The group of inventions is used for a medical clinical practice for automatically measuring a human eye abberation, determining a subjective visual acuity associated with the selection of a best spherocylindrical correction, investigating the influence of high orders aberrations on the visual acuity and for prognosticating the eye correction results. The inventive aberrometer comprises a point light source which is projected on the eye retina and forms a virtual source thereon whose radiation is dispersed by said retina and passes through the eye optical systems acquiring a phase modulation corresponding to the total eye optical aberration.
