                set of optical simulators of the human eye, produced from a
                high-quality optical glass, is intended for calibration of
                various ophthalmologic instruments, including aberroscopes (the
                set comes along with the MultiSpot), autorefractors, and
                keratometers. The reflectance of the artificial eyes' back
                surface for the near IR range corresponds to that of the human
                retina. The optical power of the eye can vary within the 20 D
                range, zero corresponding to the "ideal" eye focused
                at infinity. |  |
