摘要： A subject is placed in a more natural state or is encouraged to blink at specified intervals to obtain a measurement result under a fixed condition, and the judgment of the degree of dry eye is facilitated. A measurement part obtains, based on a reflected light flux from a subject eye, optical characteristic data of a two-dimensional vector form representing the time course of each optical characteristic of the subject eye in an blink interval from a certain blink to a next blink with respect to the first to the nth blink intervals. An analysis part one-dimensionally arranges each of the optical characteristic data with respect to the first to the nth blink intervals measured by the measurement part, and arranges the one-dimensional arrangement of the optical characteristic in a p-th blink interval at a p column to create a two-dimensional array, and performs a principal component analysis processing on the two-dimensional array.

摘要： A visual target presenting optical system has a light source that illuminates a visual target to be viewed by a subject, and a visual target presentation state changing unit that can change the direction in which the visual target will be presented to the subject. An alignment luminous flux casting unit casts an alignment luminous flux toward a subject eye at timing prior to the presentation of the visual target. An alignment light receiving optical system and a light receiving unit receive a reflected luminous flux from the subject eye reflecting the luminous flux. A change control unit instructs the visual target presentation state changing unit to change the visual target presenting direction on the basis of the light receiving position of the reflected luminous fluxes received by the light receiving unit.

摘要： The optical characteristics of an eye to be tested having a large amount of aberration can be measured accurately. A first illuminating optical system (10) illuminates an eye to be tested (100) with a wide beam by using a light flux from a light source (11). A first light receiving unit (21A) receives reflection light fluxes from the eye to be tested that have been converted into practically at least 17 beams by a first conversion member (22A). A first compensation optical unit (60A), disposed in the first illuminating optical system (10), compensates an illuminating light flux to the eye to be tested (100) for aberration. A second compensation optical unit (60B), disposed in a first light receiving optical system (20A), compensates a reflection light flux from the eye to be tested (100) for aberration. An operation unit determines, based on an output from the first light receiving unit (21A), a compensation amount for canceling out aberration to deform the first and second compensation optical units (60A, 60B) and hence compensate for aberration. In addition, the operation unit determines the optical characteristics of the eye (100), based on optical characteristics based on an output from the first light receiving unit (21A) after compensation, and on compensated optical characteristics.
