摘要： A model eye for an eye characteristic measuring device and a calibration method for the model eye. The model eye can have various aberrations and/or power characteristics to be formed by a combination of a refractive-type lens and a phase plate for adding aberration and can be used to confirm the accuracy of wavefront measurement or the like of the eye characteristic measuring device. The model eye includes an anterior eye lens forming a predetermined power to be given to the model eye, a diffusion surface diffusing and reflecting incident light, the diffusion surface being disposed at an image point position corresponding to the predetermined power in relationship to the anterior eye lens, and an aberration adding member giving a predetermined aberration to an area between the anterior eye lens and the diffusion surface. Power and aberration required for the model eye are formed by the anterior eye lens and the phase plate.

摘要： Optical performance in a case where not only higher order aberrations but also lower order aberrations are added, are evaluated, lower order aberration quantities in which for example, a Strehi ratio is large and/or a phase shift is decreased, is calculated, and correction data, such as S, C and A, at that time is obtained, so that a result closer to a subjective value is obtained. An arithmetic part receives measurement data indicating a refractive power distribution of a subject eye and obtains lower order aberrations and higher order aberrations on the basis of the measurement data (S401, S403). The arithmetic part judges whether the higher order aberrations have a specified value or higher (S405). The arithmetic part changes, in a case where the higher order aberrations have the specified values or higher, lower order aberration quantities corresponding to the higher, lower aberrations having the specified values or higher, obtains appropriate correction data suitable for the subject eye (S407 to S417), and obtains the correction data (S419).

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.
