摘要： An eye characteristic measuring apparatus can effectively and properly measure and display wavefront aberration of an eye regardless of the eye state. A first illumination optical system (200A) illuminates a small area on a retina of the eye by a first light flux from a first light source unit (100). A first reception light optical system (300A) leads a part of light flux reflected from the retina (61) to a first light reception unit (510) via a first conversion member (400) for converting the reflected light flux into at least 17 beams. A measurement data judgment unit, for example, judges whether the measurement data is appropriate for calculating the wavefront aberration according to a first signal from the first light reception unit (510). For example, when the measurement data judgment unit judges that the measurement data is not appropriate, a first correction unit causes to display a check correction screen which will be detailed later and corrects the data into appropriate measurement data. Furthermore, according to the measurement data judged to be appropriate or the measurement data which has been corrected by the first correction unit (603), a calculation unit calculates the wavefront aberration of the eye (60) as optical characteristic. Moreover, a measurement result judgement unit for example, judges whether the wavefront aberration calculated by the calculation unit is appropriate. Moreover, for example, when the measurement result judgment unit judges that the measurement result is not appropriate, a second correction unit (607) causes to display the check correction screen and correct the data into appropriate measurement data.

摘要： The position of an object surface is detected with an error reduced on a reflectance boundary surface. A first light source (100) emits the luminous flux of the first wavelength. A first illumination optical system (200A) illuminates a small area on a retina (61) to be examined by the first luminous flux from the first light source (100). A first reception optical system (300A) guides a part of the luminous flux which is reflected by and returning from the retina (61) to be examined to a first light reception part (510) via a first conversion member (400) for converting the reflected luminous flux into at least 17 beams. A second light source (110) emits the luminous flux of the second wavelength. A second illumination optical system (200B) illuminates a predetermined area on the retina (61) to be examined by the second luminous flux from the second light source (110). A second reception optical system (300B) guides the second luminous flux reflected by and returning from the retina (61) to a second light reception part (520). A display part checks at which position on the fundus oculi (61) of the eye (60) the luminous flux for measurement is converged or fixed, and the position of convergence and the position of measurement are changed by using a drive unit to move a fixation mark or the irradiation position of the irradiation light for Hartmann measurement.

摘要： It is possible to estimate optical characteristic according to a pupil diameter in daily life of an examinee, correction data near to the optimal prescription value, eyesight, and sensitivity. A calculation section receives measurement data indicating refractive power distribution of an eye to be examined and pupil data on the eye and calculates lower order and higher order aberrations according to the measurement data and the pupil data (S101 to 105). For example, a pupil edge is detected from the anterior ocular segment image and a pupil diameter is calculated. By using this pupil diameter, lower order and higher order aberrations are calculated. According to the lower order and higher order aberrations obtained, the calculation section performs simulation of a retina image by using high contrast or low contrast target and estimates the eyesight by comparing the result to a template and/or obtains sensitivity (S107). Alternatively, according to the lower order and the higher order aberraations obtained, the calculation section calculates an evaluation parameter indicating the quality of visibility by the eye to be examined such as the Strehl ratio, the phase shift (PTF), and the visibility by comparison of the retina image simulation with the template. According to the evaluation parameter calculated, the calculation section changes the lower order aberration amount so as to calculate appropriate correction data for the eye to be examined (S107). The calculation section outputs data such as the eyesight, sensitivity, correction data, and the simulation result to a memory or a display section (S109).

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： The low-order aberration leading to better visual acuity is calculated from the results of measurement of an eye characteristic by an eye characteristic measuring instrument that can measure up to the high-order aberration, and data on a correction factor is collected, thereby obtaining a result more approximate to the subjective value. According to at least measurement data representing the wave aberration of the eye being examined (S401, S403), an image data creating unit creates optotype retina image data by conducting simulation of the visual acuity of an optotype (S405), considering the correction factor for refraction correction. A correction factor setting unit sets a correction factor to be given to the image data creating unit (S417). A judging unit judges from the correction opotype retina image data corrected by the correction factor whether or not an adequate correction factor is set (S407 to S421). The correction factor setting unit sets a correction factor on the basis of the results of judgment by the judging unit, and changes the correction factor until the judging unit judge that the correction factor is adequate.

摘要： A first illuminating optical system illuminates an eye with a wide beam. A first light receiving unit receives reflection light fluxes from the eye that have been converted into at least 17 beams by a first conversion member. A first compensation optical unit, disposed in the first illuminating optical system, compensates an illuminating light flux to the eye for aberration. A second compensation optical unit, disposed in a first light receiving optical system, compensates a reflection light flux from the eye for aberration. An operation unit determines, based on an output from the first light receiving unit, a compensation amount for cancelling out aberration to deform the first and second compensation optical units and compensate for aberration. The operation unit determines the optical characteristics of the eye, based on an output from the first light receiving unit after compensation, and on compensated optical characteristics.
