An eye refractive power measuring device, comprising: a light projector configured to project a measuring light toward a fundus of a subject's eye; a light receiver configured to receive a reflected light that is reflected from the fundus; a detector configured to detect a position of the subject's eye; an inputter configured to input a command from an operator; and a controller, wherein the controller is configured to start a consecutive measurement process of a refractive power of the subject's eye without automatic fogging in response to input of a start command through the inputter, the consecutive measurement process including: consecutively executing (S320, S330) a process (S410, S430) that measures the eye refractive power of the subject's eye based on a light-receiving signal from the light receiver without automatic fogging until an end of the consecutive measurement process; determining reliability of a measured value of the eye refractive power in every execution of the process; and displaying (S450, S460, S470, S480), in every execution of the process, the measured value on a display together with information indicating the reliability, wherein the reliability is determined based on at least one of the position of the subject's eye that is detected by the detector, or spatial distribution of the reflected light, and wherein the controller ends the consecutive measurement process in response to input of an end command through the inputter or in response to the measured value having the reliability equal to or greater than standard reliability being obtained a specific number of times. a light projector configured to project a measuring light toward a fundus of a subject's eye; a light receiver configured to receive a reflected light that is reflected from the fundus; a detector configured to detect a position of the subject's eye; an inputter configured to input a command from an operator; and a controller, wherein the controller is configured to start a consecutive measurement process of a refractive power of the subject's eye without automatic fogging in response to input of a start command through the inputter, the consecutive measurement process including: consecutively executing (S320, S330) a process (S410, S430) that measures the eye refractive power of the subject's eye based on a light-receiving signal from the light receiver without automatic fogging until an end of the consecutive measurement process; determining reliability of a measured value of the eye refractive power in every execution of the process; and displaying (S450, S460, S470, S480), in every execution of the process, the measured value on a display together with information indicating the reliability, consecutively executing (S320, S330) a process (S410, S430) that measures the eye refractive power of the subject's eye based on a light-receiving signal from the light receiver without automatic fogging until an end of the consecutive measurement process; determining reliability of a measured value of the eye refractive power in every execution of the process; and displaying (S450, S460, S470, S480), in every execution of the process, the measured value on a display together with information indicating the reliability, wherein the reliability is determined based on at least one of the position of the subject's eye that is detected by the detector, or spatial distribution of the reflected light, and wherein the controller ends the consecutive measurement process in response to input of an end command through the inputter or in response to the measured value having the reliability equal to or greater than standard reliability being obtained a specific number of times.
