Abstract: An ophthalmic device may include: a measurement optical system which includes a light-emitting optical system including a light source and a light-receiving optical system including a light receiving element; an arithmetic device configured to calculate an eye refractive power of the subject eye; a beam deflecting member arranged in an optical path of the measurement optical system and configured to deflect beam emitted from the light source, and a driving device configured to drive the beam deflecting member so that the beam emitted from the light source is scanned in a ring shape onto the subject eye. The beam deflecting member may be disposed so that traveling directions of the beam emitted from the light source intersect with each other between the subject eye and the beam deflecting member when the beam deflecting member is driven by the driving device.

Abstract: An ophthalmological device according to one aspect of the present disclosure includes a support structure, an illumination light source, an observation optical system, and a controller. The support structure is configured to support a subject's face. The illumination light source is configured to illuminate a subject's eye. The observation optical system includes an imaging element configured to receive light reflecting off the subject's eye. The controller is configured to acquire, from the imaging element, a first image captured when the illumination light source is on and a second image captured when the illumination light source is off and determine whether the subject's face is placed on the support structure based on a difference between the first image and the second image.

Abstract: A measuring device according to one aspect of the present disclosure projects a measuring light toward a fundus of a subject's eye; receives a reflected light reflected from the fundus; and then measures an eye refractive power of the subject's eye based on a light-receiving signal. Additionally, reliability of a measured value is determined. Specifically, a process, in which the eye refractive power is measured based on the light-receiving signal, is consecutively executed an undetermined number of times until an end condition is satisfied. The measured value of the eye refractive power obtained in every execution of the process is displayed on a display together with information indicating the reliability of the measured value.

Abstract: An ophthalmic device is configured to examine at least two eye characteristics including intraocular pressure, and the ophthalmic device includes: an examination optical system configured to obtain information of a subject's eye when the at least two eye characteristics of the subject's eye are examined; and an examination window configured to switch examinations of the at least two eye characteristics. The examination optical system is arranged outside of the examination window. The examination window is capable of rotating independently of the examination optical system. The examinations of the at least two eye characteristics are switched by rotation of the examination window.

Abstract: A lensmeter includes a light emission portion, a light reception portion, a storage unit, a display unit and a display control unit. The light emission portion emits light so as to radiate the light onto a lens-to-be-inspected. The light reception portion receives the light transmitted through the lens-to-be-inspected to measure an optical characteristic of the lens-to-be-inspected. The storage unit stores a measured value of the optical characteristic of the lens-to-be-inspected. The display unit displays the measured value of the optical characteristic of the lens-to-be-inspected stored in the storage unit. The display control unit causes the display unit to display a target pattern including at least two different colors, and changes the target pattern in accordance with the measured value stored in the storage unit.
