Disclosed is a vision measurement device including: an eyepiece with a lens; an outer tube connected to the eyepiece including a target having a predetermined pattern, the target being movable along an optical axis of the lens with respect to the outer tube; a diopter indicator with an indicating portion and a pointing portion; wherein during the movement of the target with respect to the outer tube along the optical axis of the lens, one of the indicator portion and the pointing portion moves along with the target with respect to the outer tube while the other of the indicator portion and the pointing portion does not move, and when an eye is capable of clearly seeing the predetermined pattern on the target through the eyepiece, the value of the scale indicated by the pointing portion corresponds to the diopter of the eye.

The present invention provides an ophthalmic device capable of minimizing the generation of flare at a lower cost and in a shorter time than in the prior arts when photographing in a state where an optical axis of an examination optical system is deviated from a reference position of a subject eye. The ophthalmic device according to an embodiment of the present invention includes a photographing unit that images a region to be observed of the subject eye through the examination optical system, a first alignment unit that performs alignment on the examination optical system with respect to the subject eye in the optical axis direction and the direction perpendicular to the optical axis direction, an optical system movement unit that moves the examination optical system from a first position aligned by the first alignment unit to a second position which is deviated from the first position at least in the perpendicular direction, and a second alignment unit that determines an alignment position in the optical axis direction of the examination optical system with respect to the subject eye at the second position based on the positional difference between the first position and the second position and moves the examination optical system to the alignment position along the optical axis direction.

To provide a close-up imaging device whereby both imaging of an anterior eye and imaging of an eye ground can easily be performed by attaching the device to a mobile terminal such as a smartphone. The above-described problem is solved by a close-up imaging device (1B) detachably mounted to a mobile terminal (9) equipped with a light source (92) and a camera lens (91) for imaging, comprising a color filter member (97) detachably provided above the light source (92), and a convex lens member (93) detachably provided above the camera lens (91). Imaging, of an anterior eve is performed by removing the color filter member (97) and attaching the convex lens member (93), and observation of an injury of the anterior eye is performed by attaching the color filter member (97) and the convex lens member (93). The dose-up imaging device (1B) may further detachably comprise a slit light forming member that forms light from the light source (92) into slit light by a cylindrical lens, and a tubular member including a convex lens at a tip end thereof.

In an ophthalmology system, an right-eye imaged image is displayed on a display section for presentation to an observer through an optical unit and a reflection member. A left-eye imaged image is also displayed on a display section for presentation to an observer through an optical unit and a reflection member. A separation between the left and right imaged images is made wider than a spacing between the left and right optical units. This enables image presentation with the optical axes for the observer viewing the images intersecting in front so as to cause a convergence angle to arise.
