(1) The right-eye optotype and the left-eye optotype, which are optically placed at a distant distance, are switched and presented on the left and right optotype display windows inside the housing, and are fused into one for both eyes. For the right eye, which is a rotating disk plate in which various optometry objects to be presented to both the left and right eyes are formed on the same surface in the optotype presenting device for observing the fusion, and is presented to the left and right eyes at the same time for fusion observation. A rotating disc plate formed by the optotype and the optotype for the left eye corresponding to the positional relationship of the left and right optotype display windows, and the disc plate is rotated to present the desired optotype to the eye to be inspected. It is characterized by including a rotating means.
(2) In the optotype presenting device of (1), the rotating disc plate is characterized in that the right eye optotype and the left eye optotype are arranged side by side on a circumference different from the rotation center thereof. And.
(3) The right-eye optotype and the left-eye optotype, which are optically placed at a distant distance, are switched and presented in the left and right optotype display windows inside the housing, and are fused into one for both eyes. In the optotype presenting device for observing, a rotating disk plate on which various inspection optotypes to be presented to both the left and right eyes are formed, and a right eye optotype to be presented simultaneously for fusion observation. Rotation in which the optotype background portion surrounding each of the left eye optotypes has the same shape, and the color of the outer periphery of the optotype background portion is substantially the same as the color of the outer periphery of the optotype display window. It is characterized by comprising a disc plate and a rotating means for rotating the disc plate in order to present a desired target to the eye to be inspected.

Claims (3)

The right-eye target and the left-eye target optically placed at a far distance are switchably arranged and presented to the left and right visual target presentation windows inside the housing, and the two eyes are fused and observed In the optotype presenting apparatus as described above, it is a rotating disc plate in which various examination targets presented to the left and right eyes are formed on the same surface, and the optotype for right eye presented simultaneously for left and right for fusion observation.
