For example, when performing the optometry of the right eye ER, the subject blocks the front of the left eye EL with the eye shield 3 and visually recognizes the chart 1 only with the right eye ER.

On the other hand, as shown in FIG. 1, the examiner designates a specific Landolt ring (for example, a Landolt ring having a visual acuity value of 0.1) on the chart 1 with the pointing rod 4 to the subject. Then, the optometry for the subject proceeds.

The pointing rod 4 has, at its tip, an infrared distance signal transmitting section 5 as an optotype signal transmitting section and an infrared transmitting section 6 as a transfer signal transmitting section. A distance signal switch 5a, which is an optotype signal transmission switch operated when actually emitting an infrared distance signal, and a response from the subject (for example, "up", "right", etc., which means the direction in which the Landolt ring is open) An infrared switch 6a, which is a transfer switch operated when a transfer signal is actually issued in response to a voice signal.

The distance measuring sensor 13 measures the distance between the subject who is visually recognizing the Landolt ring and the chart 1, for example, infrared rays from the distance measuring sensor 13 on the back of the eye shield 3 (facing the chart 1). Irradiation is performed on the infrared reflecting member 3a adhered to the surface to be measured, and the reflected light from the infrared reflecting member is received to perform measurement.

The calculation of the visual acuity value by the calculation unit 15 is performed as follows. Based on the visual acuity value when the distance between the examiner and the chart 1 is, for example, 5 meters, if the actual distance that the examiner is looking at a Landolt ring of, for example, 0.1 (based on 5 meters) is 4 meters, The eyesight value at that time is
0.1 * 4/5 = 0.08.

Further, the setting of the relationship between the position of the Landolt's ring on the chart 1 and the visual acuity value (reference visual acuity value of 5 m optometry) is performed as follows.

That is, the setting button 12a of the input unit 12 shown in FIG. 3 is pressed, and visual acuity value data is input from the ten key unit 12b as 0.1. At this time, a value of 0.1 is displayed on the display panel 12c.

Similarly, the position information of each Landolt ring such as 0.2 and 0.3 is transmitted to the receiving unit 11 to set the reference visual acuity value of the 5-meter optometry. When the above-mentioned operation is completed for all Landolt rings, the setting button 12a is pressed. Then, the control unit 18 sorts the position information of each Landolt ring in descending order in the vertical direction, analyzes the information, and stores it in the data table 14.

In this way, an output signal corresponding to the magnitude of the distance between the position of each Landolt ring on the chart 1 indicated by the pointing rod 4 and the receiving unit 11 is output from the receiving unit 11, and based on this output signal. Then, the visual acuity value in this case is obtained by the control unit 18.

FIG. 7 is a table showing the manner in which the visual acuity value is determined based on the test subject's answer (correct or incorrect) and the number of diopters tested. In FIG. 7, the standard threshold value relates to a Landolt ring, and the quasi-standard threshold value relates to a target other than the Landolt ring, which is composed of hiragana and katakana. Then, for example, the number of optotypes of the inspected visual acuity is 5
If the number of correct answers is 3, the visual acuity value at this time is determined as the visual acuity value at the time of the optometry.

According to the first embodiment described above, the examiner instructs one of the Landolt rings with the pointing rod 4, operates the distance signal switch 5a in accordance with the response from the subject, and further operates the infrared signal. By simply operating the switch 6a, the chart-side optometry data transfer means 10, the optometry information storage processing means 2
0, the subject's subjective optometric data is automatically calculated and automatically stored and held, and further, as shown in FIG. 5, the optometric data can be displayed on the display unit 25. Thus, the input operation of the optometry data is small, and the input mistake can be avoided.
