（１）被検者に視標を呈示する視標呈示部と、被検者が手に持って片眼の視野を遮蔽する遮眼具と、該遮眼具に設けられ遮蔽されない被検者の測定眼の左右を判別する測定眼判別手段と、前記遮眼具に設けられ前記測定眼判別手段による判別情報を無線通信で送信する送信手段と、該送信された信号を受信する受信手段と、該受信された測定眼の判別情報を出力する出力手段と、を備えることを特徴とする。
（２）（１）の測定眼判別手段は、被検者の顔に向けて波動エネルギを発しその反射を検出する波動エネルギ検出手段によって測定眼を判別することを特徴とする。
（３）（２）の視力測定装置において、前記波動エネルギ検出手段は前記遮眼具の左右に２個所設けられ、前記測定眼判別手段は前記波動エネルギ検出手段の左右での出力の違いに基づいて測定眼の左右を判別することを特徴とする。
（４）（１）の視力測定装置において、前記視標呈示部に呈示された視標に対する被検者の応答を入力する応答入力手段と、入力された応答と呈示視標との正誤を判定して視力値を自動的に決定する視力測定手段とを備え、前記出力手段は測定結果と前記測定眼判別手段による判別情報とを対応させて出力することを特徴とする。
（５）（４）の視力測定装置において、前記応答入力手段は前記遮眼具に設けられた被検者の応答の音声を入力する音声入力手段であり、該音声入力手段により入力された音声を認識する音声認識手段と、測定時に被検者をガイドするための音声を発生する音声発生手段であって前記遮眼具に設けられた音声発生手段と、を備えることを特徴とする。0008
(1) An optotype presenting unit that presents an optotype to the subject, an eye shield that the subject holds in his hand to block the visual field of one eye, and a subject that is provided on the eye shield and is not shielded. A measuring eye discriminating means for discriminating the left and right of the measuring eye, a transmitting means provided in the eye shield for transmitting discrimination information by the measuring eye discriminating means by wireless communication, and a receiving means for receiving the transmitted signal. It is characterized by comprising an output means for outputting the received discrimination information of the measurement eye.
(2) The measuring eye discriminating means of (1) is characterized in that the measuring eye is discriminated by the wave energy detecting means that emits wave energy toward the face of the subject and detects the reflection thereof.
(3) In the visual acuity measuring device of (2), the wave energy detecting means are provided at two places on the left and right of the eye shield, and the measuring eye discriminating means is based on the difference in output between the left and right of the wave energy detecting means. It is characterized in that the left and right of the measurement eye are discriminated from each other.
(4) In the visual acuity measuring device of (1), the response input means for inputting the response of the subject to the optotype presented on the optotype presenting unit, and the correctness of the input response and the presenting optotype are determined. It is provided with a visual acuity measuring means for automatically determining a visual acuity value, and the output means is characterized in that the measurement result and the discrimination information by the measuring eye discriminating means are associated with each other and output.
(5) In the vision measuring device of (4), the response input means is a voice input means for inputting the voice of the response of the subject provided in the eye shield, and the voice input by the voice input means. It is characterized by comprising a voice recognition means for recognizing a voice, and a voice generation means for generating a voice for guiding a subject at the time of measurement, which is provided in the eye shield.
