PROBLEM TO BE SOLVED: To provide an eye fatigue measuring apparatus capable of simply measuring eye fatigue.SOLUTION: An eye fatigue measuring apparatus includes: an electrode 110 installed in a nose pad part of glasses which a user wears and coming in contact with a skin on an orbicularis oculi muscle located under the inner corner of an eye of the user an orbicularis oculi muscle potentiometer measuring unit 120 for generating myopotential data that shows a bioelectrical potential generated when the user moves a lower eyelid, using the electrode 110 a blink detection unit 130 for detecting a blink caused by eye fatigue from the myopotential data by assuming that the blink caused by the eye fatigue is performed when the myopotential data shows a larger potential than a prescribed value and a smaller potential than a prescribed value in a prescribed time and a fatigue determination unit 230 for determining a fatigue degree of eyes of the user by calculating a frequency of the detected blink, and specifying the fatigue degree of eyes corresponding to the frequency of the obtained blink based on the relation between the frequency of the blink provided beforehand and the fatigue degree of eyes.COPYRIGHT: (C)2014,JPO&INPIT【課題】簡易に眼疲労を計測することができる眼疲労計測装置を提供する。【解決手段】ユーザが装着する眼鏡の鼻あて部に装着される電極であってユーザの目頭の下に位置する眼輪筋上の皮膚に接触する電極110と、電極110を用いてユーザが下瞼を動かすときに生じる生体電位を示す筋電位データを生成する眼輪筋電位計測部120と、筋電位データが所定の時間内に所定の値より大きい電位と所定の値より小さい電位とを示す場合に眼疲労に起因する瞬きが行われたと扱うことで筋電位データから眼疲労に起因する瞬きを検出する瞬き検出部130と、検出された瞬きの頻度を計算し、得られた瞬きの頻度に対応する眼の疲労度を、予め定められた瞬きの頻度と眼の疲労度との関係に基づいて特定することでユーザの眼の疲労度を判定する疲労度判定部230とを備える。【選択図】図2
