Title
(EN) EYE-FATIGUE EXAMINING DEVICE AND EYE-FATIGUE EXAMINING METHOD
(FR) DISPOSITIF D’EXAMEN DE FATIGUE OCULAIRE ET PROCÉDÉ D’EXAMEN DE FATIGUE OCULAIRE
(JA) 眼疲労検査装置及び眼疲労検査方法
Abstract
(EN) Provided is an eye-fatigue examining device and an eye-fatigue examining method with which it is possible to examine eye fatigue of eyes to be examined regardless of the age of a patient. The eye-fatigue examining device is provided with: a light-level difference adjusting unit that increases a light-level difference between beams that enter left and right eyes to be examined, respectively; a sight-direction detecting unit that detects sight directions of the eyes to be examined while the light-level difference adjusting unit is increasing the light-level difference; and a light-level difference determining unit that determines, on the basis of the detection results of the sight-direction detecting unit, a specific light-level difference at which changes in the sight directions occur in association with the increase in the light-level difference.
(FR) L’invention concerne un dispositif d’examen de fatigue oculaire et un procédé d’examen de fatigue oculaire grâce auquel il est possible d’examiner la fatigue oculaire d’yeux à examiner indépendamment de l’âge d’un patient. Le dispositif d’examen de fatigue oculaire comporte : une unité de réglage de différence de niveaux de lumière qui augmente une différence de niveaux de lumière entre des faisceaux qui entrent dans les yeux gauche et droit qui doivent être examinés, respectivement ; une unité de détection de direction du regard qui détecte les directions du regard des yeux qui doivent être examinés tandis que l’unité de réglage de différence de niveau de lumière augmente la différence de niveaux de lumière ; et une unité de détermination de différence de niveaux de lumière qui détermine, sur la base des résultats de détection de l’unité de détection de direction du regard, une différence spécifique de niveaux de lumière à laquelle des changements des directions de regard se produisent en association avec l’augmentation de la différence de niveaux de lumière.
(JA) 患者の年齢に関係なく被検眼の眼疲労を検査することができる眼疲労検査装置及び眼疲労検査方法を提供する。左右の被検眼にそれぞれ入射する光の光量差を拡大する光量差調整部と、光量差調整部が光量差を拡大している間、被検眼の視線方向を検出する視線方向検出部と、視線方向検出部の検出結果に基づき、光量差の拡大に伴う視線方向の変化が発生する特定の光量差を決定する光量差決定部と、を備えるようにする。
