本发明之目的为提供一种可抑制成本提高，并且可使被实验者自己确认其瞳孔反应之瞳孔反应确认设备，及具有该瞳孔反应确认设备之恢复疲劳促进设备。该瞳孔反应确认设备包含有作为必须构造之反射部与刺激附加部。其中，反射部系构成为具有配置于与被实验者视线交叉的方向上之光学反射面，且于该光学反射面上形成被实验者瞳孔的影像者。而刺激附加部系对被实验者附加用以诱发瞳孔反应之刺激者。又，亦可使用给予被实验者的眼睛光刺激之LED光源或电灯泡、闪光灯等之光源来作为具体的刺激附加部。

A pupil reaction ascertaining device for enabling the subject for oneself to ascertain the pupil reaction while suppressing the increase of the cost and a fatigue recovery promoting device having the pupil reaction ascertaining device are disclosed. The pupil reaction ascertaining device comprises, as essential constituents, a reflecting section and a stimulus applying section. The reflecting section includes an optical reflecting surface provided perpendicularly to the line of vision of the subject. On the optical reflecting surface, an image concerning the pupil of the subject is formed. The stimulus applying section applies stimulus to induce a pupil reaction to the subject. Specific examples of the stimulus applying section include light sources for applying optical stimulus to the eye of the subject, such as an LED light source, an electric light bulb, and a strobe light.
