Document Type and Number:

Japanese Patent JP3971405

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a pupil response confirmation device allowing a subject to confirm the response of the subject's pupils by himself/herself while controlling the cost increase, and a fatigue recovery facilitating device equipped with the same.
SOLUTION: The subject can relieve the strained ciliary muscle by observing an image film projected by a repeatedly blinking LED light source. The LED light source is temporarily put out after the blinking operation of the LED light source is repeated for a prescribed period of time, and after that, the blinking operation of the LED light source is started again. If the subject receives the optical blinking stimulation from the LED light source on the eyes, the pupils of the subject's eyes are made to repeat the states of the mydriasis and miosis, and the subject can visually confirm both states by himself/herself using a half mirror.
