After the eye 81 absorbs a portion of the wavelength of the first reflected light 312, the second reflected light 313 is reflected from the second light entrance 22 and is refracted. A second refracting ray 314 is emitted from the third ray exit 25; the first lens 41 is located between the light source 30 and the cymbal 20, and the light 31 emitted by the light source 30 is self-contained via the first lens 41. The first light entrance 21 enters the cymbal 20; the second lens 42 is located between the eye 81 of the subject and the cymbal 20, and the first reflected light 312 is emitted from the second light exit 24, The second lens 42 enters the eye 81 of the subject.

The above is the main components of the creation embodiment and its configuration description. As for the use and efficacy of the present embodiment, the first thing to know is that since the human eye is different in wavelength or absorption under different states or diseases, the comparative analysis of the light passes through the front of the eye and the light. The difference in the spectrum after reflection through the eye can be used as a control of the state of the eye. For example, when a person's eyes are fatigued, a large amount of blood will be congested, resulting in more red blood cells in the eyeball. When the light passes through the eyes, the long-wavelength light that is closer to the red light will be reflected more. Therefore, when the second refracted ray 313 and the first refracted ray 312 are compared, a long-wavelength ray is found, and when it is reflected more after passing through the eye, it can be judged that the subject's eyes may be in a fatigue state. It is caused by different physical causes For the clinical phenomenon of the corresponding eyes, please refer to Table 1.

Please refer to FIG. 3 and FIG. 4 together with FIG. 1 and FIG. 2 for explaining how the light 31 emitted by the light source 30 is divided into a first refracted ray 311 and a second refracted ray 314. . As shown in the figure, the light 31 emitted from the light source 30 enters the crucible 20 from the first light entrance 21, and is refracted and reflected into a first refracted ray 311 and a first reflected ray 312. The first refracted ray 311 is emitted from the first ray exit 23, and the first reflected ray 312 is emitted from the second ray exit 24 and enters the eye 81 of the subject, and the eye 81 of the subject absorbs the After a portion of the first reflected light ray 312 reflects a second reflected light 313, the second reflected light 313 enters the crucible 20 from the second light entrance 22 and is refracted to become a second refraction. Light ray 314 is emitted from the third light exit 25.
