- the display means for the right eye and the display means for the left eye can enter the field of view only when the user shifts the line of sight downward by 20 ° or more.
- the parasympathetic nerves that work thereby allow you to maintain a relaxed state when viewing the image, allowing you to view the image without accumulating fatigue.
- entering the field of view when shifted downward by 20 ° or more here refers to the case where the image enters the field of view when the user shifts his / her line of sight right below from the front, and the case where the image is shifted diagonally downward. And the case where the image enters the field of view. The same applies to other angles.
- the display means for the right eye and the display means for the left eye can be attached to the main body so as to enter the field of view only when the user shifts his / her line of sight downward by 20 ° or more and 70 ° or less. It is difficult to look down at more than 70 °, and if you dare to request it, you will rather cause fatigue.
- the display means for the right eye and the display means for the left eye can be attached to the main body so that the user enters the field of view only when the user shifts his / her line of sight downward by about 45 °. If the angle required to shift the line of sight required to view an image is approximately 45 °, the fatigue of the user is likely to be minimized.
- the optical system provided in the display means for the right eye and the display means for the left eye converts an image displayed on the display into an image of a user. It has a lens that forms an image on the retina of the right or left eye.
- the center axis of the lens for the right eye is aligned with the line of sight of the right eye,
- the center axis of the lens may be substantially coincident with the line of sight of the left eye.
