That is, when the right-eye display means or the left-eye display means, which is an integrated unit, is held by the right-eye holding means or the left-eye holding means, the right-eye display means: When the person wears the main body on the head and shifts the line of sight of the right eye downward by a predetermined angle of 20 ° or more from the front, the image enters the view of the right eye, and is displayed for the left eye.
- the means is arranged such that, when the user wears the main body on the head and shifts the line of sight of the left eye downward by a predetermined angle of 20 ° or more from the front, the image enters the field of view of the left eye. Can be.
- the display means for the right eye and the display means for the left eye enter the field of view of the user only when the user shifts his / her line of sight downward by 20 ° or more. This is to prevent the right-eye display means or the left-eye display means from entering the field of view when facing the front, preventing the field of view from the outside world from being secured. It is an ingenuity that takes into account the fact that the user's fatigue in such cases is reduced. The reason that the user's fatigue when viewing images is reduced by doing this is as follows.
- 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 act on it can maintain a relaxed state when viewing images, and can view images 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 is as described above. Is provided with a lens for forming an image displayed on the retina of the user's 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, and the lens for the left eye.
