However, spectacles that partially block the wearer's field of vision and enclosures that surround the eyes are not designed for those who wear spectacles on a daily basis.
Therefore, there is a problem that it is difficult or impossible for a person who wears eyeglasses to use it because it interferes with parts such as bridges and temples constituting general eyeglasses.

For those who routinely wear prescription eyeglasses and blue light countermeasure eyeglasses for personal computer work, which are widely used in general, this problem is a major obstacle for the purpose of blocking a part of the field of vision.
In addition, prescription eyeglasses are sized to suit the individual, so they are designed to fit the heads of the majority of people, with the exception of some protective equipment intended for use by eyeglass wearers. It is difficult to use eyeglass-type items according to the purpose because they may interfere with the eyeglasses or come off the eyeglasses.
Specifically, if it is used forcibly, there are problems that the temporal region and ears are compressed by wearing it for a long time, the glasses may be damaged due to interference, or the glasses cannot be worn.

The present invention was made based on the above circumstances.
The object of the present invention is to block the disturbance of the visual field in the act of viewing and unnecessary visual information, regardless of the shape of various glasses that varies from person to person, and does not interfere with the glasses even if the glasses are still worn. It is to provide a method of adjusting the shielding range of the visual field by making the angle of the shielding plate variable by a shielding plate that blocks a part of the visual field and a joint portion that can be attached and detached.

The problem to be solved by the present invention is to determine the position of the detachable part for attaching a shielding plate that blocks a part of the field of view without interfering with the glasses while wearing the glasses, regardless of the shape of the various glasses. It is characterized by having a mechanism for adjusting and a mechanism for changing the angle of the shielding plate in order to arbitrarily change the range of blocking the field of view.

FIG. 1 shows an example of the appearance of a field-of-view shielding plate that can be adjusted according to the size of eyeglasses. 5 is a joint on the upper surface, 6 is a shield plate on the side surface where the angle can be changed, 7 is a shield plate on the upper surface where the angle can be changed, and 8 is a part to be attached to the bridge of the glasses.

FIG. 2 is a front view for showing the form of the field of view shielding plate that can be adjusted according to the size of the glasses, and FIG. 9 shows a portion to be attached to the temple of the glasses. As a mounting method, there are pinching and support by its own weight.
In FIG. 2, by sliding 3, the position of 9 can be adjusted in the width direction along with 2, 4, and 6 depending on the size of the individual's glasses.
With this mechanism, a shielding plate that partially blocks the field of view can be attached and detached even for glasses having individual differences in size by supporting three points consisting of 8 and 9 having an adjusted width direction.
By this method of putting on and taking off, the person who wears the spectacles on a daily basis can adjust the range of the field of view arbitrarily shielded by the wearer without removing the spectacles and without interfering with the spectacles.

FIG. 3 shows an example of the appearance of a movable visual field shielding plate that can be adjusted according to the size of the glasses.
The joint 4 allows the 6 to be tilted to any angle in the left-right direction, and the joint 5 allows the 7 to be tilted to any vertical angle, thus providing a portion of the unwanted field of view. Cut off.

The view shield that can be adjusted according to the size of the glasses of the present invention is attached by adjusting the position of the mounting part according to the width of the temple of the glasses, so that the glasses can be worn without interfering with general glasses. It can be used as it is.
According to the structure of the present invention, it is possible to adjust the range of the visual field that shields the disturbance of the visual field and unnecessary visual information at the wearer's discretion while wearing the spectacles without interfering with the general spectacles. ..

FIG. 1 shows an example of the appearance of a view shielding plate that can be adjusted according to the size of the glasses. (Example 1) FIG. 2 is a front view for showing the form of the view shielding plate that can be adjusted according to the size of the glasses. FIG. 3 shows an example of an appearance in which the field of view is blocked after adjusting according to the size of the glasses. (Example 2)

In the view shielding plate of this embodiment shown in FIG. 1, the upper surface shielding plate 1 is connected to a shielding plate 7 that is movable around a joint 5, and the upper surface shielding plate 1 is further connected to a side shielding plate 2 by a slide mechanism 3. Has been done.
Further, the side shielding plate 2 is connected to a shielding plate 6 that is movable around the joint 4, and realizes a method for a person wearing glasses to arbitrarily adjust the degree of blocking the view in the upper surface direction and the side surface direction.

FIG. 1 is an external view of an embodiment of the device of the present invention, and FIGS. 1 to 8 are the same as those in FIG.

FIG. 2 is a front view showing the form of the device of the present invention, and 2 to 4 and 6 and 8 are the same as those in FIG.

In FIG. 2, the shielding plate of the present invention can be attached and detached by fixing or holding the bridge of the glasses at 8 and the temples of the glasses at 9 on the left and right, which can be adjusted in position, at a total of 3 places.

Since the form of attaching and detaching to and from the glasses is adopted in this way, the wearer of the glasses can use the shielding plate while wearing the glasses without interfering with the glasses.
Therefore, the wearer of the spectacles can always block a part of the field of view in the side surface direction and the upper surface direction while always ensuring the field of view in the front direction.
Further, the angles of the upper surface shielding plate and the side surface shielding plate can be arbitrarily changed around the joint as an axis, and there is an effect that the disturbance blocking range in the user's field of view can be arbitrarily changed.

The embodiment of FIG. 3 is an example of an appearance in which the angle of the upper surface shielding plate and the side surface shielding plate is changed around the joint to narrow the range of the front view.
In sitting situations such as desk work, the field of view is from the front to the bottom, focusing on objects such as computer screens and documents on the desk.
Under these circumstances, the ability to block a portion of the field of vision that is not the subject of viewing and may be affected by disturbances is of great help to spectacle wearers to improve workability and maintain concentration.

It can also be applied to protect the eyes from the sunlight incident from the side and overhead and the light of the lighting device in computer work mainly for desk work and desktop work such as reading and studying.

Also, in desk work, partitions for the purpose of securing a space that eliminates disturbance of the field of vision in the work environment, such as a personal booth or a tsuitate installed on a desk, are practically used, but such a space can always be used. Is not always.
Even in such a case, it can be applied to applications where the same effect can be obtained regardless of the location by adjusting the range of blocking a part of the field of view centering on the object of the act of viewing.
