Description

The present invention relates to eyeglasses worn by one-eyed people.

People who have extremely poor vision in one eye or have lost vision in one eye and need to see with only the other eye (one-eyed people, monocular people) are people who see things with both eyes. The field of view becomes narrower in comparison.

It would be highly desirable to have glasses that could widen the visual field for one-eyed people by wearing them, similar to normal eyeglasses for correcting visual acuity. Until now, reading glasses have been devised as glasses for people with one eye (for example, see Patent Document 1), but these reading glasses are related to bifocal glasses, and cannot widen the visual field of people with one eye. .

Utility Model Publication No. 61-128620

The reality is that there are no glasses that can be worn (weared) in the manner described above to widen the field of view of a one-eyed person. Considering the ease of use for one-eyed people, it is preferable to use eyeglasses that are equivalent to normal eyeglasses for correcting visual acuity, and the development of such eyeglasses for one-eyed people is eagerly awaited.

An object of the present invention is to provide glasses for one-eyed persons that can widen the visual field of one-eyed persons.

The present invention includes an eyeglass frame, a first lens attached to either the left or right side of the eyeglass frame, and a first lens located on a nose pad side with respect to the first lens , and arranged side by side with the first lens. a wide-angle lens attached to the eyeglass frame, the wide-angle lens having an objective lens, an eyepiece lens, and a cylindrical body housing the objective lens and the eyepiece lens, When viewing glasses for one-eyed people, the field of view can be made wider than when not using glasses for one-eyed people, and a part of the barrel of the wide-angle lens functions as a nose pad. These are glasses for use.

The spectacles for one-eyed persons according to the present invention are characterized in that the spectacle frame is a rimless frame, and the first lens and the bridge of the spectacle frame are fixed to the wide-angle lens.

The glasses for one-eyed persons of the present invention further include a second lens attached to the side opposite to the first lens among the left and right sides of the eyeglass frame, and the second lens is a dummy lens, and when viewed from the front, the second lens is a dummy lens. The outer periphery formed by the first lens and the wide-angle lens has the same shape and size as the outer periphery of the second lens.

According to the present invention, it is possible to provide glasses for a one-eyed person that can widen the visual field of a one-eyed person.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of spectacles 1 for one-eyed persons according to a first embodiment of the present invention, viewed diagonally from above on the front side. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of glasses 1 for one-eyed persons according to a first embodiment of the present invention, viewed diagonally from above on the back side. It is a figure for explaining the composition of wide-angle lens 41 which is a modification of glasses 1 for one-eyed persons of a 1st embodiment of the present invention. FIG. 2 is a perspective view of spectacles 2 for one-eyed persons according to a second embodiment of the present invention, viewed obliquely from above on the front side. FIG. 3 is a perspective view of glasses 3 for one-eyed persons according to a third embodiment of the present invention, as viewed obliquely from above on the front side. It is a perspective view of glasses 3 for one-eyed persons according to a third embodiment of the present invention, viewed diagonally from above on the back side.

FIG. 1 is a perspective view of eyeglasses 1 for one-eyed people according to the first embodiment of the present invention viewed diagonally from above on the front side, and FIG. It is a perspective view seen from diagonally above. The X direction, Y direction, and Z direction described in the drawings (including other embodiments) and the specification represent the X-axis direction, Y-axis direction, and Z-axis direction, respectively, of a three-dimensional orthogonal coordinate system. In this embodiment, it is assumed that a one-eyed person who wears glasses 1 for one-eyed persons has extremely reduced visual acuity in the right eye or has lost visual acuity in the right eye when viewed from the front. This point also applies to other embodiments.

Eyeglasses 1 for one-eyed persons according to the first embodiment of the present invention are glasses that widen the field of view for one-eyed persons when worn (wearing), and include an eyeglass frame 10 and a pair of eyeglass frames 10 that are attached to the left side when the eyeglass frame 10 is viewed from the front. A wide-angle lens 40 is attached to the eyeglass frame 10 side by side with the first lens 31, and a second lens 51 is attached to the right side of the eyeglass frame 10 when viewed from the front.

The eyeglass frame 10 has rims 13 and 14 for holding lenses on the left and right sides of the front, and the left and right rims 13 and 14 are connected by a bridge 15, like ordinary eyeglasses. The nose pad 18 on the right side when viewed from the front is provided integrally with the rim 14 on the right side. On the other hand, the left nose pad 17 when viewed from the front is provided integrally with the wide-angle lens 40. A temple 19 is attached to the left and right rims 13 and 14 via a hinge 21.

As the first lens 31, a lens is selected depending on the purpose and use. For example, if a person with one eye has myopia, a prescription lens will be used to correct the short-sightedness; if there is no need to correct vision, a non-prescription lens may be used. In addition, UV cut lenses, blue light cut lenses, etc. can be used like normal glasses.

The first lens 31 has a size and shape that fits into the rim 13 without any gaps, except for the right side when viewed from the front. The width of the first lens 31 (in the Y direction) is about 70 to 90% of the width of the rim 13 (in the Y direction). Therefore, when the first lens 31 is attached to the rim 13, the right side of the rim 13 becomes vacant when viewed from the front, and the wide-angle lens 40 is attached to fill this area. The right side surface 33 of the first lens 31 is a straight line parallel to the X direction when viewed from the front (see FIG. 3).

The wide-angle lens 40 includes an objective lens (objective side lens) 48 and an eyepiece lens (eyepiece side lens) 49 attached to a cylindrical body 43, like a conventional wide-angle lens. Normally, wide-angle lenses are classified into wide-angle, standard, and telephoto lenses, and also include fisheye lenses and ultra-wide-angle lenses, but the same applies to the wide-angle lens 40 used here, and you can use an appropriate selection from these. . Here, the objective lens 48 and the eyepiece lens 49 may each include a plurality of lens groups, and the wide-angle lens 40 may further include other lenses and other lens groups. The focal length of the wide-angle lens 40 is set in accordance with the user's visual acuity. Further, the wide-angle lens 40 can be one that has a function of cutting UV (ultraviolet rays) or blue light.

The function of the wide-angle lens 40 is basically the same as a conventional wide-angle lens, but its shape is different from that of a conventional general wide-angle lens. The cylindrical body 43 has a substantially arcuate shape when viewed from the front and from the rear. More specifically, the front part (objective lens 48 side) of the cylinder 43 has a shape and height such that the right side fits tightly onto the right side (bridge 15 side) of the rim 13 when viewed from the front. The width of the front part of the cylinder 43 (in the Y direction) is approximately 10 to 30% of the width (in the Y direction) of the rim 13, and the left side of the cylinder 43 forms a straight line parallel to the X direction when viewed from the front. There is. The back surface of the cylinder 43 (on the eyepiece 49 side) has a similar shape to the front surface of the cylinder 43, and its size is smaller than that of the front surface.

The thickness of the cylindrical body 43 (in the Z direction) is such that when the glasses 1 for one-eyed persons are worn, the back surface does not come into contact with the face and eyes of the one-eyed person. If it is necessary to increase the thickness of the barrel 43 (in the Z direction) in terms of focal length, etc., adjust the positions of the nose pads 17 and 18 so that the back of the barrel 43 is closer to the face and eyes of the one-eyed person. Try not to come into contact with it.

The objective lens 48 attached to the front side of the barrel 43 and the eyepiece lens 49 attached to the back side of the barrel 43 are shaped in a front view so as to match the shape of the barrel 43 when viewed from the front and from the rear, respectively. The right side is curved like the bridge 15 side of the rim 13, and the left side is a straight line parallel to the X direction.

The first lens 31 and the wide-angle lens 40 are large enough to fit into the rim 13 without any gap when the right side surface 33 of the first lens 31 and the front left side surface 44 of the wide-angle lens 40 are butted together when viewed from the front. It has become. In this embodiment, the wide-angle lens 40 is bonded to the front right side of the rim 13 so that its front surface is flush with the rim 13. The first lens 31 is attached to the rim 13 so that the right side surface 33 of the first lens 31 is in contact with the front left side surface 44 of the wide-angle lens 40 when viewed from the front.

In general eyeglasses, nose pads are provided on the left and right rims, or nose pads are attached to the left and right rims, but in the glasses 1 for one-eyed people of this embodiment, the nose pad 18 is attached to the rim 14. However, the rim 13 is not provided with a nose pad. Instead, a nose pad 17 on the left side when viewed from the front is provided on the cylindrical body 43 of the wide-angle lens 41. In this embodiment, the nose pad 17 is integrated with the cylindrical body 43.

The left nose pad may be provided on the rim 13 like the right nose pad 18, but by providing the nose pad 17 on the cylindrical body 43, the length of the cylindrical body 43 is reduced compared to when the nose pad 17 is provided on the rim 13. It can be made larger (wider). It is preferable to make the cylindrical body 43 large (wide) because this leads to an enlarged field of view.

The second lens 51 is a dummy lens and fits into the rim 14 without any gaps. The reason why a dummy lens is used as the second lens 51 is because, in the case of a one-eyed person, the visual acuity of the right eye is extremely reduced or the visual acuity of the right eye is lost. The second lens 51 preferably has the same appearance as the first lens or a similar one.

In the glasses 1 for one-eyed persons of this embodiment, the left and right rims 13 and 14 have the same shape and size. Therefore, by fitting the second lens 51 to the right rim 14, the left and right balance is improved and the appearance is good. Furthermore, if the weight of the second lens 51 is made equal to the total weight of the first lens 31 and the wide-angle lens 40, the left and right balance will be better when the glasses 1 for one-eyed persons are worn, making it easier to wear them.

The spectacles 1 for one-eyed persons can be worn and used in the same way as ordinary spectacles. The spectacles 1 for one-eyed persons have a wide field of vision because they are provided with a wide-angle lens 40 near the nose.

When you see things with one eye, your field of vision becomes narrower than when you see things with both eyes. Although it is possible to widen the field of view by using the glasses 1 for one-eyed persons of the first embodiment, the second lens 51 may be removed in order to further expand the field of view. The second lens is basically for improving appearance, so there is no functional problem even if it is not provided. Further, in the glasses 1 for one-eyed persons according to the first embodiment, the shape and size of the left and right rims are the same, but the shape and size of the left and right rims may be different in order to further expand the field of view.

FIG. 3 is a diagram for explaining the configuration of a wide-angle lens 41 that is a modification of the glasses 1 for one-eyed persons according to the first embodiment of the present invention. Components that are the same as those of the glasses 1 for one-eyed persons according to the first embodiment shown in FIGS. 1 and 2 are designated by the same reference numerals, and the description thereof will be omitted.

In the glasses 1 for one-eyed persons shown in FIGS. 1 and 2, the wide-angle lens 40 is fitted into the rim 13 and bonded, but the wide-angle lens 41 shown in FIG. 3 is fitted into the groove of the rim 13 and fixed without being glued. Is possible. The wide-angle lens 41 includes a protrusion 45 on the outer periphery of the front surface of the cylindrical body 43, excluding the left side surface 44, which fits into the groove of the rim 13. By fitting this protrusion 45 into the groove of the rim 13, it can be fixed to the rim 13 in the same way as the first lens 31.

Furthermore, a groove 46 into which the right side surface 33 of the first lens 31 fits is provided on the front left side surface 44 of the cylindrical body 43 of the wide-angle lens 41 . The outer peripheral edge of the first lens 31 is fitted into the groove of the rim 13 and the groove 46 provided in the cylindrical body 43 and is fixed.

If the wide-angle lens 41 and first lens 31 shown in FIG. 3 are used, they can be firmly fixed by fitting them into the rim 13 in the same way as conventional eyeglasses, so existing eyeglass frames can be used. Glasses 1 for one-eyed persons can be easily manufactured.

FIG. 4 is a perspective view of spectacles 2 for one-eyed persons according to a second embodiment of the present invention, viewed diagonally from above on the front side. Components that are the same as those of the glasses 1 for one-eyed persons according to the first embodiment shown in FIGS. 1 to 3 are designated by the same reference numerals, and description thereof will be omitted.

Glasses 2 for one-eyed persons according to the second embodiment have the same basic configuration as glasses 1 for one-eyed persons according to the first embodiment, but differ from glasses 1 for one-eyed persons in the structure of the rim 13 on the left side when viewed from the front. In the glasses 1 for people with one eye according to the first embodiment, the wide-angle lens 40 is fitted into the rim 13 and bonded, but in the glasses 2 for people with one eye according to the second embodiment, the cylindrical body 43 of the wide-angle lens 40 is attached to the rim 13. It is a part of it.

Specifically, the rim 13 into which the first lens 31 fits is provided on the left side surface 44 of the cylindrical body 43 when viewed from the front. Therefore, the bridge 15 connecting the left and right rims is connected to the cylindrical body 43 of the wide-angle lens 40. A concave groove 46 (see FIG. 2) into which the right side surface 33 of the first lens 31 shown in FIG. 3 fits is provided on the left side surface 44 of the cylindrical body 43.

Since the eyeglass frame 10 of the eyeglasses 1 for one-eyed persons according to the first embodiment has the same configuration and structure as general eyeglasses, the eyeglasses 1 for one-eyed persons can be manufactured using an existing eyeglass frame. As a result, the glasses 1 for one-eyed persons can be manufactured easily and inexpensively. Although the glasses 2 for one-eyed people according to the second embodiment cannot structurally use existing eyeglass frames as they are, the wide-angle lens 40 can be made larger than the glasses 1 for one-eyed people according to the first embodiment. can. Therefore, the glasses 2 for people with one eye have the advantage of being able to provide a wider field of vision than the glasses 1 for people with one eye.

Further, in the glasses 2 for one-eyed persons, since the wide-angle lens 40 is integrated with the glasses frame 11, the wide-angle lens 40 can be completely prevented from falling off from the glasses frame 11. Safety is more important for eyeglasses for people with one eye than for conventional general glasses, and glasses 2 for people with one eye that completely prevent the wide-angle lens 40 from falling off are preferable.

FIG. 5 is a perspective view of the glasses 3 for one-eyed people according to the third embodiment of the present invention, viewed diagonally from above on the front side, and FIG. It is a perspective view seen from diagonally above. Components that are the same as those of the glasses 1 for one-eyed persons according to the first embodiment shown in FIGS. 1 to 3 are designated by the same reference numerals, and description thereof will be omitted.

Glasses 3 for one-eyed persons according to the third embodiment have the same basic configuration as glasses 1 for one-eyed persons according to the first embodiment, but the eyeglass frames 12 are rimless frames, and are so-called rimless glasses. The basic configuration of the wide-angle lens 42 is the same as the wide-angle lens 40 of the glasses 1 for one-eyed persons according to the first embodiment, but the wide-angle lens 42 has a mounting seat 47 for mounting the first lens 31 on the cylindrical body 43. . The first lens 31 is screwed to the mounting seat 47 of the wide-angle lens 42 .

When the first lens 31 is attached to the mounting seat 47 of the wide-angle lens 42, it becomes flush with the front surface of the wide-angle lens 42. The bridge 15 connects one end to the cylindrical body 43 of the wide-angle lens 42 and the other end to the second lens 51.

Since the glasses 3 for one-eyed persons of the third embodiment are rimless frames, they are lighter compared to glasses frames with rims, and since there are no rims, the field of view is wider.

As explained using the first to third embodiments, the glasses for one-eyed people according to the present invention are all equipped with wide-angle lenses, so they can widen the field of view for one-eyed people when used in the same way as regular glasses. . Furthermore, since the width of the wide-angle lens is set to be relatively narrow and is attached to the nose pad side, a wide front field of view can be obtained.

Although the glasses for one-eyed persons according to the present invention have been explained above using the first to third embodiments, the glasses for one-eyed persons according to the present invention are not limited to the above-mentioned embodiments, and the gist thereof remains unchanged. It can be changed and used within the range.

As mentioned above, the preferred embodiments have been described with reference to the drawings, but those skilled in the art will easily assume various changes and modifications within the obvious range after viewing this specification. It is therefore contemplated that such changes and modifications are within the scope of the invention as defined by the claims.
