Description

The present invention relates to spectacles worn by a one-eyed person.

Those who have severely diminished visual acuity in one of the two eyes or have lost the visual acuity in one eye and need to see things with only the other eye (one-eyed, one-eyed) are referred to those who see with both eyes. The field of view is narrower in comparison.

It is highly preferable to have eyeglasses that can be worn to widen the field of vision of the one-eyed person, as in the case of ordinary eyeglasses that correct eyesight. So far, reading glasses have been devised for one-eyed spectacles (see, for example, Patent Document 1), but these reading spectacles relate to bifocal spectacles, and the one-eyed spectacles cannot widen the field of view. ..

Jikkai Sho 61-128620

The reality is that there are no spectacles that can widen the field of view of the one-eyed person by wearing (wearing) as described above. Considering the usability of the one-eyed person, it is preferable to use the same spectacles as the ordinary spectacles for correcting the eyesight, and the development of such one-eyed spectacles is awaited.

An object of the present invention is to provide eyeglasses for a one-eyed person who can widen the field of view of the one-eyed person.

The present invention includes a spectacle frame, a first lens attached to either the left or right side of the spectacle frame, and a wide-angle lens attached to the spectacle frame so as to be side by side with the first lens. The wide-angle lens is a pair of eyeglasses for a spectacled person, characterized in that it is located on the nose pad side with respect to the first lens.

In the spectacles for spectacles of the present invention, the wide-angle lens has an objective lens, an eyepiece, and a cylinder for accommodating the objective lens and the eyepiece, and a part of the cylinder of the wide-angle lens is formed. It is characterized by functioning as a nose pad.

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

The spectacles for spectacles of the present invention further have a second lens attached to the left and right sides of the spectacle frame on the side opposite to the first lens, and the second lens is a dummy lens in front view. The outer peripheral edge formed by the first lens and the wide-angle lens is characterized by having the same shape and the same size as the outer peripheral edge of the second lens.

According to the present invention, it is possible to provide eyeglasses for a one-eyed person who can widen the field of view of the one-eyed person.

It is a perspective view which looked at the eyeglass 1 for one-eyed person of 1st Embodiment of this invention from the front side obliquely above. It is a perspective view which looked at the eyeglass 1 for one-eyed person of 1st Embodiment of this invention from the back side obliquely above. It is a figure for demonstrating the structure of the wide-angle lens 41 which is a modification of the one-eyed eyeglass 1 of 1st Embodiment of this invention. It is a perspective view of the one-eyed eyeglass 2 of the 2nd Embodiment of this invention seen from the front side obliquely above. It is a perspective view of the one-eyed eyeglass 3 of the 3rd Embodiment of this invention seen from the front side obliquely above. It is a perspective view which looked at the eyeglass 3 for one-eyed person of 3rd Embodiment of this invention from the back side obliquely above.

FIG. 1 is a perspective view of the one-eyed spectacles 1 of the first embodiment of the present invention viewed from diagonally above the front side, and FIG. 2 is a rear side of the one-eyed spectacles 1 of the first embodiment of the present invention. 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, the Y-axis direction, and the Z-axis direction of the three-dimensional Cartesian coordinate system, respectively. In the present embodiment, it is assumed that the one-eyed person who wears the one-eyed eyeglasses 1 has an extremely low visual acuity of the right eye or the right eye has lost the visual acuity when viewed from the front. This point is the same in other embodiments.

The spectacles 1 for a spectacles according to the first embodiment of the present invention are spectacles that widen the field of view of the spectacles by being worn (worn), and the spectacle frame 10 and the spectacle frame 10 are attached to the left side when viewed from the front. It has a first lens 31, a wide-angle lens 40 attached to the side of the first lens 31 and the spectacle frame 10, and a second lens 51 attached to the right side of the spectacle frame 10 when viewed from the front.

The spectacle frame 10 has rims 13 and 14 for holding lenses on the left and right sides of the front like ordinary spectacles, and the left and right rims 13 and 14 are connected by a bridge 15. 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 nose pad 17 on the left when viewed from the front is provided integrally with the wide-angle lens 40. The temple (vine) 19 is attached to the left and right rims 13 and 14 via the hinge 21.

As the first lens 31, a lens suitable for the purpose and application is selected. For example, if the one-eyed person has myopia, it will be a prescription lens for correcting it, and if it is not necessary to correct the visual acuity, a prescription lens may be used. In addition, UV cut lenses, blue light cut lenses, and the like can be used in the same manner as ordinary eyeglasses.

The first lens 31 has a size and shape that fits tightly into the rim 13 except for the right side in front view. The width (Y direction) of the first lens 31 is about 70 to 90% of the width (Y direction) of the rim 13. Therefore, when the first lens 31 is attached to the rim 13, the right side of the rim 13 is vacant in front view, and the wide-angle lens 40 is attached so as to fill this portion. The right side surface 33 of the first lens 31 is a straight line parallel to the X direction in front view (see FIG. 3).

The wide-angle lens 40 is formed by mounting an objective lens (objective-side lens) 48 and an eyepiece (eyepiece-side lens) 49 on a tubular body 43, similarly to a conventional wide-angle lens. Normally, a wide-angle lens is classified into wide-angle, standard, and telephoto, and further includes a fisheye lens and an ultra-wide-angle lens, but the same applies to the wide-angle lens 40 used here, and an appropriate selection can be used from these. .. Here, the objective lens 48 and the eyepiece lens 49 may each be composed of a plurality of lens groups, and the wide-angle lens 40 may further include another lens and another lens group. The focal length of the wide-angle lens 40 is set according to the eyesight of the user. Further, as the wide-angle lens 40, one having a function of cutting UV (ultraviolet rays) or blue light can be used.

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

The thickness of the tubular body 43 (in the Z direction) is such that the back surface of the cylinder 43 does not come into contact with the face of the one-eyed person when the eyeglasses 1 for the one-eyed person are worn. When it is necessary to increase the thickness (Z direction) of the tubular body 43 from the viewpoint of focal length, etc., adjust the positions of the nose pads 17 and 18, and the back surface of the tubular body 43 is the face and eyes of the one-eyed person. Avoid contact.

The objective lens 48 mounted on the front side of the cylinder 43 and the eyepiece 49 mounted on the back side of the cylinder 43 are in front view so as to match the front view shape and the back view shape of the cylinder 43, 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 size of the first lens 31 and the wide-angle lens 40 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 against each other in front view is the size that fits into the rim 13 without a gap. It has become. In the present embodiment, the wide-angle lens 40 is adhered to the right side of the front surface of the rim 13 so that the front surface portion 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 in front view.

In general spectacles, nose pads are provided on the left and right rims, or nose pads are attached to the left and right rims, respectively. However, in the spectacles for the eyeglass 1 of the present embodiment, the rim 14 has a nose pad 18. Although it is provided, the rim 13 is not provided with a nose pad. Instead, the tubular body 43 of the wide-angle lens 41 is provided with a nose pad 17 on the left side when viewed from the front. In the present embodiment, the nose pad 17 is integrated with the tubular 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 tubular body 43, the tubular body 43 can be provided as compared with the case where the nose pad 17 is provided on the rim 13. Can be large (wide). Making the cylinder 43 larger (wider) is preferable because it leads to an expansion of the field of view.

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

In the one-eyed spectacles 1 of the present embodiment, the left and right rims 13 and 14 have the same shape and size. Therefore, by fitting the second lens 51 to the rim 14 on the right side, the left and right balance is improved in appearance, and the appearance is also good. Further, if the weight of the second lens 51 is the same as the total weight of the first lens 31 and the wide-angle lens 40, the left-right balance is improved when the one-eyed spectacles 1 are worn, and it becomes easier to wear the second lens 51.

The one-eyed spectacles 1 can be worn and used in the same manner as ordinary spectacles. Since the one-eyed eyeglass 1 is provided with the wide-angle lens 40 near the nose, the field of view is widened.

When looking at an object with one eye, the field of view is narrower than when looking at an object with both eyes. By using the one-eyed eyeglasses 1 of the first embodiment, the field of view can be widened, but the second lens 51 may be removed in order to further expand the field of view. Since the second lens is basically for improving the appearance, there is no functional problem even if it is not provided. Further, the one-eyed eyeglasses 1 of the first embodiment have the same shape and size of the left and right rims, 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 a configuration of a wide-angle lens 41 which is a modification of the one-eyed eyeglasses 1 of the first embodiment of the present invention. The same configurations as those of the one-eyed eyeglasses 1 of 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 one-eyed eyeglasses 1 shown in FIGS. 1 and 2, the wide-angle lens 40 is fitted and adhered to the rim 13, but the wide-angle lens 41 shown in FIG. 3 is fitted and fixed to the groove of the rim 13 without being adhered. It is possible. The wide-angle lens 41 is provided with a protrusion 45 that fits into the groove of the rim 13 on the outer periphery of the front surface of the tubular body 43 except for the left side surface 44. By fitting the protrusion 45 into the groove of the rim 13, it can be fixed to the rim 13 in the same manner as the first lens 31.

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

If the wide-angle lens 41 and the first lens 31 shown in FIG. 3 are used, they can be firmly fixed by fitting them into the rim 13 in the same manner as the conventional spectacles, so that the existing spectacle frame can be used. The eyeglasses 1 for a one-eyed person can be easily manufactured.

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

The one-eyed spectacles 2 of the second embodiment have the same basic configuration as the one-eyed spectacles 1 of the first embodiment, but the structure of the rim 13 on the left side when viewed from the front is different from that of the one-eyed spectacles 1. In the one-eyed spectacles 1 of the first embodiment, the wide-angle lens 40 is fitted and adhered to the rim 13, whereas in the one-eyed spectacles 2 of the second embodiment, the tubular body 43 of the wide-angle lens 40 is the rim 13. It is a part.

Specifically, a rim 13 into which the first lens 31 is fitted is provided on the left side surface 44 of the tubular body 43 in front view. Therefore, the bridge 15 connecting the left and right rims is connected to the tubular body 43 of the wide-angle lens 40. The left side surface 44 of the tubular body 43 is provided with a concave groove 46 (see FIG. 2) into which the right side surface 33 of the first lens 31 shown in FIG. 3 is fitted.

In the one-eyed spectacles 1 of the first embodiment, since the spectacle frame 10 has the same structure and structure as general spectacles, the one-eyed spectacles 1 can be manufactured by using the existing spectacle frame. This makes the production of the one-eyed eyeglasses 1 inexpensive and easy. The one-eyed spectacles 2 of the second embodiment cannot structurally use the existing spectacle frame as it is, but the wide-angle lens 40 can be made larger than that of the one-eyed spectacles 1 of the first embodiment. it can. Therefore, the one-eyed spectacles 2 has an advantage that the field of view can be wider than that of the one-eyed spectacles 1.

Further, in the one-eyed spectacles 2, since the wide-angle lens 40 is integrated with the spectacle frame 11, it is possible to completely prevent the wide-angle lens 40 from falling off from the spectacle frame 11. The safety of the one-eyed spectacles is more important than that of the conventional general spectacles, and the one-eyed spectacles 2 in which the wide-angle lens 40 is completely prevented from falling off are preferable.

FIG. 5 is a perspective view of the one-eyed eyeglasses 3 of the third embodiment of the present invention viewed from diagonally above the front side, and FIG. 6 is a rear side view of the one-eyed eyeglasses 3 of the third embodiment of the present invention. It is a perspective view seen from diagonally above. The same configurations as those of the one-eyed eyeglasses 1 of the first embodiment shown in FIGS. 1 to 3 are designated by the same reference numerals, and the description thereof will be omitted.

The one-eyed spectacles 3 of the third embodiment has the same basic configuration as the one-eyed spectacles 1 of the first embodiment, but the spectacle frame 12 is a rimless frame, so-called rimless spectacles. The basic configuration of the wide-angle lens 42 is the same as that of the wide-angle lens 40 of the one-eyed eyeglasses 1 of the first embodiment, but the wide-angle lens 42 has a mounting seat 47 for mounting the first lens 31 on the tubular 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 is flush with the front surface of the wide-angle lens 42. One end of the bridge 15 is connected to the tubular body 43 of the wide-angle lens 42, and the other end is connected to the second lens 51.

Since the one-eyed spectacles 3 of the third embodiment is a rimless frame, it is lighter than a spectacle frame with a rim, and since there is no rim, the field of view is widened.

As described with reference to the first to third embodiments, the one-eyed spectacles according to the present invention are all provided with a wide-angle lens, so that the one-eyed spectacles can be widened in the same way as ordinary spectacles. .. In addition, the width of the wide-angle lens is set to be relatively narrow, and since it is attached to the nose pad side, a large front field of view can be obtained.

Although the one-eyed spectacles according to the present invention have been described above using the first to third embodiments, the one-eyed spectacles according to the present invention are not limited to the above embodiments and the gist is not changed. It can be changed and used within the range.

As described above, a preferred embodiment has been described with reference to the drawings, but those skilled in the art will easily assume various changes and modifications within a self-evident range by looking at the present specification. Therefore, such changes and amendments are construed as being within the scope of the invention as defined by the claims.
