Description

The present invention relates to eyeglasses that are convenient when looking at a book or a smartphone while lying down.

You may have to wear glasses when you lie down and look at a book or smartphone at bedtime. However, when I put on my glasses and lie down and sleep, the temples of my glasses hit my face and hurt. Also, if you return from sideways to your back, the glasses may shift and the distance to your eyes may not match, and you need to make adjustments each time.

Patent Document 1 describes a configuration in which a temple (vine) is eliminated and a frame of eyeglasses is adhered to the face with an adhesive material so that reading can be performed while lying down.

Patent Document 1: Japanese Patent No. 6162450

The present inventor also followed almost the same experimental process as that described in Patent Document 1 until the final form was reached, but all of them failed. From that experience, it has been found that the spectacles described in Patent Document 1 have a problem that the ear side end of the frame of the spectacles shifts against the pillow when lying sideways. In addition, since the frame of the spectacles is only adhered to the face with an adhesive material, there is a problem that the spectacles tend to shift due to aged deterioration when the spectacles are repeatedly turned sideways or on their backs, and the spectacles must be adjusted each time. Furthermore, sticking to the face with an adhesive has a problem that it causes a rash and allergies for people with sensitive skin.

An object of the present invention is to solve the above-mentioned problems and to realize eyeglasses that do not easily shift even when lying on their backs or sideways and that do not hurt their faces.

It is a front view explaining the spectacles in Example 1 of this invention. It is a perspective view explaining the spectacles in Example 1 of this invention. It is a figure explaining the state when the spectacles are put on in Example 1 of this invention.

The eyeglasses 10 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a front view illustrating the spectacles according to the first embodiment of the present invention. FIG. 2 is a perspective view illustrating the spectacles according to the first embodiment of the present invention. FIG. 3 is a diagram illustrating a state when wearing glasses according to the first embodiment of the present invention, and FIG. 3A is a diagram illustrating a state when a person wears the glasses according to the first embodiment of the present invention. (B) is a figure explaining the positional relationship between the spectacles and the pupil in Example 1 of the present invention.

The spectacles 10 in the first embodiment are composed of a frame 8, a lens 3 (3a, 3b) made of synthetic resin or glass, and a temple 5 (5a, 5b) made of an elastic rubber cord. The frame 8 can be made of any material such as synthetic resin, metal, and tortoiseshell. In Example 1, the temple 5 (5a, 5b) is made of an elastic rubber string, but the present invention is not limited to this and can be appropriately changed. For example, it may be made of a non-elastic material such as a cotton string or a synthetic resin, and any string-shaped material can be adopted. Desirably, the temples 5 (5a, 5b) are formed in a flat string shape to prevent the face from being hurt when lying sideways.

The frame 8 has a main rim 1 (1a, 1b) that supports the lens 3 (3a, 3b) at the upper part (forehead side), the nose side part, and the lower part (buccal side), and the lens 3 (3a, 3b) at the ear side. It is composed of a side rim 2 (2a, 2b), a nose pad 9 (9a, 9b), and a bridge 4 that support the lens.

Here, the main rim 1a indicates the main rim for the left eye, and the main rim 1b indicates the main rim for the right eye. Similarly, the side rim 2a, lens 3a, temple 5a, nose pad 9a, cover 7a, and stopper 6a are for the left eye, and the side rim 2b, lens 3b, temple 5b, nose pad 9b, cover 7b, and stopper 6b are for the left eye. Is shown.

The main rim 1 (1a, 1b) supports the lens 3 (3a, 3b) at the upper part, the nasal side portion, and the lower part, and has a substantially arc shape near the nasal side portion, which spreads at the upper part and the lower part, and is nasal side. The portion has a shape in which the upper part and the lower part are connected, but the present invention is not limited to this and can be changed as appropriate. For example, the shape may be substantially arcuate as a whole, or may be quadrangular or hexagonal, and it is desirable that the distance between the upper part and the lower part is at least large so as to cover a large pupil. This makes it possible to prevent the main rim 1 (1a, 1b) from hitting the dents of the eyes or getting into the eyes.

The side rims 2 (2a, 2b) support the lens 3 (3a, 3b) on the ear side, and have a rounded shape so that the middle portion is widened and the upper and lower portions are gently narrowed. Not limited to this, it can be changed as appropriate. For example, the upper part and the lower part may have a roundness larger than that shown in FIG. 1, and the upper part and the lower part may be tapered and narrowed. The upper and lower parts of the side rims 2 (2a and 2b) have a rounded shape or a tapered shape so that the side rims 2 (2a and 2b) hit the pillow and the glasses 10 shift even if the glasses 10 are turned sideways. Can be prevented.

In the first embodiment, the frame 8 provided with the side rims 2 (2a, 2b) is configured, but the configuration is not necessarily limited to this, and changes can be made as appropriate. For example, the frame may be configured without either one or both the left and right side rims 2, and at least the upper and lower portions of the frame and the ear side end of the lens may have a rounded shape or a tapered shape.

Further, in the first embodiment, the main rim 1 (1a, 1b) and the side rim 2 (2a, 2b) are bonded with an adhesive at the upper part and the lower part of the ear side end portion, but the present invention is not necessarily limited to this. It can be changed as appropriate. For example, the main rim 1 (1a, 1b) and the side rim 2 (2a, 2b) may be fitted, or the main rim 1 (1a, 1b) and the side rim 2 (2a, 2b) are integrated in the first place. May be.

A nose pad 9 (9a, 9b) is provided on the nose side of the main rim 1 (1a, 1b) so that the frame 8 is supported by the nose. Further, the main rim 1a and the main rim 1b are connected by a bridge 4 at the upper part of the nose.

The cover 7 (7a, 7b) is provided along the main rim 1 (1a, 1b) so as to be in contact with the face. The cover 7 (7a, 7b) is provided to keep the distance between the inner main surface of the lens 3 (3a, 3b) and the pupil I (Ia, Ib) at a predetermined length. Further, by having the nose pad 9 (9a, 9b), the distance from the inner main surface of the lens 3 (3a, 3b) to the pupil can be kept constant. The predetermined distance (distance between the corneal vertices) between the lens and the pupil in Example 1 is set to 12 mm. This allows the widest field of view.

In Example 1, the distance between the corneal vertices is set to 12 mm, but the distance is not necessarily limited to this and can be changed as appropriate. For example, it may be about 10 mm or 11 mm, which is slightly shorter than 12 mm, or about 13 mm.

Further, in the first embodiment, in order to keep the lens and the pupil at a predetermined distance, the cover 7 (7a, 7b) is provided so as to be in contact with the face along the main rim 1 (1a, 1b). , Not necessarily limited to this, and can be changed as appropriate. For example, the cover 7 (7a, 7b) may be provided in a part along the main rim 1 (1a, 1b), or a plurality of rod-shaped protrusions may be provided on each of the main rim 1a and the main rim 1b. At this time, the end shape may be made large or round so that the rod-shaped protrusion does not get injured in the eyes.

The temple 5 (5a, 5b) is made of an elastic rubber cord as used for a mask. As a result, even if the person wears the glasses 10 and sleeps sideways, the temple does not bite into the face and feel pain. Further, it has stoppers 6 (6a, 6b) so that the length of the elastic cord can be adjusted according to the size of each person's face. The stopper 6 (6a, 6b) is made of synthetic resin and has two holes so that the rubber cord can pass through, and the length can be adjusted by pulling the end portion of the rubber cord. The frame 8 side end of the temple 5 (5a, 5b) made of a rubber cord is connected to the cover 7 (7a, 7b) with a hole. The stopper 6 (6a, 6b) is configured to have two holes, but the stopper 6 (6a, 6b) is not necessarily limited to this and can be changed as appropriate. For example, a clip may be used to fasten the elastic cord.

In the first embodiment, the end of the temple 5 (5a, 5b) made of a rubber string on the frame 8 side is configured to be connected by making a hole in the cover 7 (7a, 7b), but the present invention is not necessarily limited to this. It is not possible to change it as appropriate. For example, it may be configured to be connected by a screw, or it may be configured to be hooked by providing a protrusion on the main rim 1 (1a, 1b) or the side rim 2 (2a, 2b). As a result, when the elastic cord is stretched due to deterioration over time, it can be easily replaced.

The lens 3 (3a, 3b) may be for presbyopia, myopia, or hyperopia, and may be a lens so that a book or a smartphone can be seen.

Next, the length between the ear side ends of the left and right lenses 3 (3a, 3b) will be described. When sleeping and looking at a book or smartphone, the field of view may be limited, and by shortening the length between the ear side ends of the left and right lenses 3 (3a, 3b), the lens 3 when lying sideways It is possible to prevent (3a, 3b) and the side rims 2 (2a, 2b) from coming into contact with the pillow or the like and shifting from the face.

After more than a year of experimentation, it has been found that the length between the lateral edges of the frame and the lens should be at least shorter (less than) the length between the eyes of the person wearing the spectacles (less than). Less than C in FIG. 3 (b)). As a result, even if you lie on your back or sideways, your glasses will not shift and your face will not hurt, and you will be able to see books and smartphones. Also, more preferably, the length between the left-right ends of the lens is longer than the length between the left-right outer ends of the iris when facing straight forward (B in FIG. 3B), and both eyes. It may be less than the length between the eyes. An image of wearing the glasses 10 in that state is shown in FIG. 3 (a). Even for those who focus on looking at things with one eye, if it is about 6.5 mm longer than the outer edge of the iris, sufficient visibility can be secured (Japanese adults have an eye size of 24 mm and an iris size of 11 mm. Since it is said to be about, (24-11) ÷ 2 = 6.5 mm for one side of the white eye.).

If the length between the left and right ends of the lens is at least less than the distance between the eyes of the person wearing the spectacles, even if the side rims 2 (2a, 2b) are provided, when lying sideways. The glasses 10 do not shift or the face does not hurt.

The interpupillary distance (A in FIG. 3B) is said to have an average value of 64 mm for Japanese men and 62 mm for Japanese women. Then, in the case of the average Japanese man, at least the length between the left and right ends of the lens is 75 mm or more, which is the length between the outer ends of the iris (the size of the Japanese iris is about 11 to 12.5 mm). (When the interpupillary distance plus 11 mm) and the length to the iris of both eyes is less than 88 mm (when the distance from the outer edge of the iris to the iris is 6.5 mm on each side). If the size of the iris is large enough, the iris will not slip even when lying on its back or sideways, and the iris will not hurt the face.

And for the average Japanese man, the most desirable length between the lateral ends of the lens is an intermediate length greater than or equal to the length between the lateral ends of the iris and less than the length to the corners of both eyes 81. It is 5 mm. When the side rims 2 (2a, 2b) are provided, the distance between the side rims 2 (2a, 2b) (that is, the distance between the left and right frames) may be less than 88 mm between the eyes. (See Table 1.)

Further, in the case of an average Japanese woman, at least the length between the left and right ends of the lens is 73 mm or more, which is the length between the outer ends of the iris (as described above, when the interpupillary distance is 62 mm plus 11 mm). ), And if the eyeglasses have a size of less than 86 mm to the eyes of both eyes (as described above, when the distance from the outer edge of the iris to the eyes is 6.5 mm on each side), the eyeglasses should be turned upside down. The glasses can be made so that they do not slip easily even when lying sideways and do not hurt the face.

And for the average Japanese woman, the most desirable length between the lateral ends of the lens is an intermediate length greater than or equal to the length between the lateral ends of the iris and less than the length to the corners of both eyes 79. It is 5 mm. When the side rims 2 (2a, 2b) are provided, the distance between the side rims 2 (2a, 2b) may be less than 86 mm between the eyes. (See Table 1.)

Pupillary distance A Iris distance B Distance between left and right ends Lens length between left and right ends Male average 64 75 88 81.5 Male large 70 81 94 87.5 Female average 62 73 86 79.5 Female small 56 67 80 73 .5
Note) ・ Distance between the left and right edges C = distance between the ends of the iris B + 13 (when the distance from the outer edge of the iris to the edge of the iris is 6.5 mm each on the left and right) ・ Lens length between the left and right edges = distance between the ends of the iris B + 13/2 (Intermediate length of BC)

For children and foreigners, the length between the left and right ends of the lens may be set appropriately. That is, the distance between the outer ends of the iris and the distance between the eyes can be estimated from the distance between the pupils of the person who wears the spectacles, and the spectacles having the ideal lens length between the ends in the left-right direction may be made. That is, the spectacles have a lens length between the left and right ends that is greater than or equal to the distance between the outer edges of the iris on both sides of the person wearing the spectacles and less than the distance from the outer edges of the iris of both eyes to the edge of the eye.

As described above, in the first embodiment, the spectacles are convenient for viewing a book or a smartphone while lying down, and the length between the left and right ends of the frame and the lens is at least the eyeglasses of both eyes of the person who wears the spectacles. It is possible to realize eyeglasses characterized by being less than the length between.

The spectacles of the present invention can be widely applied to a field in which a healthy person or a person who is easy to sleep when lying down due to lumbar spinal canal stenosis or the like but cannot sleep on his back can see a book or a smartphone while sleeping.
