Description

The present invention relates to glasses using plastic lenses, and more particularly, to glasses having improved visibility and air feeling during use, and functional parts made of ceramic disposed in each part of the glasses frame or the lenses constituting the glasses. .

Conventionally, glasses generally consist of a glasses frame and a pair of lenses.
The eyeglass frame includes a front that holds the pair of lenses, a pair of temples that extend rearward from both ends of the front and that is foldably supported by the front, and protrudes rearward from the center of the front. And a pair of nose pads.
The lens is a so-called meniscus lens that is held on the front and is made of a transparent material.

According to the glasses having such a configuration, the user hangs the left and right temples on the upper side of the ear on the left and right sides of his / her head, and makes the nose pads contact the left and right sides of his / her nose part. Is installed.
As a result, the left and right lenses are held in front of the user's eyes, respectively, and the user can see the front through the left and right corresponding lenses with both eyes. At that time, light enters the eye through the lens from the front, is corrected by the refractive action of the lens body of each eye, and further by the refractive action of each lens of the glasses, and is correctly connected to the retina of the user's eye. It has come to be imaged.

By the way, as a lens for glasses, a plastic lens is currently used in many cases from the viewpoint of easy processing and light weight.
However, in the case of a plastic lens, since the hardness of the plastic material itself is lower than that of the glass lens material, it is easily scratched and the sharpness of the field of view through the lens may be felt sweet. is there.
Here, the point of being easily scratched can be solved by providing a coating layer having a higher hardness on the lens surface, but the sweetness of sharpness has not been solved yet.

Moreover, in the case of a plastic lens or a glass lens, the lens is positioned in front of the user's eyes, and therefore the lens exists between the object to be visually recognized and the user's eyes. For this reason, compared with the case where the object is directly visually recognized by the naked eye, the presence of the lens itself impairs the so-called feeling of air in which the user feels short of breath, that is, the feeling that the eyes are tightly breathed. Will fall.
Here, the feeling of air is a state and atmosphere that makes the user feel uncomfortable by harmonizing the glasses as a whole. For example, if you take a glass of ceramics and a glass of glass, you can see it. In addition, ceramic cups that are not covered with glaze up to the hill, give the user a soft and familiar feeling from the material that rubs air compared to holding a glass cup.
It is an important element in glasses that are used for a long time from the viewpoint of being able to be used comfortably without giving fatigue or laziness, but it is a sensory element obtained from the material. It is used as an expression that communicates with the feel of touching the air and the atmosphere.

The problem of reduced visibility due to the loss of the air feeling is that, especially for users with strong lenses, the area that can be seen without distortion is limited to a narrow area near the center of the lens. When an object moves, the feeling of discomfort is much greater than that seen directly with the naked eye.

Furthermore, micro vibrations or fluctuations that occur in plastic lenses and frames also contribute to the sharpness of the field of view through the lenses. That is, factors such as micro vibration or fluctuation of plastic lens include large degree of thermal shrinkage due to temperature change, weak distortion resistance due to external force, charging property due to high insulation performance, etc. Although the physical changes in the numerical values are negligible, the focal distance, the focal position error, and the like accompanying this change affect the perceptible level and cannot be overlooked.
Nevertheless, these parts have been neglected until now.

The present invention has been made in view of the above points, and has an object to provide glasses and functional members that are arranged in each part of the glasses so as to improve the sharpness of the field of view and the feeling of air during use.

According to the first configuration of the present invention, the above object is achieved by a pair of temples that hold a pair of lenses, a pair of temples that extend rearward from both ends of the front and are supported with respect to the front in a foldable manner. In glasses comprising a pair of nose pads protruding rearward from the center and a pair of plastic lenses held on the front of the glasses frame, each part of the glasses frame or any of the lenses is made of ceramic. This is achieved by glasses with functional members.

In the glasses according to the present invention, the functional member is preferably formed of a ceramic chip piece.
However, the present invention is not limited to this, and a similar functional member can be obtained by forming a similar chip using a hard material other than ceramic.

In the glasses according to the present invention, the chip piece preferably has a hole in the center thereof.

In the glasses according to the present invention, the chip piece preferably has a circular outer shape.

In the glasses according to the present invention, the chip piece preferably has a polygonal outer shape.

In the eyeglasses according to the present invention, the functional member is preferably inserted and fixed in a through hole provided in the eyeglass lens.

In the glasses according to the present invention, the functional member is preferably formed in a rod shape corresponding to the dimension of the through hole.

In addition, according to the second configuration of the present invention, the above object is achieved by a front holding a pair of lenses, a pair of temples extending rearward from both ends of the front and supported to the front in a foldable manner. , Any one of each part of the eyeglass frame or the lens in eyeglasses comprising a pair of nose pads protruding rearward from the center of the front and a pair of plastic lenses held on the front of the eyeglass frame This is achieved by a functional member made of ceramic disposed in

According to the said structure, the hardness of the spectacles frame or lens in the peripheral area | region of a functional member is locally improved by providing a functional member in each part or lens of a spectacles frame. This suppresses minute vibrations or fluctuations generated in the plastic lens and the frame, and improves the sharpness of the field of vision based on the low hardness in the glasses using the plastic lens.
In addition, the functional member has a characteristic of not having a vibration peak in a certain direction, which is characteristic of a ceramic having a polycrystalline structure, an excellent shape stability with respect to environmental changes, and a feature of high hardness. It functions as a small damper and suppresses minute vibrations generated in plastic lenses and frames, while converting the vibration energy into self-resonant energy proportional to the shape and size of the functional member, resulting in each part of the glasses Absorb and align the small vibration differences.

And a user tends to perceive such a local change in hardness preferentially as a change in hardness in the entire glasses. Therefore, the sharpness of the field of view is improved not over the local area but over the entire field of view of the user.
In addition, the decrease in the air feeling due to the presence of the lens between the object to be visually recognized by the user and the user's eyes is not only the main factor of the increased hardness feeling due to the functional member, but also the pores in the porous ceramic. Existence, air feeling is enhanced by a minute space surrounded by a hard material called a central hole provided in the functional member, and the air feeling is enhanced as a whole lens, and visibility when using glasses is improved. It will be.
Furthermore, it is felt that the sharpness of the field of view and the feeling of air are improved over the entire visual field of the user, not as a local thing due to self-resonance.

FIG. 1 shows a configuration of an embodiment of glasses according to the present invention.
In FIG. 1, the glasses 10 are composed of a glasses frame 11, a pair of lenses 20, and a functional member 30.

The eyeglass frame 11 has a publicly known configuration, and includes a front 12 that holds a pair of lenses 20, a pair of temples 13 that extend rearward from both ends of the front 12, and a rear portion that protrudes from the center of the front 12. And a pair of nose pads 14.

In the illustrated case, the front 12 is made of metal and is composed of two frames 12a and 12b that respectively hold a pair of lenses 20, and these frames 12a and 12b are connected to each other by a bridge 12c. Yes.

Similarly, the temple 13 is made of metal and is bent downward so that the vicinity of the rear end of the temple 13 is applied to the user's ear, and in the illustrated case, the rear end portion of the user's ear is In order to soften the hit, for example, a plastic ear pad 13a is provided.
The nose pad 14 is made of, for example, a soft plastic such as silicon, and is supported so as to be swingable by, for example, a crings (not shown) so that the right and left sides of the user's nose can be properly contacted.

The lens 20 is a plastic lens, and is formed as a convex or concave meniscus lens having a diopter adjusted according to the visual acuity of the left and right eyes of the user.

As shown in FIG. 2, the functional member 30 is attached to the surface of each lens 20 in the vicinity of the side edge of each lens 20. In FIG. 2, the functional member 30 is arranged at one place on the front surface of the lens 20, but the functional member 30 is not limited to this, and may be arranged at a plurality of places including the back face and the side face.

Here, the functional member 30 is made of a ceramic material in a broad sense such as fine ceramics such as SiC and alumina, or pottery and porcelain, and is formed as a thin disk-shaped ceramic chip as shown in FIG. A central hole 31 is provided. The center hole 31 may be omitted as shown in FIG. 4 in the case of a so-called porous ceramic material having many pores contained in the ceramic material constituting the ceramic chip.
In this case, the functional member 30 has, for example, a thickness t of about 0.2 mm to 2 mm, preferably 0.5 mm, an outer diameter D of about 0.8 mm to 4 mm, preferably an outer diameter of 2 mm, and an inner diameter d of the center hole of 0.2 to 0.2 mm. About 2 mm, preferably 0.6 mm is selected.

Further, the functional member 30 does not have to be in a disk shape. For example, as shown in FIG. 5, in the case of a thin octagonal plate having a center hole, or a porous ceramic material, the functional member 30 is shown in FIG. As shown, it may be a thin regular octagonal plate having no central hole.
In this case, the functional member 30, for example, has a thickness t of about 0.2 mm to 2 mm, preferably 0.5 mm, an outer dimension D of about 1 mm to 4 mm, preferably an outer dimension of 2 mm, and an inner diameter d of the center hole of 0.2 to 2 mm. The degree, preferably 0.5 mm is selected.

Furthermore, the functional member 30 may have a center hole like an angel shape as shown in FIG. 9, for example.
In this case, the functional member 30, for example, the thickness t is about 0.3 mm to 2 mm, preferably 0.4 mm, the outer diameter D is about 1 mm to 4 mm, preferably the outer diameter 2 mm, the inner diameter d of the center hole is about 0.1 to 2 mm, Preferably, it is selected to be 0.4 mm, and the radius r is about 0.2 mm to 1 mm, preferably 0.4 mm.
Here, the shape indicated by the radius r is not necessarily the shape indicated by the radius, and may be formed by an ellipse, a curve, or a partially straight line.

In addition, the functional member 30 has, for example, a hemispherical center hole as shown in FIG. 10 or a porous ceramic material that does not have a hemispherical center hole as shown in FIG. There may be.
In this case, the functional member 30 has a thickness t of about 0.4 mm to 2 mm, preferably 1 mm, an outer diameter D of about 0.8 to 4 mm, preferably an outer diameter of 2 mm, and an inner diameter d of the center hole of about 0.2 mm to 2 mm. Preferably, the radius r is selected to be about 0.6 mm and the radius r is about 0.4 mm to 2 mm, preferably 1 mm.
Here, the shape indicated by the radius r is not necessarily the shape indicated by the radius, and may be formed by an ellipse, a curve, or a partially straight line.

Note that the circular portion shown as the outer diameter D is not necessarily a circle, but may be an ellipse or the like.
In this way, by selectively adjusting the shape and size of the functional member 30, the self-resonant mode is easy to convey a sense of a feeling of air in combination with the material feeling peculiar to ceramics without impeding the field of view. Become.
The material feeling here refers to the feeling brought about by the structure that encloses air, such as the presence of pores in ceramics, or in the case of materials with few pores, a minute space surrounded by a material called a central hole provided in the functional member. is there.
The shape of the functional member 30 shown in FIG. 3, FIG. 4, FIG. 5, FIG. 9, FIG. 10, and FIG. 11 has been found to achieve both the air feeling and the sharpness of the field of view.

Further, in general ceramics and porcelain, surface treatment is performed using glaze, but it is expected that the sharpness in the field of view can be further improved by surface treatment of the end surface of this functional member with glaze or the like.

The glasses 10 according to the present invention are configured as described above. In use, the user hangs the ear pad 13a of the temple 13 on the upper side of both ears, and the nose pad 14 on the left and right sides of the nose. The eyeglasses 10 are attached by bringing them into contact with both sides.
In this state, light from the outside enters each of the user's eyes via both lenses 20, and further enters the retina through the lens body of each eye.
Then, due to the refractive action of the lens 20 and the refractive action of the eye lens body, the image of the object is correctly formed on the retina, and the object is visually recognized.

Here, since the functional member 30 is adhered to the lens 20, the hardness of the lens 20 is locally increased.
On the other hand, the user tends to perceive such a local change in hardness as a change in hardness in the entire glasses 10. Therefore, the sharpness of the field of view through the lens 20 is improved over the entire field of view of the user.
In addition, the decrease in the air feeling due to the presence of the lens 20 between the object to be visually recognized by the user and the user's eyes is also caused by the increase in the hardness by the functional member 30 as a whole. Furthermore, since the glasses 10 as a whole are improved, the air feeling is enhanced and the visibility when using the glasses 20 is improved.
Furthermore, the sharpness of the field of view and the feeling of air are improved over the entire visual field of the user due to the micro vibration suppressing effect and the self-resonant effect which are the functions of the functional member 30.

In the embodiment described above, the functional member 30 is attached to the surface in the vicinity of the side edge of the lens 20. However, the functional member 30 is not limited to this, and is embedded in the surface side of the lens 20, for example, as shown in FIG. May be.
That is, in FIG. 7, the functional member 30 is the same as the functional member 30 used in the glasses 10 in FIG. The functional member 30 is disposed so as to be embedded in the recessed portion 20a on the surface side near the side edge of the lens 20. Not only this but a recessed part may be provided and arrange | positioned in a back surface and a side surface.

The depth of the recessed portion 20a is selected according to the thickness of the functional member 30, so that when the functional member 30 is embedded in the recessed portion 20a, the surface of the functional member 30 is substantially the same as the surface of the lens 20. It is comprised so that it may become the same plane.
It should be noted that the depth of the recessed portion 20a is selected deeper than the thickness of the functional member 30, and after the functional member 30 is embedded in the recessed portion 20a, the filler is placed in the recessed portion 20a from above the functional member 30. The surface of the recessed portion 20a may be flush with the surface of the lens 20 by filling and curing.

According to the glasses having such a configuration, the hardness of the lens 20 is locally increased by embedding the functional member 30 in the lens 20 in the same manner as the glasses 10 shown in FIGS. And since the user perceives such a local change in hardness as a change in the hardness of the entire glasses 10, the sharpness of the field of view through the lens 20 is improved over the entire visual field of the user. Become.
Furthermore, the sharpness of the field of view and the feeling of air are improved over the entire visual field of the user due to the micro vibration suppressing effect and the self-resonant effect which are the functions of the functional member 30.

Further, as shown in FIG. 8, a through hole 20b that penetrates the lens 20 from the front surface side to the back surface side is provided near the side edge of the lens 20, and a functional member 32 having a shape corresponding to the through hole 20b is embedded. You may do it.
In this case, the through hole 20b is formed in a substantially cylindrical shape, and the functional member 32 is formed in a rod shape slightly smaller in diameter than the inner diameter of the through hole 20b. As a result, the functional member 32 is embedded in the vicinity of the side edge of the lens 20 by the functional member 32 being inserted and fixed in the through hole 20b of the lens 20.

Similarly, according to the glasses having such a configuration, the functional member 32 is embedded in the lens 20, whereby the hardness of the lens 20 is locally increased. And since the user perceives such a change in local hardness as a change in hardness in the entire glasses 10, the sharpness of the field of view through the lens 20 is improved over the entire field of view of the user, The air feeling of the glasses 10 as a whole is enhanced and the visibility is improved.
Furthermore, the sharpness of the field of view and the feeling of air are improved over the entire visual field of the user due to the micro vibration suppressing effect and the self-resonant effect which are the functions of the functional member 30.

In the above-described embodiment, the functional member 30 or 32 is disposed by sticking or embedding in the vicinity of the side edge of the lens 20. However, the functional member is not limited to this, and the functional member is disposed in other portions of the glasses 10. It may be arranged.
For example, in FIG. 1, the functional member 30 is attached to a fixed portion (arrow A) such as a krings in the nose pad 14 of the eyeglass frame 11 or in the vicinity of the boundary (arrow B) with the ear pad 13a in the temple 13. Also good.

According to such an arrangement of the functional member 30, the functional member 30 locally increases the hardness of the front 12 or the temple 13 of the glasses 10.
As a result, the user perceives such a local change in hardness as a change in the hardness of the entire glasses 10 including the lens 20, so that the sharpness of the field of view through the lens 20 is spread over the entire visual field of the user. In addition, the air feeling of the glasses 10 as a whole is enhanced and the visibility is improved.
Furthermore, the sharpness of the field of view and the feeling of air are improved over the entire visual field of the user due to the micro vibration suppressing effect and the self-resonant effect which are the functions of the functional member 30.

In the above-described embodiment, the functional members 30 and 32 are arranged in a pair of left and right with respect to the lens 20 or the temple 13, but this is not restrictive, and the left and right are symmetrical in consideration of the left and right balance. A plurality of pairs of functional members 30 or 32 may be provided at these positions.
As for the arrangement positions of the functional members 30, preferably, when the front is the front and the temple is the rear, a pair is arranged at a position where the weight balance between the front and rear is maintained, approximately 5 cm from the front of the temple. Is effective.
By arranging in this way, the self-resonant effect of the functional member 30 can be maximized.

The present invention can be implemented in various forms without departing from the spirit of the present invention.
For example, in the above-described embodiment, the functional member 30 or 32 is disposed in the vicinity of the side edge of the lens 20 or in the nose pad 14 and the temple 13, but not limited thereto, other parts of the lens 20, such as the front It is obvious that a functional member may be disposed in any part of the eyeglass frame 11 such as the 12 frames 12a and 12b, the bridge 12c, the ear pad 13a of the temple 13, or the like by sticking or embedding.

In the above-described embodiment, the functional member 30 has a circular or regular octagonal outer shape. However, the functional member 30 is not limited to this, and has a regular polygonal or elliptical outer shape with or without a center hole. Obviously it may be.

In the above-described embodiment, the shape of the central hole of the functional member 30 is not limited to a concentric circle, but may be various shapes that take into consideration the function and design, such as a polygon, a star, or a sphere. Is clear.

In the embodiment described above, the case where the functional members 30 and 32 are used for the glasses 10 has been described. However, the present invention is not limited to this, and the arrangement of the functional members 30 and 32 by sticking or embedding is a plastic. For example, it can be applied to optical devices such as a digital camera using a lens, and various devices such as a portable terminal. This improves the sharpness of the captured image and enhances the feeling of air.

Furthermore, the above-described arrangement by attaching or embedding the functional members 30 and 32 is also applied to various devices such as a portable terminal, a personal computer, and a television device having a display that provides a screen to be visually recognized by the user. It can be applied, and this improves the sharpness of the image displayed on the screen.

As described above, according to the present invention, the functional members disposed in each part of the glasses and the glasses that improve the sharpness of the field of view and the air feeling at the time of use are provided with a simple configuration.
