Abstract

(57) [Summary] [Problem] To provide eyeglasses that are easy to see when performing work or reading at hand and that also reduce eye fatigue. SOLUTION: The angle of inclination of the front part holding the lens with respect to the crane is set to a value of 13 ° to 17 ° so that the optic axis of the lens and the line of sight can be brought close when working at hand.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to eyeglasses that are easy to see and perform when working at hand.

[0002]

[Prior art]

 Glasses can be broadly divided into myopic glasses and far-sighted glasses. Broadly speaking, there are glasses for far vision and near vision (reading glasses). People with myopia can see far away by wearing the above-mentioned far-sighted glasses, but if they have presbyopia, they can wear the near-sighted glasses when reading newspapers or magazines. Come to see. The same applies to people with hyperopia.

[0003] Fig. 3 shows conventional general glasses. The front portion of the glasses is connected to both rims (a) and (b) by a connecting member (b), and the rims (a) and (b) are connected. On the outside is brazed (C) and (C). The vines (c) and (c) are attached to the cranes (d) and (d) via joints such as hinges so as to be foldable. Lenses (f) and (f) having a predetermined power are fitted to the rims (a) and (a).

The glasses are hung on the face, but the front part supports the nose pads (e) and (e) attached to the inside of the rim by contacting the nose with the nose pads (e) and (d). Extends from the side of the face to the back of the head and engages with the ears. Therefore, the glasses can be worn stably, but the front part is not perpendicular to the vine (d) but has an inclination angle θ, and the inclination angle θ is that of general glasses. 8 ° to 12 °.

When wearing glasses, a person's line of sight is not horizontal at infinity but rather downward. In order to align the optical axis of the lens with this downward line of sight, the front part of the glasses is inclined with an inclination angle θ. However, when the worker wears the glasses and works at hand, his or her eyes are directed further downward, so that it is difficult to see with the conventional inclination angle θ. Particularly for those who use reading glasses, it is difficult to work and the eyes are easily tired. Conventionally, the front part is displaced downward, making it easier to work at hand. However, in the case of using a bifocal lens (especially a progressive multi-accumulation lens), if the front portion is shifted downward, the clear vision range is narrowed, and the front portion is shifted downward, making it difficult to see.

[0006]

[Problems to be solved by the invention]

 Thus, when working at hand or reading newspapers or magazines, there is a problem that eyes are easily tired with conventional megane. The problem to be solved by the present invention is this problem, and provides easy-to-use glasses for fine manual work.

[0007]

[Means for solving the problem]

 The glasses of the present invention are suitable for manual work or reading while lowering the line of sight, and the inclination angle of the front part is made larger than before. That is, the conventional inclination angle is about 9 °, but in the present invention, the inclination angle θ is about 15 °. The allowable range is 13 ° to 17 °.

Incidentally, the material of the frame constituting the glasses of the present invention is not limited, for example, when it is made of metal or resin, or when it is made of a combination of metal and resin. The specific form and structure of the glasses are also free. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0009]

【Example】

 FIG. 1 is a side view showing the glasses of the present invention. The basic form of the glasses is the same as that shown in FIG. 2 above, and vines 2 and 2 are attached to both sides of the front part 1 so as to be foldable. The front part 1 has both rims into which lenses are fitted, and the rim 3 is brazed to the outside of the rim. However, the inclination angle θ of the front part 1 is larger than that of conventional glasses. In addition, Yoroy 3 is configured.

FIG. 2 shows the yoke 3 alone. The yoke 3 is composed of a front piece 4 and side pieces 5, and is formed at approximately 90 ° so that a straight plate material becomes the front piece 4 and side pieces 5. In addition to being bent, the front piece 4 is twisted and inclined. If the angle of inclination is the above θ and the front piece 4 is brazed to the outside of the rim, the direction of the vine 2 and the angle of the front part 1 will be the angle of inclination θ.

The inclination angle θ is generally about 15 °, but the allowable range is 13 ° to 17 °. Glasses with a maximum tilt angle of 17 ° are suitable for finer manual work, and glasses with a minimum tilt angle of 13 ° are suitable for relatively rough manual work.

[0012] The specific structure of the glasses of the present invention is not limited, and may be, for example, frameless glasses having no rim. It may be configured as a type of glasses that holds the lower side. Of course, the front frame can be formed so that the resin-made spectacle frame has the above-mentioned inclination angle. The same applies to glasses having a mechanism that can be changed to the inclination angle θ.

[0013] As described above, the glasses of the present invention have the front portion having an inclination angle of 13 ° to 17 °, and the following effects can be obtained.

[0014]

[Effect of the invention]

 In the glasses of the present invention, the front portion has an inclination angle of about 15 ° with respect to the vine. This is larger than conventional glasses and is suitable for working at hand or reading. That is, when performing a manual operation, the line of sight is necessarily directed downward, and the inclination angle of the Freon portion is close to the optical axis of the lens, so that it is easy to see. Also, since the line of sight is almost perpendicular to the lens surface, the optical distortion of the lens is minimized, so that it is easy to see. This provides more optical advantages for bifocal lenses. That is, an effect of enlarging the clear visual region and reducing distortion is obtained. Therefore, eyestrain is less and the glasses can be stably put on the predetermined position.
