Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an auxiliary tool with fitting marks for fitting eyeglass lenses into frames, which is worn on the surface of eyeglass lenses in order to properly fit the eyeglass lenses into eyeglass frames. It is.

[Prior Art] It is well known that, in general, in order to correctly attach eyeglass lenses, especially multifocal eyeglass lenses, to eyeglass frames on the wearer, various types of aids with markings are required. This is what is happening. When attached to an eyeglass frame in this way, in reality, for example, the surface of the multifocal eyeglass lens is equipped with many display markings such as a power measurement position, a fitting position for wearing, a geometric center point, a horizontal reference line, etc. tools are used.

[Problems to be solved by the invention] When the above-mentioned auxiliary device with a display mark is attached to an eyeglass frame, the fitting position changes based on the individual differences of the eyeglass wearer, and it is necessary to change the fitting position. However, there is a problem in that a dedicated scale and charts must be prepared separately.

Furthermore, since the surface of the spectacle lens is not flat, there are also problems in that the use of the above-mentioned display marks lacks accuracy and requires complicated work to attach the lenses to the spectacle frame.

The present invention was developed in view of the above-mentioned problems, and aims to provide a new auxiliary tool with fitting marks that eliminates the drawbacks of various marks displayed on the surface of conventional eyeglass lenses. It is something.

[Means for Solving the Problems] That is, the present invention has one horizontal reference line passing through the geometric center point of the lens and one vertical reference line substantially perpendicular to the horizontal reference line at the center point. a corresponding vertical reference scale mark; a plurality of horizontal scale marks located above and below the horizontal reference line at the center point and symmetrically parallel to the vertical reference line; and near the left and right sides of the vertical reference scale mark; and at least one pair of left and right vertical scale marks are provided symmetrically with respect to the vertical reference scale mark in parallel to the vertical reference scale mark, and marks including the fitting points of the eyeglass lens to be processed are provided. To provide an auxiliary tool with fitting marks for eyeglass lens frame insertion, which is worn on the surface of eyeglass lenses before insertion.

In the fitting aid with a fitting mark of the present invention, the fitting mark is located near the optical center of the surface of a conventional spectacle lens such as a single focal lens or a multifocal lens, which is generally close to the geometric center point. Separately from the marks attached based on their respective characteristics, horizontal scale marks and vertical scale marks that have the meaning of scale graduations are created by arranging multiple linear marks at equal pitches in the horizontal and vertical directions. The feature is that it is added.

The length, width, interval, number, etc. of the linear horizontal scale marks and vertical scale marks can be increased or decreased or changed as necessary, depending on the characteristics of the eyeglass lens. Furthermore, these marks may be permanent, semi-permanent, hidden, or have different colors. The entire fitting mark is printed on a thin sheet of paper, plastic, or the like corresponding to the dimensions of an eyeglass lens, thereby forming an auxiliary tool with a fitting mark.

[Embodiments] Hereinafter, embodiments of the present invention will be described as shown in the accompanying drawings.

FIG. 1 of the accompanying drawings shows an embodiment of the auxiliary tool with fitting marks for fitting eyeglass lenses according to the present invention, which is applied to a progressive multifocal lens. In FIG. 1, 1 represents a left eye lens, 2 is a geometric center point mark, 3 is a horizontal reference line passing through the geometric center point, and 4 is a substance perpendicular to the horizontal reference line at the center point. This is a vertical reference line scale mark that corresponds to the vertical reference line. Therefore, the vertical reference scale mark 4 only needs to be useful as a scale mark,
It does not have to be connected to the center point mark and displayed.

Near the top and bottom of the horizontal reference line 3 of the center point mark 2 is a vertical reference scale mark 4, that is, a horizontal reference line 3 located substantially symmetrically with respect to the vertical reference line.
A horizontal scale mark 5 parallel to the vertical reference scale mark 4 is provided at a position near the left and right sides of the vertical reference scale mark 4, and furthermore, at least one left and right scale mark is provided parallel to the vertical reference scale mark 4 symmetrically with respect to the vertical reference scale mark 4.
A pair of vertical scale marks 6 are provided. Here, the scale mark is a mark used as a scale for position determination when inserting the eyeglass lens into the eyeglass frame.

FIG. 2 is a partially enlarged view of the vicinity of the center point mark 2, mainly consisting of the horizontal scale mark 5, the vertical scale mark 6, etc., in the auxiliary tool with fitting marks for inserting eyeglass lens frames shown in FIG. The positions, shapes, intervals, etc. of the horizontal scale mark 5, vertical scale mark 6, etc. are made clear by FIG. In FIG. 2, a plurality of horizontal scale marks 5 are arranged symmetrically with respect to the center point mark 2 at arbitrary distances above and below from the horizontal reference line 3, and parallel to the horizontal reference line 3 at arbitrary intervals. It is provided. Further, the vertical scale mark 6 is arranged symmetrically with respect to the vertical reference scale mark 4, with an interval equal to the interval between each of the horizontal scale marks 5 between the upper end of the horizontal scale mark 5 and the horizontal scale mark 5. A plurality of them are provided parallel to the vertical reference scale mark 4 at arbitrary intervals to the left and right of the vertical reference scale mark 4.

Although the shapes of the horizontal scale mark 5 and the vertical scale mark 6 are not particularly limited, it is preferable that they are linear since they are used as scales as described above. Further, the length, thickness, number, etc. of the linear shape are determined by oneself for the same reasons as described above. In particular, if it is longer than necessary or if there are too many, the original purpose may not be achieved, which is not preferable. Furthermore, similar consideration must be given to the arbitrarily set distances, intervals, and the like.

To explain these in detail according to Fig. 2, the horizontal scale mark 5 is 8 mm upward and 2 mm downward from the horizontal reference line 3 on both the left and right sides of the center point mark. The distance between the horizontal scale marks 5 above the horizontal reference line 3 within the distance
Four pieces are provided so that P ₁ to _{P 4} are each kept at 2 mm, and one piece is provided so that the lower interval P ₆ is kept at 2 mm. Also, the vertical reference scale mark 4 is spaced apart from the top end of the horizontal scale mark 5.
P ₅ is maintained at 2 mm, and the vertical scale mark 6 is located within a distance of 4 mm to the left and right from the vertical reference scale mark 4, and the distance Q ₁ to
Two vertical scale marks 6 are provided on each of the left and right sides, keeping Q ₄ at 2 mm. Therefore, the distance between the left and right horizontal scale marks provided symmetrically around the vertical reference line is kept at 8 mm, which is equal to the sum of the intervals Q ₁ to Q ₄ of the vertical scale marks 6.

It is necessary that the horizontal scale marks have equal intervals P ₁ to _{P 6} , and it is also necessary that the vertical scale marks have equal intervals Q ₁ to _{Q 4} . However, it is not necessary, for example, that P ₁ =Q ₁ .

FIG. 3 is a plan view showing a conventional auxiliary tool with display marks for a multifocal lens. In the present invention, in addition to the above-mentioned marks, the auxiliary tool with fitting marks for inserting eyeglass lens frames shown in FIG.
Conventional markings such as those shown in FIG. 3 are also applied. That is, the distance power measurement point mark 7 in FIG. 1, the standard fitting point mark 8,
A center circle mark 9 for near vision, a lens display mark 10 for left and right eyes, a left and right reference mark 11, and the like are displayed. However, the distance power measurement point mark 7 and the standard fitting point mark 8 do not necessarily have to be displayed, and if they are displayed, they are displayed as small dots, as shown in Fig. 1. is preferable.

[Effects] The present invention's aid with a fitting mark can be easily used when fitting eyeglass frames or measuring power, including when considering individual differences in fitting points. This has the effect of completely eliminating the need for tools such as special marks. Furthermore, by using the aiding device with fitting marks of the present invention, it is possible to accurately and easily determine the optimal fitting position of the wearer, and furthermore, it is also recognized that corrections can be made in the same manner.

In particular, since conventional marks can be added, even a wearer with a circular lens before being inserted into a frame can confirm the time between wearing the glasses.

The aid with a fitting mark of the present invention is not limited to progressive multifocal lenses, but also has the feature that it can be applied to almost all eyeglass lenses, such as other single vision lenses and multifocal lenses. be.
