Description

  The present invention relates to eyeglasses. In particular, the present invention relates to spectacles that allow the user himself to easily check whether the pupil center matches the optical center of the lens.

Glasses are widely used as medical devices for correcting vision, and there are various types of glasses such as for myopia, for hyperopia, for astigmatism, for presbyopia, for both near and near, depending on the eye condition of the user. ing.
Since the eyeglasses assist the focus adjustment function of the eyes with a convex lens or a concave lens, it is necessary to select an appropriate lens for the user's eyes and appropriately adjust the power, position, inclination, etc. of the lens, If the adjustment is not appropriate, it is not only difficult to see, but also causes symptoms such as eye strain and headache.

In general, eyeglasses that fit the eyes are (i) the lens power is matched, (ii) the lens is tilted properly, (iii) the distance between the eye and the lens is 12 mm, (iv) use The distance between the pupils (PD) of the person and the distance between the optical centers of the left and right lenses match, and (v) the object can be viewed through the optical center (OC) of the lens. Is supposed to be done. (See Figure 5)
Therefore, spectacles prescriptions corresponding to blueprints for spectacles contain information such as distance or near vision, lens power, astigmatism power, astigmatism axis, oblique position, base, and interpupillary distance (PD). Based on these information and the frame shape, the lenses are selected and processed, so that they are made to order for each individual user.

  Furthermore, in most eyeglass stores, when handing over the finished eyeglasses to the user, make sure that the distance and position between the user's eyes and the lens are properly adjusted while wearing the eyeglasses. Fine adjustments and readjustments are performed as necessary, and are provided to the user after finally confirming that the glasses are suitable for the user's eyes.

However, even eyeglasses made on the basis of a prescription for eyeglasses as described above seemed to be suitable for eyes at the time of purchase or delivery, There are a lot of people who are suffering from such troubles as symptom such as being difficult to see near or near, or appearing distorted.
Many of these troubles are not adjusted to allow the object to be seen through the optical center (OC) of the lens (v) of the eyeglass requirements described above. This is because the pupil center (PC) of the lens does not coincide with the optical center (OC) of the lens.

  The above-mentioned spectacle prescription contains information necessary for adjustment that satisfies the requirements (i) to (iv) of eyeglasses suitable for the eye, but information necessary for adjustment that satisfies the requirement (v) is described. Therefore, the spectacles engineer produces the spectacles by incorporating the lens so that the optical center (OC) of the lens is positioned at the average height of the frame. In this way, if it was made ignoring the position of the user's pupil center (PC), it is unlikely that it will be suitable glasses that meet the requirement (v), and troubles may occur due to continued use. It must be natural.

The object can be seen through the optical center (OC) of the lens in (v) above, that is, the state where the user's pupil center (PC) and the optical center (OC) of the lens coincide with each other. As shown in FIG. 6, when the object is viewed through the lens, the optical center (OC) of the lens is located on the user's visual axis (Ax) indicated by a broken line in FIG. .
FIG. 6 (a) shows a case in which an object in front of a person is seen, such as a personal computer screen or a television, while wearing glasses. At this time, the user sees the object through a position higher than the optical center (OC) of the lens, and the pupil center (PC) of the user and the optical center (OC) of the lens do not coincide with each other. Is shifted by a distance d in the vertical direction.

Due to the deviation of the distance d, if the lens power is P, a prism represented by d × P is produced, and the image of the object appears to be displaced from the actual position. In order to correct this displacement, the six extraocular muscles attached to the eyeballs are complicatedly expanded and contracted, resulting in a large burden on the eyes, resulting in various symptoms such as eye strain and headache. Become.
FIG. 6 (b) shows a case where an object positioned obliquely below such as a hand or a book on a desk is viewed with the same glasses worn. At this time, the user sees the object through the optical center (OC) of the lens, and the pupil center (PC) of the user and the optical center (OC) of the lens coincide. Therefore, the prism as shown in FIG. 6A does not occur, and it can be used comfortably.

In this way, even with the same glasses, they are not suitable for personal computer operation or TV viewing, but may be suitable for reading and writing. That is, the pupil center (PC) of the user is not constant for each person, but changes depending on the purpose of use (position of the object). Therefore, the glasses need to be adjusted according to the user's purpose of use and lifestyle.
The problem of eyeglasses that are not suitable for eyes is particularly noticeable in ready-made glasses represented by reading glasses. Since the pre-made spectacles are designed based on an average value, not only the above-mentioned discrepancy between the pupil center (PC) and the optical center (OC) of the lens, but also the distance between the pupils (PD), eye This is because there is a high possibility that the eyeglasses do not satisfy the requirements (ii) to (iv) of eyeglasses suitable for eyes such as the lens distance and the lens tilt angle.

Furthermore, because the lens is transparent, it is difficult for the user himself to check whether the pupillary distance (PD) and optical center (OC) are correct when purchasing pre-made eyeglasses. The present situation is that the wearer tries on the pre-made glasses arranged from one end and intuitively selects the one that looks best. With this selection method, there is a fear that the optic nerve and eye muscles may become tired and judgment may be blunted, and it is not easy to select ready-made glasses suitable for oneself.
The present invention has been made in view of the above circumstances, and it is an object of the present invention to make it possible for a user to easily confirm whether the eyeglass is suitable for his / her eyes when purchasing the eyeglass. . Furthermore, another problem is that the user himself can easily check whether there is any deviation between the pupil center and the optical center of the lens due to frame distortion, etc. To do.

(1) The spectacles of the invention according to claim 1 are: “The same figure having a transparent see-through window at the center is shown on the left and right lens surfaces,
The figure is expressed in the same posture so that the optical center of each lens coincides with the center of the see-through window ”.
According to this, when the glasses of the present invention are worn, if the object cannot be seen through the left and right figure perspective windows, or if the user feels uncomfortable or burdensome when trying to see it, the center of the pupil And the optical center of the lens can be determined to be large. Further, even when the object can be seen through the fluoroscopic window, even when an image composed of two figures appears on the object, it is determined that there is a deviation between the pupil center and the optical center of the lens. can do. When the object is viewed through the fluoroscopic window, if an image in which left and right figures overlap each other appears on the object, it is determined that the pupil center coincides with the optical center. Can do.

Thus, the user himself / herself determines whether the pupil center and the optical center of the lens coincide with each other by confirming an image appearing on the object when the object is viewed through the perspective window of the figure. Can do.
Here, the object is selected according to the purpose of use of the user's glasses, and if it is mainly used for reading, it is sufficient to check the image that appears on the paper when reading the book, Moreover, if it is used for driving a car or watching TV, it is only necessary to confirm an image that appears on the wall surface when looking at a wall or an article several meters ahead in a posture facing the front.
The figure may be a general figure such as a circle, a triangle, or a rectangle, a heart shape, or a star shape, as long as it can be easily confirmed whether the left and right figures overlap each other. Further, as long as the image appearing on the object can be recognized, the color of the figure may be not only an opaque color but also a translucent color.

(2) The glasses of the invention according to claim 2 are: “The figure is set so that its diameter is 2 mm to 30 mm, the see-through window is circular, and its diameter is 1 mm to 5 mm. It is characterized by ".
According to this, when trying to view an object through the fluoroscopic window, the visual axis of the user is not obstructed by the graphic, and the entire graphic naturally enters the user's field of view without difficulty. The shape of the image can be reliably determined without missing a part of the image appearing on the symmetrical object. The diameter of the figure is preferably 6 mm to 12 mm, and most preferably about 8 mm.

(3) The glasses of the invention according to claim 3 are: “The figure is drawn on a seal that is detachably attached to left and right lenses, and the transparent window is made of a transparent sealing material or the sealing material. It consists of a hole formed by punching into a predetermined shape ”.
According to this, it can be set as the spectacles which can confirm whether a user's pupil center and the optical center of a lens correspond by sticking a sticker on the optical center of each lens of spectacles. Moreover, it can use as normal spectacles by peeling the said seal | sticker.

(4) The glasses of the invention according to claim 4 are characterized in that “the figure is a ring having a band width of 1 mm to 3 mm”.
According to this, by forming a simple circular shape with a narrow band width, it is possible to accurately determine the shape of the image appearing on the object and the slight misalignment of the overlapping left and right figures.

(5) The glasses of the invention according to claim 5 are “ready reading glasses”.
According to this, when trying on the reading glasses, the user himself / herself can easily determine whether or not he / she is in the eyes by checking the image appearing on the object.
(6) The seal of the invention according to claim 6 is “a small seal on which a figure having a transparent window formed transparent or stamped at the center is drawn,
The figure is characterized in that an auxiliary line orthogonal to the center of the fluoroscopic window is drawn from the outer peripheral edge of the fluoroscopic window toward the outside in the radial direction.
According to this, by adjusting the optical center of the lens to be located on the extension of the auxiliary line, the seal can be easily attached to an appropriate attachment position of each lens. Further, if the auxiliary line is used, it is easy to stick the sticker so that the figure has the same posture on the left and right lenses.

As described above, according to the first aspect of the invention, the same figure having a transparent see-through window at the center on the surfaces of the left and right lenses is represented so as to coincide with the optical center of the see-through window and the left and right lenses. Therefore, just looking at the object through the fluoroscopic window with the glasses attached, whether the optical center of the lens is located on the visual axis, that is, whether the optical center of the pupil coincides with the optical center of the lens Since the user can determine whether or not the glasses are suitable for his / her eyes when purchasing the ready-made glasses or delivering the ordered glasses, the user can easily and clearly confirm whether the glasses are suitable for his eyes.
In addition, by representing the figure at the optical center of the glasses in use, the user himself can easily check whether there is any deviation between the pupil center and the optical center of the lens. Therefore, the frame distortion and the like can be periodically corrected to always maintain comfortable glasses.

  According to the second aspect of the present invention, the shape of the image appearing on the object can be ensured by making the see-through window a circle having a diameter of 1 mm to 5 mm so that the figure has a diameter of 2 mm to 30 mm. Since the determination can be made, it is possible to select the ready-made glasses that match the eyes with higher accuracy, check the finish of the ordered glasses, or check the glasses in use.

According to the third aspect of the present invention, since the figure is drawn on the sticker that is detachably attached, the user himself / herself has the pupil center and the optical center only by attaching the sticker to the glasses. Since it can be set as the spectacles which can judge whether it corresponds, the manufacture of the spectacles of this invention is easy. It is also convenient in that it can be used normally if the seal is peeled off.
According to the invention according to claim 4, since the ring-shaped figure having a band width of 1 mm to 3 mm can be used to accurately determine the shape of the image that appears on the object, higher accuracy is achieved. It is possible to select the ready-made glasses suitable for the eyes, confirm the finish of the ordered glasses, or check the glasses in use.

According to the invention according to claim 5, since the user can easily confirm whether or not the reading glasses are suitable for eyes by trying on the reading glasses, the use of the ready-made reading glasses that are mass-produced. Can minimize eye problems.
According to the sixth aspect of the present invention, since the auxiliary line orthogonal to the center of the fluoroscopic window is drawn from the outer peripheral edge of the fluoroscopic window toward the outer side in the radial direction, the seal is made suitable for the right and left lenses. Since it can be reliably and easily attached to the attachment position, the glasses according to any one of claims 1 to 5 can be easily produced.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
An example of glasses according to an embodiment of the present invention is shown in FIG.
This is a ready-made reading glasses made based on an average numerical value, a metal frame (4), a pair of left and right presbyopia lenses (1) incorporated therein, and the lens (1) It consists of a circular graphic sticker (2) that is detachably attached to the optical center. The figure seal (2) is printed with a ring-like figure (3) in which a circular hole (21) functioning as a see-through window (30) is punched and formed at the center.
As shown in FIG. 2, the figure seal (2) has a ring-like figure (3) colored in translucent orange on a circular transparent seal material (20) and the seal material (20). It is a small seal piece drawn concentrically, and in the figure (3), a cross-shaped auxiliary line (31) perpendicular to the center of the transparent window (30) is drawn in black.

The graphic seal (2) is attached to the surface side of the lens (1) so that the center of the transparent window (30) and the optical center of the lens (1) coincide with each other. Since both (20) and the lens (1) are transparent, the orange figure (3) can be seen from the back side of the lens (1).
In this example, the diameter of the graphic seal (2) is 11 mm, the diameter of the graphic (3) is 8 mm, the diameter of the transparent window (30) and the circular hole (21) is 4 mm, and the graphic (3 ) Is set to 2 mm.

Next, as shown in FIG. 3, an example of a method for determining whether or not the reading glasses are actually worn and matching the user's eyes will be described. In this example, for simplification of explanation, as shown in FIG. 3, it is assumed that the interpupillary distance (PD), which is the requirement (ii) of eyeglasses suitable for eyes, is appropriately adjusted. Will be described.
FIG. 4 (a) shows a case where the character “ku” of the character string displayed on the personal computer screen located in front of the object (5) is viewed as the object (5) with the reading glasses of this example attached.

In this case, even if the object (5) is viewed through the perspective windows (30) of the left and right figures (3), the perspective window (30) is positioned below the visual axis (Ax). Therefore, it is impossible to see through the transparent window (30). In addition, as shown in FIG. 4A, the image (6) to be drawn also appears in such a way that a part of the two figures overlap below the character “ku”.
As a result, when viewing an object (5) located directly in front of a computer screen or the like, there is a large misalignment between the pupil center (PC) and the optical center (OC) of the lens (1), resulting in a prism. Therefore, it can be determined that continuous use is likely to cause various symptoms such as eye strain and headache.

FIG. 4 (b) shows a case where the same reading glasses are viewed as the object (5) in the character string “ku” displayed on the desk document located obliquely below.
When viewing “ku” as the object (5) through the perspective windows (30) of the left and right figures (3), the character “ku” as the object (5) is shown in FIG. 4 (b). As a result, one image (6) in which the left and right figures (3) overlap each other appears on the outer periphery of.
Thus, when viewing an object (5) located obliquely below, such as a document on a desk, the pupil center (PC) and the optical center (OC) of the lens (1) coincide, and the optical center (OC ), The object (5) can be seen, so that it can be determined that it can be comfortably continued.
Here, it is determined whether or not the reading glasses differ only in the height positions of the pupil center (PC) and the optical center (OC), but only the interpupillary distance (PD) is uncertain. Even in an appropriate case, an image (6) composed of two figures is drawn on the object (5) as in FIG. 4 (a).

  Thus, the optical center (OC) of the lens (1) is on the visual axis (Ax) by viewing the object (5) through the perspective window (30) of the figure (3) with the reading glasses attached. The user himself / herself can easily and surely determine whether or not the user's pupil center (PC) matches the optical center (OC) of the lens (1). Therefore, since the user himself can select the reading glasses suitable for his eyes from the reading glasses arranged in the store, it is possible to prevent eye trouble such as eye strain and headache caused by the existing reading glasses.

Further, since the figure (3) is a ring shape having a diameter of 8 mm and a band width of 2 mm, and the diameter of the see-through window (30) is 4 mm, the shape of the image appearing on the object (5) can be accurately determined. Because you can see well, you can select reading glasses that match your eyes with higher accuracy.
In this example, since the peelable graphic sticker (2) is attached to the optical center (OC) of the left and right lenses (1), it is easy to make glasses, and after purchase, The figure sticker (2) can be peeled off and used as ordinary reading glasses.
In addition, since the auxiliary line (31) perpendicular to the center of the fluoroscopic window (30) is drawn on the graphic sticker (2) of this example, the graphic sticker (2) is attached to the optical center of the lens (1). (OC) can be reliably and easily attached.

* Others The glasses of the present invention and the seals used for them are not limited to the above-described embodiments.
In the above example, the figure sticker (2) is attached to the lens (1) of the pre-made reading glasses, but even those that are attached to other pre-made eyeglasses are prepared based on the spectacle prescription. It may be attached to the lens (1) of the ordered eyeglasses. By attaching the graphic sticker (2) to the optical center (OC) of the lens (1) of the order spectacles, it is possible to determine whether or not the spectacles are suitable for the user's eyes when handing over the spectacles. Can be confirmed.

  In addition, it is possible to check whether the pupil center (PC) is coincident with the optical center (OC) of the lens (1) by attaching the graphic sticker (2) to the glasses in use. By regularly inspecting in this way, the deviation between the pupil center (PC) and the optical center (OC) due to distortion of the frame (4) and the like can be found and corrected at an early stage, It is possible to maintain comfortable glasses suitable for the user's eyes.

  In the above example, the figure (3) is printed on a transparent sealing material (20) attached to the surface of the lens (1). It may be expressed directly so as not to be peeled off by printing or the like. In this way, by displaying the figure (3) in an inseparable form as a sample product, it is possible to save the trouble of sticking the figure sticker (2) to each sold product. In addition, it is possible to prevent inconvenience that the graphic sticker (2) is displaced from an appropriate sticking position or peeled off by repeated fitting.

The figure (3) is drawn in a translucent orange color, but when the object (5) is viewed through the perspective window (30) of the figure (3), the figure (3) is above the object (5). As long as the image (6) appearing on the screen can be visually recognized, the coloring of the figure attached to the left and right lenses (1) is different, regardless of whether it is opaque or colored. Also good. For example, if the right lens (1) represents a yellow figure (3) and the left lens (1) represents a blue figure (3), the object ( Since the green image (6) appears on 5) and the overlapping of the left and right figures can be confirmed by the color, the shape of the image (6) can be confirmed easily and reliably.
In the above example, the figure (3) has a ring shape, but may have other shapes such as a triangle, a square, an ellipse, a heart shape, a star shape, and the shape of the see-through window (30). The shape is not limited as long as the object (5) can be seen. However, the shape of the figure (3) is preferably a figure (3) in which the shape of the image (6) can be easily confirmed.

It is a perspective view which shows the spectacles of embodiment of this invention. It is a top view which shows the seal | sticker used for the spectacles of FIG. It is a front view which shows the state which mounted | wore the spectacles of FIG. It is explanatory drawing which shows the fusion figure which consists of a figure on either side which appears when the target object from which a height position differs is seen. It is a front view which shows the state which mounted | wore the conventional spectacles. It is explanatory drawing which shows the relationship between the optical center (OC) of the glasses of FIG. 5, and a pupil center (PC).
