BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a spectacle lens for correcting visual acuity, and more particularly, to a spectacle lens for correcting visual acuity by artificially limiting a light amount incident through a pinhole by forming a plurality of pinholes in a spectacle lens .

In general, vision correction glasses are known as one of the most representative methods for correcting visual acuity.

As shown in FIG. 1, a plurality of pinholes 10 are punctured in a spectacle lens 1 made of opaque plastic to a certain size, and the visual acuity is corrected using a pinhole effect.

As shown in FIG. 2, the pinhole effect artificially limits the amount of light incident through the pinhole 10, so that the image formed by the rays passing through the pinhole 10 out of the images formed by the rays entering at various positions, Thereby significantly reducing the degree of cloudiness of the image, thereby improving myopia and nourishment.

Accordingly, the user finds one pinhole 10 for each spectacle lens 1 among a plurality of pinholes 10 formed on both spectacle lenses 1, and focuses through the two holes to recognize the object.

However, in the conventional eyeglasses for correcting vision, light rays incident on the pinhole 10 in a tilted state from the light rays incident on the pinhole 10 pass through the inner wall surface of the pinhole 10 11, the image is formed at a position outside the position at which the image is formed, and the focus is blurred.

In addition, since the inner wall surface 11 of the pinhole 10 is formed of a smooth flat surface, the light rays passing through the pinhole 10 are reflected, and the focus is further blurred, and glare is caused, which causes a great adverse effect on the visual acuity.

In addition, since a large amount of unnecessary light rays are introduced into the eyes through other pinholes 10 formed at a position deviated from the pupil, the dark effect of the darkening can not be remarkably reduced and the glare phenomenon is further increased.

In addition, since a plurality of pinholes are formed, light rays are led in different directions through the plurality of pinholes, so that the focus is blurred as the pinholes overlap, resulting in a problem that the visual improvement effect is greatly reduced.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the problems described above, and it is an object of the present invention to provide an image forming apparatus and an image forming apparatus which prevent a light beam passing through a pinhole from being reflected on an inner wall surface of a pinhole, The present invention has been made in view of the above problems.

In order to achieve the above object, the present invention provides a pinhole spectacle for visual correction having a spectacle lens which is colored and has a plurality of pinholes formed therein for shielding external light rays, wherein light rays passing through the pinhole are reflected on the inner circumferential surface of the pinhole A concavity and convexity are formed.

In addition, a tapered portion may be formed at the outer end of the pinhole to block light incident on the pinhole from outside into the pinhole.

It is preferable that the pinhole is composed of a single first pinhole corresponding to the center of the pupil and six second pinholes formed at intervals of 60 degrees so as to be positioned at the same radius with respect to the first pinhole.

The pinhole may include a single third pinhole corresponding to the center of the pupil, a single fourth pinhole formed to be horizontally spaced apart from the third pinhole, Five fifth pinholes shared by the fourth pinholes so as to be positioned at the same angular intervals and spaced at intervals of 60 degrees while sharing the fifth pinhole to be positioned at the same radius as the third pinhole about the fourth pinhole And may be formed of three sixth pin holes formed in a standing manner.

On the other hand, auxiliary pinholes may be formed on both sides and upper portions of the spectacle lens, respectively, located outside the third to sixth pinholes.

In this case, the auxiliary pinhole may include a first horizontal line passing through the center between the third pinhole and the fifth pinholes located above the third pinhole, and a second horizontal line passing through the third pinhole and the fifth pinhole located below the third pinhole A pair of left auxiliary pinholes located on the left side of the third pinhole formed so as to face vertically on a second horizontal line passing through the center, and a pair of left auxiliary pinholes located on the left side of the third pinhole passing through the center between the third pinhole and the fifth pinholes located above the third pinhole A pair of right auxiliary pinholes located on the right side of a third pinhole formed so as to face vertically on a second horizontal line passing through a center between one horizontal line and the third pinhole and the fifth pinhole located under the third pinhole, And an upper auxiliary pin hole formed to face horizontally on a pair of vertical lines passing through the third pinhole and the fourth pinhole.

According to the present invention configured as described above, since the concave and convex portions are formed on the inner circumferential surface of the pinhole, reflection of light rays passing through the pinhole is suppressed, so that a clear image is formed and the glare is improved.

According to the present invention, the pinhole is composed of a single first pinhole corresponding to the center of the pupil, and six second pinholes formed at intervals of 60 degrees so as to be positioned on the same radius with respect to the first pinhole, By significantly reducing the number of pinholes, it is possible to maximize the effect of darkness by preventing the light from being introduced at positions out of the pupil, thereby further enhancing the focusing power on objects, and to suppress the glare phenomenon as much as possible, Since the same amount of light enters in one direction, the pinholes do not overlap each other, and a very clear image is formed, thereby effecting effective correction of the visual acuity.

According to another aspect of the present invention, there is provided an image forming apparatus, comprising: a pinhole having a single third pinhole corresponding to the center of a pupil, a single fourth pinhole formed horizontally spaced apart from the third pinhole, Five fifth pinholes shared by the fourth pinholes so as to be positioned at a regular interval and spaced apart by 60 degrees with the fifth pinholes sharing the fifth pinhole so as to be positioned at the same radius as the third pinhole about the fourth pinhole The sixth pinhole is formed so that a very clear image is formed so that the effective correction of the visual acuity can be performed and at the same time the focus can be adjusted smoothly even if the distance between the eyes or the pupil is different.

In addition, when auxiliary pinholes are formed on the outer side of the third pinhole to the sixth pinhole on the upper and both side portions of the spectacle lens, a wider field of view is secured to the user in the upper, left, and right directions, The pinhole is formed only at the center of the lens barrel, so that it is possible to improve the inconvenience caused by the limitation of the field of view.

The features and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. Prior to this, terms and words used in the present specification and claims are to be interpreted in accordance with the technical idea of the present invention based on the principle that the inventor can properly define the concept of the term in order to explain his invention in the best way. It must be interpreted in terms of meaning and concept.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. The same reference numerals are used for the same components, and only the different portions are described for the sake of clarity.

3 to 5, the pinhole glasses 100 for correcting vision of the present invention includes a spectacle frame 110 and a spectacle lens 120 having a plurality of pinholes 130 sandwiched between the spectacle frames 110 .

The inner wall surface of the pinhole 130 is provided with a concave and convex portion 132 for making the inner wall surface of the pinhole 130 roughened to suppress reflection of light rays passing through the pinhole 130 into the pupil.

The concave and convex portions 132 are not incident parallel to the pinhole 130 among the light beams incident on the pinhole 130 but are interfered with the incident light beams that are obliquely incident. As a result, the reflected light beams interfering with the concave-convex portion 132 are scattered in the concave-convex portion 132 and can not escape from the pinhole 130, and disappear.

The concavo-convex part 132 is formed by spraying polish yarn with high hardness such as gold or steel powder or glass powder with strong pressure using the sand blast to the end of the pinhole 130 and passing the pinhole 130 through the pinhole 130 To form a scratch on the inner wall surface of the substrate.

In this way, when the reflection light beams incline obliquely without being incident parallel to the pinhole 130 disappear, the image is always formed only by the rays passing through the pinhole 130 in parallel, so that the image is clearly formed and the reflection of the light ray in the pinhole 130 The glare is improved.

Meanwhile, it is preferable that a tapered portion 131 is formed at the inner end of the pinhole 130.

The tapered portion 131 may cause the flow of the polishing yarn passing through the pinhole 130 to be irregularly guided through the tapered portion 131 in the process of manufacturing the pinhole 130, So that finer and uniform irregularities 132 can be formed on the entire wall surface.

Particularly, the tapered portion 131 minimizes the glare by changing the angle of reflection so that the tapered portion 131 does not disappear through the concave and convex portion 132 but is reflected outside the pupil with respect to a part of the reflected light rays passing through the inside of the pinhole 130.

According to the present invention, the pinholes 130 are disposed at the center of the spectacle lens 120 so that the pinholes 130 can be positioned in the user's pupil when the spectacles are worn.

The pinholes 130 include a first pinhole 130a corresponding to the center of the pupil and six second pinholes 130a spaced apart by 60 degrees so as to be positioned on the same radius d as the center of the first pinhole 130a. (130b).

In this case, the diameters of the pinholes 130 are each 1 mm smaller than the minimum size of the pupil, and the second pinhole 130b is formed to have a diameter of 5 mm from the first pinhole 130a so as not to exceed 6 mm, So as to be positioned at a normal position.

In this case, there are six regular triangular areas consisting of two second pinholes 130b sharing the first pinhole 130a. Due to the characteristics of a regular triangle, the intervals d of the pinholes 130 forming a regular triangular area are all 5 mm.

Therefore, when the pupil is the minimum size, the image is formed through the rays entering the pupil through the pinhole on one side. When the pupil is maximized, when the pupil is moved to the center of the regular triangle area, Since the image is formed through the rays, the user does not see the pinholes overlapping each other, and a very clear image is formed so that the effective correction of the eyesight is performed.

In addition, since the pinholes 130 are disposed only at the center of the spectacle lens 120, the rays are not introduced at the positions out of the pupil, maximizing the dark effect, thereby increasing the focusing power on the objects and also suppressing the glare phenomenon as much as possible .

6, the pinhole 130 may include a third pinhole 130c corresponding to the center of the pupil, and a second pinhole 130b formed to be spaced apart from the third pinhole 130c in the horizontal direction, as shown in FIG. 6, according to another embodiment of the present invention. A fourth pinhole 130d and a fifth pinhole 130d sharing the fourth pinhole 130d so as to be positioned at the same radius as the fourth pinhole 130d with respect to the third pinhole 130c, Three sixth pinholes 130e are formed at intervals of 60 占 with the fifth pinhole 130e sharing the fifth pinhole 130e so as to be positioned at the same radius as the third pinhole 130c around the fourth pinhole 130d. And 130f.

In this case, the diameter of the pinholes 130 is 1 mm smaller than the minimum size of the pupil, and the fourth pinhole 130d has a radius of 5 mm from the third pinhole 130c so as not to exceed 6 mm, (d1). The fifth pinhole 130e is also positioned on the radius d1 of 5 mm from the third pinhole 130c and the sixth pinhole 130f is also positioned on the 5 mm radius from the fourth pinhole 130d. .

In this way, the four-directional equilateral triangular areas consisting of the two fifth pinholes 130e sharing the third pinhole 130c, the third pinhole 130c, the fourth pinhole 130d and the fifth pinhole 130e Direction equilateral triangular regions exist. Due to the characteristics of the equilateral triangle, the intervals d1 of the pinholes 130 forming the regular triangular region are all equal to 5 mm.

Therefore, when the pupil is the minimum size, the image is formed through the light beam entering the pupil through the pinhole on one side. When the pupil is maximized, when the pupil is moved to the center of the regular triangle area, The image is formed through the incoming rays so that the user can obtain a very clear image and effective correction of the visual acuity can be obtained and the center of the pupil can be positioned in the third pinhole 130c or the fourth pinhole 130d, So that a user with a different distance between the eyes or the pupil can smoothly adjust the focus.

As shown in FIG. 7, on both sides of the spectacle lens 120 and on the upper portion of the spectacle lens 120, an auxiliary (not shown) positioned outside the third pinhole 130c to the sixth pinhole 130f may be provided as another embodiment of the present invention. The pinholes 130e, 130h, 130i may be further formed. The auxiliary pinholes 130e, 130h, and 130i help the user to see a wider view in the left, right, and upper directions. Therefore, when the auxiliary pinhole is further formed, a pinhole is formed only in the center of the spectacle lens 120, thereby making it possible to improve the inconvenience in use caused by the limited visual field.

In this case, the auxiliary pinhole has a first horizontal line L1 and a third pinhole 130c passing through the center between the third pinhole 130c and the fifth pinhole 130e positioned on the third pinhole 130c, And the third pinhole 130c formed to face vertically on the second horizontal line L2 passing through the center between the fifth pinhole 130e located below the third pinhole 130c A first horizontal line L1 and a third pinhole 130c passing through the center between the left auxiliary pinhole 130g and the fifth pinhole 130e positioned above the third pinhole 130c and the third pinhole 130c, And a third pinhole 130c formed to face vertically on a second horizontal line L2 passing through the center between the first pinhole 130c and the fifth pinhole 130e located below the third pinhole 130c, And an upper auxiliary pinhole 130i formed to face horizontally on a pair of vertical lines L3 extending from the third pinhole 130c and the fourth pinhole 130d. Can.

The left auxiliary pinhole 130g and the right auxiliary pinhole 130h are formed at the same distance apart from the center between the third pinhole 130c and the fourth pinhole 130d.

The left auxiliary pinhole 130g, the right auxiliary pinhole 130h and the upper auxiliary pinhole 130i are respectively connected to the third pinhole 130c and the fourth pinhole 130f from the adjacent fifth pinhole 130e and sixth pinhole 130f, Is formed at a position which is not more than twice or more than twice the distance between the electrodes 130d.

This is because the left auxiliary pinhole 130g, the right auxiliary pinhole 130h and the upper auxiliary pinhole 130i are separated from the adjacent fifth pinhole 130e and the sixth pinhole 130f by a plurality of repetitive tests, When the distance between the third pinhole 130c and the fourth pinhole 130d is more than twice the distance between the third pinhole 130c and the fourth pinhole 130d, As the motion of the pupil for viewing the pupil increases, the concentration of the pupil is remarkably reduced and inconvenience is caused.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be takeners of ordinary skill in the art, And such variations are within the scope of the present invention.
