Description

Eyeglasses for vision correction using pinhole effect and eyeglasses for eyeglasses made by applying the glasses

The present invention relates to a spectacle lens for correcting visual acuity, and by using a luminosity factor curve of the retinal cells of the eye, by varying the transmittance for each wavelength in the spectacle lens, the visual acuity correction is made to see the object more clearly. The present invention relates to a spectacle correcting spectacle lens using a pinhole effect and to a spectacle correcting spectacles manufactured by applying the spectacle lens.

The eye is an important part of our body.

The eye can be an important input means for recognizing surrounding information. The function of the eye is to recognize the color, shape, and distance of the object.

The human eye is a kind of convex lens-like structure. When an object is refracted by the lens and a reverse phase is formed in the retina, the reverse phase is converted to normal by the optic nerve crossing while the reverse phase is transmitted to the cerebrum through the optic nerve.

The lens becomes thick due to contraction and relaxation of the connected ciliary body and becomes thinner when viewed from afar, so that the object is precisely formed on the retina, and the deformation of the lens occurs as the lifestyle and age grow. This prevents the camera from focusing on the correct location of the retina.

At this time, according to the position of the image formed on the retina, it is called vision, primitive, or myopia. It looks blurry.

When the eyes are born, they are born primitive at first, are aligned on time as they grow up, and are transferred to myopia by genetic and environmental factors. Basically, the genetic factors, the influence of the surrounding environment, the habit of use, and Over time, the eyesight of the eye decreases.

Various methods for correcting such vision have been suggested for a long time, and recently, various instruments have been used to correct vision. A typical example is vision correction glasses using a pinhole effect.

As shown in FIG. 1, the spectacle correcting spectacle lens drills a plurality of pin holes of 0.7 mm to 0.9 mm in the convex plate curved surface, and blue, green, and the like on the surface of the convex plate curved surface. It is coloring.

Such spectacle lenses are called micro-hole glasses or pin-hole glasses because the needle holes are drilled.

Micro-hole glasses are designed to correct vision using the pinhole effect, which allows people with refractive errors such as myopia, hyperopia, astigmatism, and presbyopia to see distant (myopia) or near objects (presbyopia). .

2 and 3 are views for explaining the technical background of the micro-hole glasses. In FIG. 2, light is incident in a general state, and in FIG. 3, the pinhole is partially blocked by the blocking film. It represents the case where light is incident through.

The technical background of such a micro-hole glasses is as follows.

In the case of myopic eyes, the image is generated in the front as shown in FIG. Therefore, the image formed on the retina is blurry in which several images overlap.

On the other hand, when incident through the pinhole, as shown in Figure 3, the incident beam 1 and 3 is blocked by the blocking film, the incident beam passes only two times to form only one image in the image position, eventually There is only one image in the retina.

Although three incident beams are described here, in reality, since there are many incident beams, light passing through the pinhole is not one, so that a slightly overlapping image may occur, which means that the overlap is significantly reduced. will be

That is, due to the blocking effect of the beam around the optical axis of the incident beam, the blurring degree of the image to the image formed only by the light rays passing through the region on the optical axis with less aberration is remarkably reduced. It is artificially limited so that you can see a distant (myopia) or near object (presbyopia).

In other words, light from various positions creates images in various positions. If the light is blocked through the pinhole made of small holes, such as the amount of light is reduced when the eye is frowned, By blocking part of the image, light passing through the same path thus forms a consistent image regardless of the distance of the screen, which is the principle of micro-hole glasses.

As illustrated in FIG. 1, a user finds one pin hole for each lens among a plurality of pin holes formed in both lenses, and focuses through two holes to see an external object.

In this way, by constantly looking at the object to focus, by exercising the eye muscles to improve the resilience of the ciliary muscles and the lens.

However, while the distance between the human eye and the eyes is different for each person, the distance between the pinholes is fixed at about 2 mm.

Therefore, even when one of the pin holes is selected, the hole distances d1 and d2 between the two lenses appear to be constant, so that accurate focusing is not achieved, and thus, it is difficult to effectively adjust visual acuity.

In the present invention, in the construction of a plurality of pinholes in consideration of the difference between the distance between the human eye and the eyes of each person, the positions of the pinholes of the left and right eyeglass lenses are differently designed according to each position, and thus each position of the vision correcting glasses. By varying the amount of light of the external beam incident upon the user, the functional correction of the vision correction glasses due to the distance between the human eye and the eyes of the human eye can be minimized so that the user can focus more effectively when focusing. It is an object of the present invention to provide a vision correcting lens using a pinhole effect, and a vision correcting glasses using the lens.

Eyeglasses for correcting vision using the pinhole effect according to the present invention has a constant curved surface, it is made of a colored panel 10 to block the external beam, the external beam can be limitedly incident on the panel 10 A plurality of pin holes 20 are formed in a perforated shape, and the pin holes 20 are arranged in a trapezoidal shape in which an inclined line having a predetermined angle θ from a vertical line is arranged in parallel from left and right sides. do.

As described above, the spectacle lens for correcting eyesight of the present invention is designed such that the distance between the pinholes of the left and right lenses is different when the glasses are manufactured, and the spacing between the pinholes in the spectacle lenses is different from each other, so that the human eye, the pupil It is possible to minimize the functional deterioration of vision correction glasses due to the distance between them, and it is possible to subdivide and configure the focus for various distances between different eyes according to the person. Since it can provide a clear view and the vision correction effect is improved.

FIG. 4 is a view illustrating glasses for applying vision correction glasses using the pinhole effect of the present invention, and FIGS. 5A to 5C are views illustrating an embodiment of a pinhole arrangement of the glasses for correcting vision.

Eyeglasses for vision correction using the pinhole effect of the present invention,

It has a constant curved surface and is made of colored panels 10 for blocking the external beam, and a plurality of pin holes 20 are formed in a perforated form so that the external beam can be incident to the panel 10 in a limited manner. under,

The predetermined angle from the vertical line so that the distances d1, d2, d3, and d4 of each of the incident areas of the left and right panels 10, i.e., the pinholes 20 at the same position from the left and right ends of the glasses, are different from each other. The pinholes 20 are arranged in a trapezoidal shape in which the inclined lines constituting (θ) are arranged side by side from the left and right sides.

The panel 10 is formed in a convex plate shape in the form of a lens, and forms a blocking area for blocking light in a specific spectrum band.

Looking at the luminosity factor curve for the human eye, it can be seen that the visibility is most sensitive to the wavelength of yellow light. That is, it is known to recognize the outline of the object by the yellow wavelength when the external object is seen by the eye, and recognize the color of the object by the light of the other wavelength.

Therefore, the key point of the pinhole effect is to allow a limited blocking of light of the yellow system that recognizes the outline of the object so that the outline of the object can be recognized more clearly.

Therefore, in consideration of the above, the blocking region is formed by coloring with a color such as blue or green on the panel to block the light of the yellow system and to transmit other light.

On the panel 10 having a plate-shaped curved surface as described above, a plurality of pin holes 20 are drilled in order to allow the external beam to be incident.

In general, the inner diameter of the pin hole is about 0.7mm to 0.9mm.

At this time, as shown in Figure 4, the vertical line so that the distance (d1, d2, d3, d4) between the pin holes 20 for each position of the incident area contrasted on the vertical line of the left and right panels 10 appear differently It is arranged in a trapezoid with an inclined line that forms a predetermined angle θ from the image.
That is, the pin holes 20 are arranged while forming an inclined line forming an angle θ from the vertical line, so that the distance d1 between the pin holes 20 located at the same position from the left and right ends of the left and right panels 10. , d2, d3, d4) become shorter from the top, that is, the length is d4>d3>d2> d1.

In this embodiment, the upper side is formed in a trapezoidal shape having an inclined line so as to be formed in the lower side, but the upper side line can be formed in a trapezoidal form having an inclined line so that the lower side line is formed in the lower, which is either upper or lower A trapezoidal arrangement with inclined lines is possible from one side.
That is, the present embodiment is configured such that the upper side is configured to have a lower arrangement from the outer side and the inner side of the spectacle lens to the lower side, but the upper side is configured to the upper side and narrows from the outer side and the inner side to the upper side. It is possible to configure the pinhole 20 to have a losing arrangement.
5A to 5C illustrate another embodiment of the arrangement of the pinholes 20. These embodiments, when manufactured with glasses, varying and subdividing the distance between the pinholes 20 of the left and right panels 10 to present more various maximum number of focal points in the lens of the same area, thereby providing various glaucoma. Allows the user to see well and find the pinhole 20 that is accurate in focus.

In FIG. 5A, the inclination lines L1, L2, L3, L4, L5, and L6 are formed at a predetermined angle from the vertical line, and in setting the arrangement angle, the inclination line in which the adjacent pinholes 20 are arranged. When the angle difference from (L1, L2, L3, L4, L5, L6) is different from θ1> θ2> θ3> θ4> θ5, when the glasses are manufactured, the arrangement of the pinholes 20 is symmetrically In addition, the distances d1 and d2 between the pinholes 20 in the panel 10 may be changed, as well as the distance between the pinholes 20 at the same position from the left and right sides of the panel 10. This allows for more effective focusing.

FIG. 5B shows the arrangement of the pinholes in an arc-like arrangement. FIG. 5C shows the distance between the pinholes of the spectacle lens by arranging the pinholes at different angles (θ1> θ2) from one side from the center. Can be different.
At this time, the angle of θ1 is a numerical value that can give the basic function and effect of the minimum correction lens to the user with a variety of glacial distance, preferably 45 ° or less, most preferably 30 ° or less.
As θ1 becomes smaller in the range of 30 degrees or less, the distance between the imaginary lines drawn from each pin hole 20 decreases further in the lower part of the drawing, so that each pin hole 20 is densely packed in a horizontal line. By maximizing the number of pinholes presenting various focuses on the area of the user's area, the user can find the pinhole arrays arranged in the horizontal direction with fine focus. In general, the distance between the virtual lines drawn downward in each pin hole in the conventional correction lens is about 1.5mm, but in the correction lens of the present invention, the pinhole can be further reduced to about 0.5mm.

As described above, the arrangement of the pinholes 20 is not limited as in the present embodiment, and as described above, in the arrangement of the inclined lines in the form of circular arcs, the distance between the teeth of 0.1 mm to 10 mm, the user's pupil It is possible to design an adjustable arrangement while varying the tilt angle and curvature continuously in consideration of the position.

When constructing a vision correcting glasses by applying a spectacle lens having a pinhole array as described above to form a pinhole array symmetrically with respect to the two spectacle lenses so that the inclined lines or two arcs facing each other or facing in the opposite direction The distance between the pinholes between the spectacle lenses is set differently.

As described in the principle of vision correction glasses using the pinhole effect, the vision correction glasses using the pinhole effect blocks the yellow light and injects an external beam incident according to the position of each lens to control the user's focus. In order to obtain a clearer image to be achieved, the amount of light of the external beam incident according to the position of each lens is a very important factor in focusing the user.

Therefore, as the amount of light of the external beam incident upon the eyeglasses to which the spectacle lens is designed is applied varies, the functional deterioration of the eyeglasses due to the distance between the human eye and the pupil can be minimized. .

On the other hand, as another embodiment of the present invention, unlike the above-described embodiment consisting of a curved plate-shaped lens, the vision correction lens can be configured by adhering a thin film having a pinhole formed on the upper surface of the lens.

Such another embodiment of the present invention,

The thin film includes a lens unit and a thin film, and the thin film has a plurality of pin holes formed therein, and the pin holes are arranged so that the distances between the pin holes of the left and right lens parts are different from each other.

The lens unit is a general spectacle lens, but may be configured as a spectacle lens that can be configured a slight degree if there is no degree.

The thin film is coated or colored with a specific material so as to block light of a yellow system, and a plurality of pin holes are arranged to form an incident region.

In this case, the pin holes may be arranged as described in the above embodiments as shown in FIGS. 4 and 5A to 5C.

In addition, the thin film may be formed by coating the lens unit, and may also be configured in the form of an adhesive film.

In the case of an adhesive film, it can be used by adhering to a general spectacle lens.
In addition, apart from the thin film, in order to protect the eyes of the wearer of vision correction glasses according to the present invention, it is preferable that UV, infrared or electromagnetic wave blocking films are treated by the lens unit by coating, coating, spraying or dipping. .

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
