Description

Technical Field

[0001] This invention relates to spectacle lenses for vision correction and eyeglasses including the same, which, when worn, not only minimize visual interference for the user but also provide excellent vision correction. Background Technology

[0002] Among the eyeglasses developed to correct vision problems such as farsightedness, nearsightedness, and astigmatism, pinhole lenses are a representative example. Pinhole lenses have multiple holes of 0.7mm to 0.9mm formed by punching holes in a plate lens. When a user looks at an object through these small holes, the dispersed focus of the lens converges to a single point, creating a pinhole effect that allows for clear vision.

[0003] When users wear glasses that utilize the pinhole effect, the movement of the lens can be activated by light entering through the hole, thus maintaining eye fatigue and health, and thereby restoring vision by relieving optic nerve tension.

[0004] like Figure 1a As shown in part (a), since existing pinhole glasses use lenses with multiple pinholes punched in, therefore, as Figure 1a As shown in section (b), if a user wears pinhole glasses, the user can focus through the pinhole to see the text clearly and correct their vision. However, when a user wears pinhole glasses, because they prioritize seeing the mesh in front of them, there is a problem that they cannot focus on the target immediately and need to concentrate for a specified period of time to focus.

[0005] Furthermore, while excellent clarity can be achieved when wearing existing pinhole glasses, however, as... Figure 1a As shown in part (a), because an obstruction is formed around the lens along the line of sight, and because the remaining area of ​​the lens, except for the pinhole, is also opaque, when wearing pinhole glasses, if the surrounding environment is relatively dark, it becomes difficult for the user to identify the target. Consequently, as the user becomes frustrated, it becomes impossible to wear pinhole glasses for extended periods.

[0006] like Figure 1b As shown in part (a), in another embodiment of the pinhole glasses, there is no shielding around the lens; therefore, compared to Figure 1a The pinhole glasses shown in part (a), while eliminating the user's discomfort, also have other drawbacks. Figure 1b As shown in section (b), open-type pinhole glasses present the problem of users having difficulty seeing text. Consequently, because the effect of constricting the lens through the pinhole is relatively weak, users have difficulty focusing on targets.

[0007] Therefore, unlike the existing pinhole glasses, the present inventors provide a lens capable of preventing a user from feeling bored and quickly focusing on an object to correct vision and glasses including the same. SUMMARY

[0008] PROBLEMS TO BE SOLVED BY THE INVENTION

[0009] An object of the present invention is to provide vision correction glasses and glasses including the same, which can correct vision of a person wearing glasses while minimizing visual field interference of a user in the case of wearing glasses, unlike existing pinhole glasses.

[0010] MEANS FOR SOLVING THE PROBLEMS

[0011] To achieve the above object, the present invention provides vision correction glasses as a transparent lens, including a line formed on the lens to block a part of a visual field of a user, and causing a holographic phenomenon when the user gazes at an object through the lens, so that the line is disposed in space rather than a plane.

[0037] Figure 2 The figure illustrates the appearance of eyeglasses including vision-correcting lenses according to an embodiment of the present invention.

[0038] like Figure 2 As shown, an embodiment of the eyeglasses 100 of the present invention may include: a pair of spectacle lenses 121, 122; and temples 111, 112, which are combined with the spectacle lenses 121, 122 and hung on the user's ears. The temples 111, 112 can be folded toward the spectacle lenses 121, 122, and the temples 111, 112 can be hinged to the spectacle lenses 121, 122.

[0039] In this case, according to one embodiment, the spectacle lenses 121, 122 can be mounted on the frame, at which time the temples 111, 112 can be hinged to the frame.

[0040] Furthermore, a nose pad can be formed so that the aforementioned eyeglass lenses 121, 122 or frames can be placed on the bridge of the user's nose.

[0041] On the other hand, unlike the lenses of existing pinhole glasses, the lenses 121 and 122 of an embodiment of the present invention can be made of a transparent material that allows light to pass through, just like ordinary eyeglass lenses. This minimizes the area of ​​visual obstruction for the user and thus eliminates the discomfort caused by existing pinhole glasses.

[0042] Furthermore, the eyeglass lenses 121 and 122 of one embodiment of the present invention can ensure a wide field of vision through transparent materials, so they can be worn and used even in relatively dark environments.

[0043] At least one line 131, 132 of a specified thickness can be formed on the transparent eyeglass lenses 121, 122. The lines 131, 132 formed on the eyeglass lenses 121, 122 obstruct part of the field of vision of the user looking at the target through the eyeglass lenses 121, 122. When the user looks at the target through the eyeglass lenses 121, 122, a holographic phenomenon can be triggered, so that the aforementioned lines 131, 132 are placed in space rather than on a plane.

[0044] That is, such as Figure 7a and Figure 7b As shown, when a user looks at a target through the spectacle lenses 121 and 122 of an embodiment of the present invention, like a hologram, the lines 131 and 132 formed on the spectacle lenses 121 and 122 appear to float in space, thereby making the area around the lines appear blurry, while the area around the corresponding lines 131 and 132 appears clear in the target that is focused on through the spectacle lenses 121 and 122.

[0045] There are no particular restrictions on the lines 131 and 132 mentioned above, as long as they are used to block part of the field of vision of the eyeglass lenses 121 and 122. For example, they can be printed on the eyeglass lenses 121 and 122, or have a film or strip attached to them, or a material with specified rigidity can be bonded to the eyeglass lenses or their frames.

[0046] Furthermore, there are no particular restrictions on the shape of the aforementioned lines 131 and 132, but they are preferably straight lines and dark colors with low saturation, preferably black.

[0047] like Figure 3As shown, according to an embodiment of the present invention, the lines 131 and 132 may be at least one formed laterally on the spectacle lenses 121 and 122. They may be formed with at least one predetermined thickness (t). 31 ~t 33 In the case of multiple lines 131 and 132, each line 131a, 131b, and 131c can be separated by a specified interval (g). 31 ~g 32 )form.

[0048] In this case, when lines 131 and 132 are formed laterally, they can correspond to the horizontal direction of the glasses 100. However, according to a preferred embodiment, since the height of each person's eyes or the height of their pupils are different, it is preferable that the lines 131 and 132 be formed laterally to correspond to the tilt formed by the height of the pupils of a person looking straight ahead.

[0049] Furthermore, although there are no particular restrictions on the position (or height) of the lines 131 and 132 formed on the eyeglass lenses 121 and 122, since there is a need for users to see text placed on the ground, it is preferable that they be formed at a position that is slightly tilted downward from the middle height of the eyeglass lenses 121 and 122.

[0050] On the other hand, preferably, the thickness (t) of the transversely formed lines 131, 132 is... 31 ~t 33 The thickness is 1.5mm to 4mm, more preferably 1.5mm to 2mm. When the thickness is greater than 2mm, the area of ​​the floating line does not seem to be significantly different compared to the case with a thickness of 2mm. On the contrary, when the thickness is greater than 3mm, there is a problem of obscuring the target.

[0051] Furthermore, there can be multiple horizontally formed lines 131 and 132, preferably two to four. When using spectacle lenses 121 and 122 with the multiple lines 131a, 131b, and 131c, since the user can clearly see the area between the highest line 131a and the lowest line 131c among the multiple lines 131a, 131b, and 131c in the target, it is preferable that adjacent lines 131 and 132 should be spaced at a predetermined interval (g). 31 ~g 32 Grouping is formed. In this case, the interval (g) between two adjacent lines 131 and 132 is... 31 ~g 32 The thickness is 1.5mm to 3mm, more preferably 1.5mm to 2mm.

[0052] On the other hand, such as Figure 4 As shown, another embodiment of the present invention has the above-mentioned specifications (thickness (t)).41 ~t 43 ), number, interval (g 41 ~g 42 ) and the like) can be formed longitudinally.

[0053] This is because, in general, text is arranged horizontally, but there are many cases of vertical arrangement depending on the country or culture, and thus the above lines 131, 132 can be formed longitudinally.

[0054] In addition, as Figure 5 indicated, at least one line 131, 132 having the above specifications (thickness (t 51 ~t 53 ), number, interval (g 51 ~g 52 ) and the like) can be formed diagonally, and can be formed by selecting two or more combinations from among the horizontal lines 131a, 131b, 131c, the vertical lines 141a, 141b, 141c, and the diagonal lines 151a, 151b, 151c, whereby a plurality of or various patterns of lattices can be formed.

[0055] Experimental Example 1

[0056] Figure 6 To show various experimental examples of the vision correction lens according to an embodiment of the present application, one horizontal straight line having various thicknesses was formed, and 50-year-old and 60-year-old men and women living in Seoul were asked to fix their gaze on a word printed in 7-point size located 30 cm to 40 cm in front of the glasses, and the clarity and readability were evaluated on a 5-point scale. In this case, the higher the clarity and readability, the higher the evaluation score, and the results are shown in Table 1 together with the opinions.

[0057] Table 1

[0058]

[0059] Experimental Example 2

[0060] Unlike Experimental Example 1 above, two horizontal lines having various thicknesses were formed, and experiments were performed on the same subjects, and the results are shown in Table 2 together with the opinions.

[0061] Table 2

[0062]

[0063]

[0064] However, in the case of the above object #6, when the interval between the two lines is 2 mm, it is possible to see clearly because there is no blurred portion in the middle, and thus, preferably, the optimal interval between the lines should be less than 3 mm.

[0065] Experimental Example 3

[0066] Unlike the above Experimental Example 1 or Experimental Example 2, four transverse straight lines of various thicknesses were formed and experiments were performed with the same object, and the results are shown together with the opinions in Table 3.

[0067] Table 3

[0068]

[0069]

[0070] However, in the case of the above object #8, when a large area is viewed at the same time, the readability is relatively high, but when one portion is focused on, for example, in the case of reading a book, the clarity is slightly lower than #6 because of the dispersion of concentration.

[0071] On the other hand, in the above experimental examples, when the target located at 30 cm to 40 cm is fixated according to the reading distance, although the corrective vision effect for presbyopia is provided by improving the clarity, when the target located at a close distance is fixated, the effect of seeing the target will be slightly reduced, and thus, it is more suitable for a close distance than for a long distance.

[0072] The present application has been described in detail with reference to the preferred embodiments. It should be understood, however, that the description is illustrative only and the present application will be readily modified by those skilled in the art without departing from the technical idea or essential characteristics of the present application.

[0073] Therefore, compared to the above detailed description, the scope of the present application should be indicated based on the scope of the invention, and all modified or modified embodiments derived from the meaning, scope and equivalent concepts of the scope of the invention are within the scope of the present application.
