[0034] FIG. 2 is a view showing an exterior of eyeglasses including lenses for vision correction according to an embodiment of the present disclosure.

[0035] As shown in FIG. 2, eyeglasses 100 according to an embodiment of the present disclosure may include a pair of eyeglass lenses 121 and 122 and temples 111 and 112 coupled to the eyeglass lenses 121 and 122 to be daped over the user’s ears. The temples 111 and 112 may be hinge-coupled to the eyeglass lenses 121 and 122 such that the temples 111 and 112 may be folded onto the eyeglass lenses 121 and 122.

[0036] According to an embodiment, the eyeglass lenses 121 and 122 may be mounted in a frame. In this case, the temples 111 and 112 may be hinge-coupled to the frame.

[0037] In addition, the eyeglass lenses 121 and 122 or the frame may be provided with a nose support so as to be seated on the user’s nose.

[0038] In contrast with conventional pinhole lenses, the eyeglass lenses 121 and 122 according to the embodiment of the present disclosure may be formed of a a transparent material allowing light to be transmitted therethrough, thereby minimizing the blocking area of the user’s field of view and relieving the frustration caused by the conventional pinhole eyeglasses.

[0039] In addition, as the eyeglass lenses 121 and 122 according to the embodiment of the present disclosure are formed of a transparent material, they may secure a wide field of view. Accordingly, the glasses may be used even in a dark environment.

[0040] At least one line 131 and 132 having a predetermined thickness may be provided on the eyeglass lenses 121 and 122 formed of a transparent material. Stripe 131 and 132 are provided on the eyeglass lenses 121 and 122 to block part of the user’s view of a subject seen through the eyeglass lenses 121 and 122. When the user sees the subject through the eyeglass lenses 121 and 122, a hologram effect may be induced such that the lines 131 and 132 are placed in a space other than a plane.

[0041] That is, as shown in FIGS. 7A and 7B, when the user sees the subject through the eyeglass lenses 121 and 122 according to the embodiment of the present disclosure, the lines 131 and 132 on the eyeglass lenses 121 and 122 may appear floating in the space like a hologram, but the area around the eyeglass lenses 121 and 122 may be seen blurred. In addition, on the subject to be focused through the eyeglass lenses 121 and 122, the areas around the positions of the lines 131 and 132 are clearly seen.

[0042] The lines 131 and 132 are not particularly limited as long as they are intended to block a part of the field of view of the eyeglasses 121 and 122. For example, a detachable film or tape may be used, or a member with a predetermined rigidity may be coupled to the eyeglasses or the frame.

[0043] In addition, the lines 131 and 132 are not particularly limited in shape, and may have a straight line shape, and the color thereof may be dark with low chroma, preferably black.

[0044] According to an embodiment of the present disclosure, at least one of the lines 131 and 132 may be formed horizontally on the eyeglass lenses 121 and 122. At least one line 131, 132 with a predetermined thickness t.sub.31 to t.sub.33 may be provided. When a plurality of lines 131a to 131c is provided, the lines may be arranged spaced apart from each other by a predetermined distance g.sub.31 to g.sub.32.

[0045] In this case, when the lines 131 and 132 are formed horizontally, the arrangement thereof may correspond to the horizontal direction of the eyeglasses 100. According to a preferred embodiment, the lines 131 and 132 may be formed horizontally to correspond to a slope formed by the height of the two pupils of the user facing forward.

[0046] In addition, the positions (or heights) of the lines 131 and 132 provided on the eyeglass lenses 121 and 122 are not particularly limited. Since the user usually requires a clear view of the letters on the floor, the lines may be positioned slightly downward from the middle height of the eyeglasses 121 and 122.

[0047] The lines 131 and 132 formed horizontally preferably have a width (t.sub.31 to t.sub.33) of 1.5 mm to 4 mm, more preferably 1.5 mm to 2 mm. When the width exceeds 2 mm, there is no significant difference from the case where the width of a part of the line that appears to be floating is 2 mm. Further, when the thickness is greater than or 3 mm, the lines may block the view of the subject.

[0048] The horizontal lines 131 and 132 may be plural, preferably 2 to 4. When the eyeglass lenses 121 and 122 having the plurality of lines 131a to 131c are used, the user may clearly see the area of the subject between the top line 131a and the bottom strip 131c among the lines 131a to 131c. Accordingly, the two lines 131 and 132 are preferably grouped and spaced apart from each other by a predetermined distance g.sub.31 to g.sub.32. Here, the distance g.sub.31 to g.sub.32 between the two neighboring lines 131 and 132 is preferably 1.5 mm to 3 mm, more preferably 1.5 mm to 2 mm.

[0049] According to another embodiment of the present disclosure, as shown in FIG. 4, at least one line 131 and 132 having the above-described specifications (width (t.sub.41 to t.sub.43), number, distance (g.sub.41 to g.sub.42), etc.) may be vertically formed.

[0050] The lines 131 and 132 may be formed vertically because text, which is generally arranged horizontally, can be arranged vertically depending on the country or culture in many cases.

[0051] In addition, as illustrated in FIG. 5, according to various shapes of the subject, at least one line 131, 132 with the above-described specifications (width (t.sub.51 to t.sub.53), number, and (g.sub.51 to g.sub.52) may be diagonal. Two or more lines selected from among the horizontal lines 131a to 131c, vertical lines 141a to 141c, and diagonal lines 151a to 151c may be combined to form various patterns.

Experimental Example 1

[0052] FIG. 6 shows various experimental examples of lenses for vision correction according to an embodiment of the present disclosure. In the experiment, a horizontal line of various widths was provided, and 7-point printed letters located 30 cm to 40 cm in front of the eyeglasses were shown to men and women in their 50s and 60s in Seoul, and a five-point scale method was used for sharpness and readability. The higher the sharpness and the higher the readability, the higher the score was evaluated. The results are shown in Table 1 below with the opinions.

TABLE-US-00001 Obje ct Specification Experimental Opinion Score Total Score #1 No. of lines: 1 Width: 1 mm Focusing is not good. The width of the line is thin as 1 mm, and the black hologram effect line is blurred, so the eye reduction effect is weak. Sharpness: 1 Readability: 0 1 #2 No. of lines: 1 Width: 2 mm About 30 mm vertical section above and below the line. the focus is clear. The line does not cover letters, so text above and below the line can be read at the same time. Sharpness: 4 Readability: 3 7 #3 No. of lines: 1 Width: 3 mm About 15 mm vertical section above and below the line. The focus is clear. The line covers letters, so text can only be read in one direction at the top and bottom of the line. Sharpness: 3 Readability: 2 5 #4 No. of lines: 1 Width: 5 mm About 15 mm vertical section above and below the line. The focus is clear. The line covers letters, so text can only be read in one direction at the top and bottom. The black line completely covers the letters. Sharpness: 3 Readability: 1 4

Experimental Example 2

[0053] Unlike Experimental Example 1, two horizontal lines of various widths were prepared, and the experimental results for the same object are shown in Table 2 below with the opinions.

TABLE-US-00002 Obje ct Specification Experimental Opinion Score Total Score #5 No. of lines: 2 Width: 2 mm Distance: 2 mm About 40 mm section between the two lines. Sharp focus. The text in the space between the lines is clearly visible. The clear range is wider and the text is easier to read than when only one line is provided. Sharpness: 4 Readability: 4 8 #6 No. of lines: 2 Width: 3 mm Distance: 3 mm About 50 mm section between the two lines. Partially clear. The text in the space between the lines is clearly visible. The clear range is wider than when only one line is provided. However, the middle part of the range is blurry. The black lines partially cover the text. Sharpness: 3 Readability: 2 5

[0054] For object #6, when the distance between the two lines is 2 mm, there is no blurry part in the middle, the optimal distance between the lines is preferably less than 3 mm.

Experimental Example 3

[0055] Unlike Experimental Example 1 or 2, four horizontal lines of various widths were provided, and the experimental results for the same object are shown in Table 3 below with the opinions.

TABLE-US-00003 Targe t Specification Experimental Opinion Score Total Score #7 No. of lines: 4 Width: 1 mm Distance: 2 mm Poor focus. Due to the thin line of 1 mm width, the black line hologram area is not formed, and the sharpness improvement effect is insignificant. Sharpness: 1 Readability: 0 1 #8 No. of lines: 4 Width: 2 mm Distance: 2 mm The area where the text is clear appears to be the widest. Focusing is somewhat more inconvenient than when one or two lines are provided Sharpness: 3 Readability: 5 8

[0056] In the case of object #8, the readability is high when a large area is seen at the same time. However, when the user concentrates on one part as in reading, the concentration is distracted compared to the case when two lines are provided, and the sharpness is slightly lower than in the case of object #6.

[0057] in the above experimental examples, when a subject located at a reading distance of 30 cm to 40 cm was seen, the sharpness was increased and the effect of vision correction for presbyopia were obtained. However, when a subject located at a long distance was seen, the clarity of the view of the subject was somewhat low. Thus, the eyeglasses may be suitable for short distance.

[0058] While present disclosure has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made herein without departing from the spirit and scope of the present disclosure as defined by the appended claims.

[0059] Accordingly, the scope of the present disclosure is to be defined by the claims below rather than the detailed description, and all changes or modifications derived from the meaning, scope, and equivalent concept of the claims are included in the scope of the present disclosure.
