Description

Vision Correction Filter and Vision Correction Method Using the Same

The present invention relates to a vision correction filter for removing an eye strain to enable accurate vision correction, and a vision correction method using the same.

In general, a method of measuring visual acuity uses subjective visual acuity using an eye chart or an optometry. Here, in the ophthalmology measurement using an optometry, the eye of the examinee is irradiated with the measurement light, photographs the light reflected by the cornea of the subject, and analyzes the photographed image to measure vision or measure the state of the eye. The optometrist includes an optical source for measuring vision, an optical system forming a path of light, and a camera for capturing an image of light through the optical system.

In this way, the lens is prescribed to adjust the visual acuity of the subject's left and right eyes to 1.0 based on the visual acuity measured by the subjective optometry or the optometry.

However, when measuring vision by subjective optometry or optometry, by prescribing the lens to 1.0, which is the reference visual acuity while the subject's eyes are in tension, the eye is kept in tension even when the lens is worn in the corrected state. There is a problem that the eye fatigue increases when worn for a certain time.

Such a conventional eye measurement method is presented in Korean Patent Laid-Open Publication No. 2004-0023945 (2004.03.20).

The present invention provides a vision correction filter and a vision correction method using the same to prevent eye fatigue from increasing even when worn for a long time even in the state corrected by the corrective lens by measuring the vision in a state in which the tension state of the subject's eye is relaxed. The purpose is to.

According to an aspect of the present invention, a pair of lens insertion holes are formed through the lens frame spaced apart from each other, a pair of plus (+) lenses respectively installed in the lens insertion hole of the lens frame, the plus (+) The lens provides a vision correction filter that reduces the tension of the eye of the subject by decreasing it to 0.15 to 0.35 based on each monocular correction vision 1.0 of the subject.

In addition, according to another aspect of the invention, the step of preparing the vision correction filter of claim 1, after checking the eyesight of the subject, wearing a corrective lens to adjust each monocular vision of the subject to 1.0, the corrective lens Arranging the vision correction filter in front of the, lowering the monocular visual acuity of the subject to 0.15 to 0.35, respectively; And replacing the corrective lens so that the vision table is clearly visible, and removing the corrective filter disposed in front of the corrective lens.

In the vision correction filter and the vision correction method using the same according to the present invention, each of the monocular vision is first corrected to 1.0 by the corrective lens lowering the positive (+) lens of the vision correction filter to 0.15 ~ 0.35, After the eye is relaxed, vision correction through re-examination of the subject is performed, thereby preventing eye fatigue even if the lens is worn for a long time.

Figure 2 is a flow chart showing a vision correction method using a vision correction filter according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic cross-sectional view of a vision correction filter according to an embodiment of the present invention. Referring to FIG. 1, the vision correction filter 100a includes a lens frame 100 and a plus (+) lens 200.

The lens frame 100 is a part for supporting the plus (+) lens 200 to be described later in a detachable state. Here, the pair of lens insertion holes 110 are formed in the lens frame 100 to be spaced apart from each other by a predetermined interval. The lens insertion hole 110 is inserted into the plus (+) lens 200. In FIG. 1, the lens frame 100 is illustrated as having a flat plate structure. However, the lens frame 100 is not limited thereto, and an earring portion (not shown) may be additionally connected to be disposed on the ear of the examinee. Of course.

In addition, a pair of sliding grooves 120 may be formed in the lens frame 100 to communicate with the lens insertion hole 110, respectively. The sliding groove 120 is provided with an opaque shielding plate 130 to be slidable to selectively cover the plus (+) lens 200 inserted into the lens insertion hole 110. . That is, the obstruction plate 130 allows one side to be screened when the eyesight measurement of the subject's monocular, that is, the selective eyesight measurement for the left or right eye.

The plus (+) lens 200 is a tension state of the eye of the subject while lowering the vision from 0.15 to 0.35 based on each monocular vision 1.0 in the state in which the subject is wearing a corrective lens when measuring the vision of the subject It is a lens to alleviate. The positive (+) lens 200 may be (+) 0.60D to (+) 0.85D. In this case, when the positive (200) lens is less than (+) 0.60D, the tension state of the examinee's fistula may not be stabilized, and when the positive (+) lens is higher than 0.85D, the examinee There is a problem that it is difficult to measure the vision table through the plus (+) lens 200 can not see the vision table.

Figure 2 is a flow chart showing a vision correction method using a vision correction filter according to an embodiment of the present invention. Referring to FIG. 2, first, the optical correction filter 100a described above is prepared.

When the sight correction filter 100a is prepared, the corrective lens is worn after the vision of the subject is examined. That is, after the eyesight of the subject is examined using an optometrist or an eye table, the corrective lens is worn so that each monocular vision of the subject becomes 1.0.

In this way, after the corrective lens is worn such that each monocular vision of the subject becomes 1.0, the vision correcting filter 100a is disposed in front of the corrective lens worn by the subject.

As such, when the vision correction filter 100a is disposed in front of the corrective lens of the subject, the monocular vision of the subject becomes low. That is, the left eye and the right eye can be lowered to 0.15 to 0.35 through the corrective lens to relieve eye strain. At this time, in order to lower the left eye and right eye through the corrective lens of the subject to 0.15 ~ 0.35, respectively, the positive (+) lens 200 of the vision correction filter (100a) is (+) 0.60 ~ (+ ) Has a frequency of 0.85D.

As such, after reducing the monocular vision through the corrective lens and the vision correction filter 100a of the subject to 0.15 to 0.35, the subject shows the vision table of 0.15 to 0.35. In this case, if the examinee clearly sees the 0.15 to 0.35 visual acuity table, it is no longer necessary to replace the left and right lenses of the corrective lens.

However, when the subject does not see the 0.15 ~ 0.35 vision table clearly, the subject replaces the power of the lens disposed on the left or right side of the corrective lens that can see the 0.15 ~ 0.35 vision table clearly. In this case, the corrective lens is a positive (+) lens, and the power of the lens to be replaced may be selectively used to clearly see the visual acuity table of 0.15 to 0.35.

In this way, after replacing the correcting lens so as to clearly see 0.15 to 0.35 eyesight table with monocular while wearing the corrective lens of the subject and the corrective filter 100a, the front of the corrective lens By removing the disposed sight correction filter 100a, the vision correction of the subject is completed.

As described above, the vision correction filter and the vision correction method using the same according to the embodiment of the present invention include a positive (+) value of the vision correction filter (100a) of the reference vision, the initial correction of each monocular vision through the corrective lens to 1.0. Since the lens 200 is lowered to 0.15 to 0.35, the eyesight of the subject is corrected in a state in which the eye strain of the subject is alleviated, the eye fatigue can be prevented even if the lens is worn for a long time.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
