The present invention relates to a spectacle lens for ocular dysfunction, and more particularly to an ophthalmic disorder such as amblyopia or strabismus and to correct or ocular dysfunction spectacle lenses.

Vision is the ability of the eye to recognize the shape or existence of an object. Visual acuity depends on refractive error or ocular disease, and refractive error is expressed by circle / myopia, correction / uncorrected visual acuity according to various classification methods.However, corrective vision is required when wearing glasses or contact lenses is a premise. This has great meaning.

In the corrected visual acuity, amblyopia that is not corrected even by wearing glasses or contact lenses or the like, and strabismus, which may cause visual problems, are problematic. The amblyopia is an ophthalmic examination, in which there is no vision in one or both eyes without any disease in the retina, and it is not corrected with glasses. Strabismus also refers to a symptom of asymmetrical biasing of the black part of the eye. In addition, there are double visions in which people live, and these double visions lead to confusion in a state of confusion. Therefore, strabismus continues and changes to a state of suppression that ignores one eye to avoid confusion. This state of inhibition acts as a barrier even in strabismus surgery, causing a problem of worsening the outcome of the surgery.

In addition, amblyopia and strabismus are not only eye diseases that can lead to blindness, but they can also be fatal to social life by inhibiting appearance.

The conventional method for improving the ophthalmic diseases as described above has been used to normalize using a weak eye or acute eye by covering the normal eye with an eye patch or a shade. However, this may have some effect of restoring weak eyes, but it prevents the use of normal eyes for a long time, and thus has a disadvantage of deteriorating vision in normal eyes in return for restoring weak eyes. In addition, even if amblyopia recovers to some extent, normal eyes and amblyopia do not harmonize with each other, and there is a problem in treatment, such as no way to perform the narrowing of the left and right eyes.

In addition, the eye patch has a problem in that it is difficult to treat the secretions of the eye, it is uncomfortable to wear, it is difficult to maintain the persistence of the therapeutic effect. Surgery was the only method in the case of strabismus, and even if surgery, the reinforcement treatment to improve the prognosis has not been specifically taken. In addition, in the case of intermittent strabismus at the boundary between strabismus and latent strabismus, only the operation was observed.

In order to improve this problem, Korean Patent Invention No. 1131991 proposes a lens in which a concave-convex portion consisting of a concave portion and a convex portion continuously formed over the entire eyeball side of the wearer is formed on the lens body (see FIG. 1).

This conventional method has the same problem as the method of using the eye patch as a method of completely shielding the normal eye to improve the disease, it is only replaced with a lens for eyeglasses in the eye patch, it is only used for cosmetic purposes while shielding function This is possible, but there is a problem that the correction effect is not achieved. In addition, even in cosmetic purposes, as shown in Fig. 1, it is questionable whether one lens is remarkably opaque and the cosmetic purpose can be realized.

Therefore, it was eager to develop a lens for eyeglasses that could meet the cosmetic objectives while increasing the resolution of amblyopia and allowing other trials such as melting and restraining recovery.

An object of the present invention for solving the above problems is for ophthalmic diseases such as amblyopia or strabismus, selectively shielding the part to be shielded using the spectacle lens, to increase the resolution of the problem in order not to see the strabismus, etc. It is to provide an eyeglass lens for correcting the eye function, such as not to produce aesthetic discomfort.

Another object of the present invention is to provide a spectacle training glasses such as a training session, restraining recovery, improvement of the narrow eye movement of the left and right eyes, a fusion.

In the present invention for achieving the above object in the corrected ophthalmic function lens, a portion of the spectacle lens is made of a transparent portion and the other portion is formed of a translucent portion, the transparent portion is translucent toward the translucent portion, the translucent portion toward the transparent portion It provides a spectacle lens for correcting ocular dysfunction that becomes transparent.

Accordingly, the spectacle lens according to the present invention is worn in the normal to correct amblyopia, so that the transparent portion is provided on the upper portion of the spectacle lens, and the translucent portion is provided for correcting the malfunction of the eye function is formed in the lower portion of the spectacle lens.

In addition, the spectacle lens according to the present invention is worn in the normal to correct the strabismus provides a spectacle lens for correcting the malfunction of the eye function is formed in the upper portion of the translucent portion, the transparent portion in the lower portion of the spectacle lens.

In addition, the spectacle lens according to the present invention is worn in the top to correct strabismus, and the translucent portion provides the spectacle lens for correcting ocular dysfunction formed on the inner side of the spectacle lens and the transparent portion on the outer side of the spectacle lens.

In addition, the spectacle lens according to the present invention is worn in the normal for lack of congestion training, so that the translucent portion is provided on the inner lower portion of the spectacle lens, the transparent portion provides an ophthalmic malfunction correcting spectacle lens formed on the outer portion of the spectacle lens.

Furthermore, the present invention is provided with the corrective spectacles attached to the corrective spectacle lens, the corrective spectacle lens is attached to the normal inner side, the corrective spectacle lens is attached so that the transparent lens is attached to the corrected inner side Provide corrective glasses.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, it should be noted that the same components or parts in the drawings represent the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention. In the present specification, the spectacle lens will be described as an example of a spectacle lens.

2 is a view illustrating a spectacle lens according to an exemplary embodiment of the present invention. A portion of the spectacle lens 100 may be formed of a transparent portion 110, and the other portion may be formed of a translucent portion 120. In addition, the transparent portion 110 may be translucent toward the translucent portion 120, and the translucent portion 120 may be formed to become transparent toward the transparent portion 110. The spectacle lens according to the present invention is used in the normal eye, and when the amount of strabismus varies according to the distance change, the spectacle lens may be worn in the normal eye and the translucency of the spectacle lens may be determined differently according to the pattern of the strabismus.

In the spectacle lens, the upper part of the spectacle lens, the central part of the spectacle lens, or the upper part of the central part can be viewed from a long distance, and thus the lower part of the spectacle lens, the inner side (nose side) or the lower part of the spectacle lens is about 16 mm lower. It is a part where you can watch near (about 40cm) as a part. This led to a similar view of both eyes in order to induce fusion.

The transparency of the spectacle lens is set to 100 for complete transparency and 0 for complete opacity.

Hereinafter will be described an example in which the spectacle lens of the present invention can be applied to the case of amblyopia and strabismus.

3A and 3B illustrate an example in which the spectacle lens according to the exemplary embodiment of the present invention is applied to a weak eye correction. Amblyopia is an ophthalmologic examination that shows visual acuity in one or both eyes without any disease in the retina and is not corrected with glasses. The main causes are strabismus, refractive error (myopia, primordial, astigmatism, etc.), and turbidity of the eyes. The types of congenital amblyopia, strabismus, and strabismus, which are seen in strabismus, are not known at all. There are amblyopia due to refractive error and amblyopia seen in immobility.

And amblyopia is the most common cause of amblyopia. When a child has strabismus, he / she sees two objects because of the amblyopia. In addition, if there is a significant difference in the refractive indices (myopia, primordial, astigmatism) of both eyes, it is not seen by the bad eye, and amblyopia occurs in the eye. In this case, there is no difference between the two eyes. In addition, when there is turbidity in the structure of the eye, such as cataracts, both eyes are not evenly stimulated, resulting in amblyopia.

The principle of treatment of amblyopia is to increase vision by at least 9 years old when eyesight is corrected. A common practice is to cover good eyes for weeks or months, sometimes using eye drops that widen the pupil, or use convex lenses to reduce good eyesight, causing bad eyes.

In particular, the refractive amblyopia is likely to occur when there is a hyperopia, and the following describes the spectacle lens according to the present invention as an example of the refractive amblyopia.

As shown in FIG. 3A, the amblyopia spectacle lens according to the present invention is worn in the top, so that the transparent part 110 is located at the upper part 210 of the spectacle lens, and the translucent part 120 is located at the lower part 220 of the spectacle lens. It may be provided to be formed. Accordingly, the upper 210 and lower 220 should be gradually made transparent and translucent. For example, the transparency of the transparent portion 110 may be 100 to 50, the transparency of the translucent portion 120 may be formed to 50 to 0, in particular, the transparency of the transparent portion 110 is 100, the transparency of the semi-transparent portion 120 Is preferably formed to 20. In this case, the transparency can of course be changed depending on the degree of abnormality, correction degree, abnormal compounding degree, etc. of the box.

Therefore, the spectacle-applied spectacle lens is applied to the spectacle eyeglasses according to the present invention in the normal eye, the normal eyeglasses are worn in the amblyopia to induce the amblyopia to see both clear and long distance, the normal eye is clear or slightly By blurring and inducing the near vision to minimize the inconvenience in life, while continuing to apply a minute visual stimulation of the near can improve the resolution of the weak eye. In addition, by controlling the transparency of the normal eye can always make the binocular function of both eyes. It can also improve the resolution of persistent near vision.

4A and 4B illustrate examples of spectacle lenses that may be applied to an exotropia, in particular, intermittent exotropia. Strabismus refers to a symptom of asymmetrical bias of the black region of the eye, and here, esotropia toward the nose. And exotropia biased toward the ear. Esotropia usually occurs before and after 3 years of age, while exotropia is the most common at the age of 7, later latent, and later biased. Strabismus is caused by an imbalance in the muscles that move the pupil, an imbalance in the dominant nerve, and a trauma. The cause of the strabismus is unknown. In addition, strabismus can occur in cases of trauma, Down syndrome, vision loss in one eye, and cataracts. In general, adjustable esotropia due to hyperopia during strabismus often improves only with primitive orthodontic glasses. At this time, wearing glasses is used as a treatment rather than surgery, and a shielding method is used to prevent amblyopia due to strabismus. This is a treatment that does not cover part of the eyes with good eyesight and uses the eyes on the strabismus.

In particular, exotropia refers to strabismus with the black pupil of one eye turning outwards, and in most cases intermittent exotropia progresses to such an exotropia. Like this, sometimes a strabismus with one eye turning outwards intermittently. Patients with intermittent exotropia are a characteristic symptom when they go out in the sun and grimacing or rubbing one eye.

As shown in FIG. 4A, the ophthalmic spectacle lens according to the present invention is worn in the top, so that the translucent portion 120 is formed at the upper portion 210 of the spectacle lens, and the transparent portion 110 is formed at the lower portion 220 of the spectacle lens. Can be. The upper 210 and lower 220 should be made transparent and translucent gradually. The transparency of the transparent portion is 100 to 50 and the transparency of the translucent portion may be formed to 50 to 0, in particular, the transparency of the transparent portion is preferably 100, the transparency of the translucent portion is preferably formed to 20.

Therefore, the spectacle wearing glasses for the exotropia is worn in the eyeglasses according to the present invention in the normal eye and the normal transparent lens is worn in the exotropia to induce the visual acuity so that both the distance and the near distance can be clearly seen, and the normal eye is only sharp or slightly blurred. The long distance can be blurred to hinder the suppression of astigmatism at long distances, leading to a desirable fusion (the action of bringing together the extraterrestrial objects visible to both eyes).

5 shows an example of application of the spectacle lens according to the present invention in esotropia, wherein the translucent portion 120 is formed on the inner side 240 of the spectacle lens and the transparent portion 110 is formed on the outer side 250 of the spectacle lens. Can be. The inner 240 and the outer 250 should be gradually transparent and translucent. For example, the transparency of the transparent portion is 100 to 50, the transparency of the translucency is formed to 50 ~ 0, the transparency of the transparent portion is preferably 70, the transparency of the semi-transparent portion is preferably formed to 30. In particular, this transparency can be used for distance suppression by strabismus (which occurs when strabismus has progressed for a long time due to disregarding one phase when two objects are seen).

Therefore, the spectacle wearing glasses with esotropia is worn with the spectacle lens according to the present invention in the normal eye, and the transparent eyeglasses are worn in the inner eye cyan to induce visual acuity so that both the long distance and the short distance can be clearly seen. Induced to be blurred when viewed and slightly blurred when viewed from the outside, the far is induced to appear blurred, to prevent the suppression of the cyanide at a distance to induce a desirable fusion.

6 is an example of application of the spectacle lens according to the present invention for lack of congestion (lack of eyeball movement) training, the translucent portion 120 is in the inner lower portion 241 of the spectacle lens, the transparent portion 110 May be formed on the outer upper portion 251 of the spectacle lens. The inner lower part 241 and the outer upper part 251 should be gradually made transparent and translucent.

Convergence refers to the function that when a person with binocular vision sees a point in outer space with both eyes, the line of sight of both eyes gathers at that point. The phenomenon refers to a phenomenon in which the function of collecting the gaze lines of both eyes decreases. If the eye does not turn inward when the subject is close, it can be improved by eye training by push-up. In this case, training with the spectacle lens in non-compliance may be more effective.

Therefore, the corrective spectacles were provided by applying the corrective spectacle lens 100 according to the present invention. The present invention was performed as described below using the corrective glasses provided as described above to see the effect. As a result, superior calibration results are shown for each strabismus and amblyopia, indicating the superiority of the present invention. In addition, since the ratio of the translucent portion and the transparent portion of the corrective spectacle lens 100 is selected and applied according to the state of the translucent portion and the translucent portion of the translucent portion, there is no aesthetic discomfort and there is no inconvenience in social life. .
