Description

[0001] The present invention relates to a lens for enhancing amblyopia, diplopia and concentration,

The present invention relates to a lens specially designed for the treatment of amblyopia and diplopia, and to a specially designed lens for enhancing concentration, and to a spectacle using the lens. More particularly, the present invention relates to a lens used for treating amblyopia or diplopia, The present invention relates to a lens for use in amblyopia, diplopia, and intensifying power for enhancing user's satisfaction while enhancing a therapeutic effect by compensating for defects in which a wearer is prevented from wearing due to defects of a wearer, and glasses using the same.

Amblyopia can not detect any abnormality due to ophthalmologic examination. If there is a difference between the two eyes of both eyes in the visual acuity chart that the corrected visual acuity (visual acuity corrected with glasses or contact lenses) The lower vision is called amblyopia. In most cases, strabismus is accompanied. The causes of amblyopia include strabismic amblyopia, obtuse amblyopia, amblyopic amblyopia, amblyopia, and ambiguous amblyopia. Strabismic amblyopia suppresses macular function in eyes with strabismus to avoid diplopia (overlapping objects) caused by strabismus. . As a result, both sides of the eye see different directions. In this case, the images received in the right eye and the left eye are different from each other, causing confusion and suppressing the image from one side to prevent confusion. When this phenomenon lasts for a long time, the suppressed eye continues to develop weak vision. And amblyopic amblyopia is an amblyopia caused by not using eyes. If you do not use your eyes for a long period of time, its function will deteriorate as muscles lose their strength if they are not used for a long time. If you hide one eye during the period of sight development, your eyesight will not come out after a long period of time even if there is no special abnormality in your eyes. Refraction abnormal amblyopia is caused by myopia, primordia and astigmatism, but it is caused by uncorrected amblyopia. I am accustomed to this blurred image when I see the unclear blurred image because the refraction abnormality is not corrected. Refractive anisometropia is an amblyopia caused by differences in the degree of refraction of both eyes. When one eye is well visible and one eye is difficult to see due to severe irritation or nearsightedness, only eyes that are well visible are used. . Finally, temper ambiguity is an amblyopia caused by a visual pathway disorder that can not be examined by the eye.

If you have a disease that causes strabismus or other amblyopia, treat the underlying disease. In the case of amblyopia due to refraction abnormalities, correct refractive error, induce the good eye to continue to use the cyanide, and continue until both eyesight is the same. It is difficult to continue occlusion therapy if the visual acuity of the cyanide is not improved or the compliance is significantly poor due to good occlusion therapy. Substance amblyopia is untreated, and it is recommended that low vision aids be supported by low vision aids. In general, if one eye is good and the other eye has poor eyesight, not only the child but also the caregivers often do not know it. Therefore, even if the child seems to have no abnormality, he or she should go to the ophthalmology department and have a general examination about the eye when it is about 3 years old.

This early detection and treatment of the prognosis is good, too late to find the treatment is not. The period of development of visual acuity is from birth to about 8 years old. Treatment of amblyopia also has treatment period, and it can be cured normally by early treatment, and its ratio is about 2 ~ 5% of the whole population do.

The diplopia is a monocular diplopia (diplopia) and a binocular diplopia (diplopia). Monocular diplomas are such that there is a shadow on an object and it is often seen in astigmatism. In addition, binocular diplopia occurs when the visual action of the visual cortex in the cerebral occipital lobe (the action of aligning the outer object image of the two eyes) or eye movement abnormality, especially ophthalmoplegia. The eyeballs are moved by the six oculomes of each eye, and when any of the eyes of the eyeballs are paralyzed, the eyes of both eyes are not directed to the same target. And the image of the paralytic eye appears at the position of the upper, lower, left, and right sides of the healthy eye, and the object appears in two. This state is referred to as "repetition" in which the head is fixed, and only the eyes are moved and the description is made in eight directions. In unilateral cases, lens dislocations, early cataracts, corneal damage or astigmatism, and bilateral cases are often caused by ocular paralysis. In addition, stable fatigue, hysteresis, and sometimes without going through the physical abnormalities, most of them recover within six months after the onset.

In the case of amblyopia, the vision can be improved by appropriate treatment at the age of 9 to 10 years. In the past, eyes with good eyes (or normal eyes) were hidden by the eyes, And in the case of diplopia, it was a common treatment method to wear an eye patch to restore diplopia.

However, there are some problems in the method of treating by wearing the above-described eye. First, there is the inconvenience that the eye should be replaced at regular intervals by the dispenser attached to the inner side of the eye, which is secreted from the eye. Especially, in the case of strabismus due to trauma, diplopia often remains after the operation. In addition, wear of the eye is apparently aesthetic defects, especially in children and adolescents, because the eye is frequently removed, the treatment is less effective and the treatment effect is lowered. The tape used as an adhesive when wearing the liner causes problems such as dermatitis, rash, and itching in the face.

Prior art relating to lenses for treating amblyopia and diplopia is disclosed in Korean Patent Laid-Open Publication No. 10-2008-0097737 in which a part of a spectacle lens is made of a transparent part and the other part is formed of a translucent part, And the translucent portion becomes transparent as the transparent portion becomes transparent. Korean Patent Laid-Open Publication No. 10-2011-0099409 discloses an eyeglass lens for eye surgery, And a blindfold for attaching to the inner side of the lens, which is capable of providing help to an adult who desires occlusion therapy by cataract surgery or the like.

In order to solve the above problems, the present invention aims to solve the problem that the eye is changed at regular intervals during the treatment period, In this case, the wearer's eyes are clearly visible so that no apparent aesthetic defects appear, and when viewed from the inside of the eyeglasses, an external object is not visible, thereby providing an effect of concealing normal eyes instead of the conventional eye, The present invention aims to provide a lens for use in amblyopia, diplopia, and concentration-enhancing treatment which is constructed so as to be able to be used even if such a defect occurs, and a spectacle using the same.

A convexo-concave portion 32 and a convexo-concave convex portion 31 which are continuously formed over the entire surface of the outer surface of the lens body 1, which is the opposite side of the eyeball side of the wearer in the lens body 1, And the radius of curvature of the concavo-convex concave portion 32 and the concavo-convex block portion 31 is R> R. The convex concave portion 32 has a radius of curvature R, the concave- convex convex portion 31 has a radius of curvature r, > r. Preferably, the radius of curvature of the convex-concave convex portion 31 is '0'. The radius of curvature of the concavo-convex concave portion 32 of the concavo-convex 21 can be controlled by the concavo-convex coating layer 25 of the curable liquid optical material, and preferably the outer surface of the lens body 1 is coated with the anti- ).

In the lens body 1, the ordinary coating layer 12 exists like the conventional coating layer on the eyeball side of the wearer, the concave and convex portions 21 are formed on the outer side of the lens body 1, which is the opposite side of the eyeball side, , A concavo-convex coating layer (25) is formed on the concave portion in the concave and convex portion (21), and an antireflection multi-coating layer (11) is formed on the outside front side.

According to the present invention, it is possible to individually treat the problems such as weakness and diplopia by using lenses for strengthening amblyopia, diplopia, and concentration, and glasses using the lenses. By using the selective shielding method, In the case of children, it is difficult to manage eyeglass lenses as compared with adults, but normal treatments can be performed even for small scratches or scratches. Therefore, The satisfaction of the wearer is increased, and the therapeutic effect can be enhanced.

In the following description of the present invention, In the case where it is judged that the gist of the invention may be blurred unnecessarily, detailed description thereof is omitted. The following terms are defined in consideration of functions in the present invention, and may vary depending on the intention of the user, the intention of the operator, or the customs. Therefore, the definition should be based on the contents throughout this specification.

FIG. 1 is a plan view of a lens for amblyopia, diplopia and concentration-enhancing treatment and glasses using the same according to the present invention. FIG. 2 is an enlarged view of a lens for amblyopia, diplopia, Referring to FIG. 2,

When the lower surface of the lens body 1 is set to the eyeball side of the wearer and the upper surface of the lens body 1 is set to the lens outer side, fine irregularities 21 are uniformly formed on the outer surface of the lens body 1 of the present invention .

The general coating layer 12 is present in the order from the eyeball side to the outside side of the lens body 1, and irregularities 21 are present on the general coating layer 12. The concave and convex portions 21 constitute a concave and convex convex portion 31 and a concave and convex concave portion 32 and the concave and convex concave portion 32 constitute a concave and convex coating layer 25. An antireflective multi-coating layer 11 is formed on the concave and convex portions 21 to form the lens main body 1.

The concave and convex portions 21 are formed by the convex and concave convex portions 31 and the convex and concave concave portions 32 continuously formed over the entire outer surface of the lens body 1, The irregular concave portion 32 has a radius of curvature R and the convex-concave convex portion 31 has a radius of curvature r. At this time, the radius of curvature of the concavo-convex concave portion 32 and the concavo-convex convex portion 31 has a relation of R >> r. In a preferred embodiment, the radius of curvature r of the convex-concave convex portion 31 is '0'.

In order to form such irregularities on the entire surface of the lens body 1, it is important to precisely control the curvature radii R and r of the irregular convex portions 31 and the irregular concave portions 32. [ Generally, in order to form the unevenness 21 as described above, the surface of a casting mold for manufacturing a lens using glass or plastic is processed by precision machining, grinding, etching method using chemical substances, It is possible to process the lens body 1 having the lens 21 formed thereon.

However, by controlling the curvature radius of the protrusive convex portion 31 and the protrusive concave portion 32 of the protrusions 21 by forming the protrusions 21 on the front surface of the lens body 1 by this method, Processing method and the like are very complicated. Therefore, by using a mold having sharp and rough irregularities formed on the surface by a method such as ordinary grinding, sanding or etching, the irregular convex portion 31 and the irregular concave portion 32 formed on one side of the lens body 1 (21) is formed, and the irregular coating layer (25) is formed by dipping or spinning a curable, optically transparent liquid material. At this time, the curvature radius of the concave / convex concave portion 32 can be easily and appropriately controlled by the surface tension of the liquid material by appropriately controlling the coating amount.

The outer surface of the lens body 1 is preferably formed of zirconium oxide or silicon oxide to form an anti-reflective multi-coating layer 11.

As described above, light scattering occurs on the surface on which the concavities and convexities 21 are formed, so that the image is blurred, and an external object is not visible from the eyeball, but the eyeball is visible from the outside. This is because in the case of the wearer wearing the lens body 1 of the present invention, since the image of the eyeball is located at a short distance from the concave and convexes 21, the light emitted from the eyeball of the wearer passes through the irregularities 21 of the lens body 1 The light is incident almost perpendicularly to the tangential surface of the curved surface of the concavo-convex concave portion 32 of the concave and convex portions 21 within a certain angle range. In other words, since the incidence angle is as small as '0' and the refraction is small, it is almost straight. Therefore, when an external person at a distance from the concavity and convexity 21 sees the wearer's eyeball, the image of the eyeball is normally seen without being refracted, and the image of the external object is located far away from the concave and convexes 21, Since the incoming light passes through the concave and convex portions 21 of the lens body 1 at a plurality of incident angles, irregular refraction occurs and light is scattered, so that the image of the external object is not clearly distinguished and is almost invisible.

As described above, the wearer can hardly see the external object, while the eyes of the wearer wearing the lens body 1, which is the present invention, can be clearly seen from the outside.

The antireflection multi-coating layer 11 can be formed on the outer side of the lens body 1. If the refractive index n 'of the lens body 1 is 1.5, then the reflectance at the outer surface of the lens body 1 and the reflectance at the inner surface of the lens body 1 are expressed by the following equations It is '4%' by the expression.

Therefore, when the eyeball of the wearer is seen from the outside of the lens body 1, it appears to be somewhat opaque due to the reflection according to the reflectance and the scattering by the irregularities 21 formed inside the lens body 1. At this time, when the anti-reflective multi-coating layer 11 is formed, the reflectance at the outer surface and the reflectance at the inner surface are made to be '0' and scattering is prevented, so that the eyeball of the wearer can be seen more clearly from the outside .

FIG. 3 is a view showing an example of a lens for amblyopia, diplopia and concentration-enhancing treatment and glasses using the same according to the present invention, and will be described in detail with reference to FIG.

As shown in Figs. 3 (a), 3 (b) and 3 (c), the lens body 1 of the present invention is disposed in a peripheral portion excluding the central portion of the lens, A lens b disposed at the lower end of the lens, and a lens c disposed at the upper end of the lens. The lens body 1, which is an object of the present invention, , It is possible to perform treatment appropriate to each situation by using characteristics that are not well visible.

(a), the wearer can see the outside only through the general lens 50 located at the center of the lens, and can not see through the lens body 1 formed at the periphery of the lens. (b) and (c), the wearer can see the outside only through the general lens 50 located at the upper or lower end, and can not see through the lens body 1 formed at the lower end or the upper end.

By using such a principle, it is possible to treat amblyopia and diplopia in accordance with each situation, and it is also possible to perform concentration-strengthening treatment by adjusting to be able to gaze at one place by forcibly, So that the treatment function of the lens body 1 is not deteriorated even with general scratches or scratches, so that it can be easily managed.

In the present invention, the above embodiments are merely examples, and the present invention is not limited thereto. Anything that has substantially the same structure as the technical idea described in the claims of the present invention and achieves the same operational effect is included in the technical scope of the present invention.
