Description
本発明はプリズムを使用することで、見る対象物に向かう方向よりも強い輻輳（内寄せ）を視線に生じさせ、もって近視治療を行う近視治療具である。 The present invention provides a myopia treatment tool that uses a prism to cause a convergence (inward alignment) in the line of sight stronger than the direction toward the object to be viewed, thereby performing myopia treatment.
眼球の基本構造は図１のようであり、対象物からの反射光は眼球前部の水晶体を通る際に屈折し網膜上に明瞭な像を結ぶ。近くの対象物を見る時は水晶体を厚くし、遠くの対象物を見る時は水晶体を薄くする。近視眼とは、対象物の距離に対して必要以上に水晶体を厚く調節してしまい網膜上に明瞭な像を結べなくなった状態である。
従来の近視治療具は対象物を遠ざけたり近づけたりを繰り返す、あるいは眼前にレンズを設置し、そのレンズの強度を変化させるなどして水晶体の厚さを変化させる眼球の機構の訓練あるいは柔軟性の回復を目指すものであった。
両眼の輻輳（内寄せ）と水晶体の厚さを調節する機構は自動的に連動するようになっており、これを輻輳反射という。近視の原因を、水晶体を厚くする毛様体筋や両眼を輻輳（内寄せ）させる内転筋の過度の緊張に求め、その緊張を解くために両眼の輻輳を弱めようとした近視治療具が先行技術文献の特許文献１である。この特許文献１の近視治療具も本発明と同様に図４のごとく両眼の前にプリズムを設置するが、その向きは内側（鼻側）にプリズムの厚い方を、外側（耳側）にプリズムの薄い方が来るようにしている。このようにすると、対象物からの反射光は内側に曲げられ、その結果、視線が外側に開き輻輳（内寄せ）の度合いを弱める。これは本発明とはまったく逆である。The basic structure of the eyeball is as shown in FIG. 1, and the reflected light from the object is refracted when passing through the lens in the front of the eyeball and forms a clear image on the retina. When looking at a nearby object, the lens is thickened, and when looking at a distant object, the lens is thinned. The myopic eye is a state in which the lens has been adjusted to be thicker than necessary with respect to the distance of the object, and a clear image cannot be formed on the retina.
Conventional myopia treatment tools repeatedly move the object away and close, or install a lens in front of the eye and change the lens strength to change the lens thickness, etc. It was aimed at recovery.
The mechanism that adjusts the convergence (inner alignment) of both eyes and the thickness of the lens is automatically linked, and this is called convergence reflection. Myopia treatment that seeks the cause of myopia in the ciliary muscle that thickens the lens and the excessive tension of the adductor muscle that converges both eyes and tries to weaken the convergence of both eyes to release the tension The tool is
上記の先行技術は、水晶体の厚さを変化させる毛様体筋や眼球を輻輳（内寄せ）させる内転筋などの過度の緊張が近視の原因であるとしている。そのため、その緊張を解くことが近視の治療になるとして、両眼球が対象物を見るために必要な輻輳（内寄せ）を少なくするようにプリズムを設置する向きを決めている。また、その他の従来の近視治療具もすべて毛様体筋の過度の緊張が近視の原因であるとしており、その緊張を解くことを目的としている。
しかし近視の本当の成因は現在でもはっきりせず、近視の原因は毛様体筋や内転筋の過度の緊張である、とした考えに基づいた今までの近視治療具は著しい効果を上げていない。According to the above prior art, myopia is caused by excessive tension such as ciliary muscles that change the thickness of the crystalline lens and adductor muscles that converge the eyeball. Therefore, assuming that releasing the tension is a treatment for myopia, the direction in which the prism is installed is determined so as to reduce the convergence (inward alignment) required for both eyes to see the object. In addition, all other conventional myopia treatment devices are considered to cause myopia due to excessive tension of the ciliary muscle, and the purpose is to relieve the tension.
However, the true cause of myopia is still unclear, and myopia treatment tools based on the idea that myopia is caused by excessive tension of the ciliary muscles and adductor muscles have been remarkably effective. Absent.
本発明も両眼の前にプリズムを設置するが、その際にプリズムの薄い方を内側（鼻側）に、厚い方を外側（耳側）する。 In the present invention, a prism is installed in front of both eyes. At this time, the thinner one of the prisms is on the inner side (nose side) and the thicker one is on the outer side (ear side).
両眼の輻輳（内寄せ）と水晶体厚の調節の間には輻輳反射と言われる反応関係が存在する。すなわち、両眼の輻輳（内寄せ）が強くなればなるほど近くの対象物を見ていることになるので、網膜上に明瞭な像を結ぼうとして水晶体厚を増す反応が生ずる。
本発明はこの輻輳反射の不具合に近視の原因を求め、これを正すことで近視の治療を行おうとするものである。輻輳反射の不具合とは、両眼が輻輳（内寄せ）して対象物を見ている時に、その対象物の距離の物を見るのに必要な水晶体の厚さよりもさらに厚くしてしまっているということである。そこでこの時、実際に見ている物が両眼の輻輳（内寄せ）で視線が交差している所よりも遠くの物を見ている状態にすれば、眼は今までその輻輳で用いていた水晶体厚よりも薄くしなければ網膜上に明瞭な像を結ぶことができず、眼はそのようにする。
このことを、図３を用いて説明する。Ａの位置にある対象物からの反射光がプリズムを通ると光路が外側に曲げられて眼球に入る。すると眼球にはＢの方向からの光が入ったようになりＢの方向に視線を向けるように輻輳（内寄せ）し、その輻輳に応じた水晶体厚にしようとする。しかし実際にはＡにある対象物から来た反射光を眼は見ているのであり、眼は水晶体を薄くしなければ網膜上に明瞭な像は結べず、その結果、眼は水晶体厚を薄くする。この様な状態が続けば、輻輳反射による水晶体厚の調節は今までよりも薄くなる方へと変化し、その結果近視が治癒してゆく。
前述のように、先行技術が輻輳（内寄せ）を弱めるようにしたうえで近くの物を見させるのに対し、本発明はまったく逆に輻輳（内寄せ）を強めたうえで遠くのものを見させようとする。
さらに本発明は先行技術がまったく注目してこなかった「輻輳反射の不具合を正す」という原理を用いており、先行技術では成し得なかった効果を有する。
なお、本発明は近視の者が通常使用している近視矯正眼鏡をかけたままの状態で使用しても効果が出る。There is a reaction relationship called convergence reflection between the convergence (inner focus) of both eyes and the adjustment of the lens thickness. That is, the closer the binocular vergence (inner alignment) is, the closer the object is being viewed, so that a reaction of increasing the lens thickness occurs in order to form a clear image on the retina.
The present invention seeks to treat myopia by finding the cause of myopia in the problem of convergence reflection and correcting it. The problem of convergence reflection is that when both eyes are converging and looking at an object, it is thicker than the thickness of the lens required to see the object at the distance of the object. That's what it means. So, at this time, if the object you are actually looking at is far away from where the line of sight intersects due to the convergence (inner focus) of both eyes, the eye has been used for the convergence until now. If it is not thinner than the lens thickness, a clear image cannot be formed on the retina, and the eyes do so.
This will be described with reference to FIG. When reflected light from the object at position A passes through the prism, the optical path is bent outward and enters the eyeball. Then, light from the direction B enters the eyeball, and the eyeball converges (inward) so that the line of sight is directed toward the direction B, and tries to have a lens thickness corresponding to the convergence. However, the eye actually sees the reflected light coming from the object in A, and the eye cannot form a clear image on the retina unless the lens is thinned. As a result, the eye has a thin lens thickness. To do. If such a state continues, the adjustment of the lens thickness by the convergence reflection will change to become thinner than before, and as a result, myopia will be healed.
As described above, while the prior art reduces the congestion (inner alignment) and allows nearby objects to be seen, the present invention, on the contrary, increases the congestion (inner alignment) and increases the distance (inner alignment). Try to show.
Furthermore, the present invention uses the principle of “correcting the problem of congestion reflection” that the prior art has not paid attention to, and has an effect that could not be achieved by the prior art.
It should be noted that the present invention is effective even when used in the state of wearing myopia correcting glasses normally used by myopic persons.
