【発明の詳細な説明】
〈産業上の利用分野〉
本発明は雪山、スキー場、海岸などの自然光の強い場所

内などで使用される可視光線を遮光し紫外線を透過させ
る機能を有する遮光し、ンズに関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention is used in places with strong natural light such as snowy mountains, ski resorts, and beaches, as well as in health clinics and beauty salons using artificial light sources. It relates to a light shielding lens that has the function of transmitting light.
〈従来の技術〉

せる。<Prior art> It is known that when the eye tissue is exposed to radiation, it causes eye damage, and visible light wavelengths of 410 nm to 4
The region around 80 rv is considered to be a band with a high degree of retinal damage, and the area that has the greatest effect is blue light in the vicinity of f% 430 nm to 440 tv, which is called blue color damage and causes retinal damage.
従来、遮光効果を奏するためにレンズの染色や光線吸収
膜の形成などの手段により遮光レンズを製造していた。Conventionally, light-shielding lenses have been manufactured by dyeing the lenses or forming light-absorbing films in order to achieve a light-shielding effect.

に提案されている。For example, a synthetic resin lens with an ultraviolet absorber added to provide an ultraviolet shielding effect was developed in 1973.
14452, and furthermore, for the purpose of fashionability and ultraviolet shielding, a synthetic resin lens is produced by adding a benzophenone ultraviolet absorber and a coloring agent to a monomer mainly composed of diethylene glycol bisallyl carbonate, and then heating and polymerizing it. This is proposed in Japanese Patent Publication No. 52-150492.
（発明が解決しようとする問題点）
しかしながら、前記の紫外線吸収剤と染色による遮光レ
ンズは、紫外線全域（波長的４００ｎｍまで）の遮光を
対象としているためこれらの遮光レンズからなる従来の
サングラスを装用して、スキーや日光浴等を行なった後
、サングラスをはずすと、顔にサングラスの跡が残って
しまうという欠点があった。すなわち、眼のまわりだけ
が白く、雪焼けや日焼けのないままになってしまい、不
自然な感じになる。(Problem to be Solved by the Invention) However, since the above-mentioned light-shielding lenses made of UV absorbers and dyeing are aimed at blocking the entire range of ultraviolet rays (up to 400 nm wavelength), it is difficult to wear conventional sunglasses made of these light-shielding lenses. However, when you take off your sunglasses after skiing, sunbathing, etc., you end up leaving marks from the sunglasses on your face. In other words, only the area around the eyes is white and there is no snowburn or sunburn, giving an unnatural look.
ところで日焼（プや雪焼は等の肌焼けについては、一般
に２つに分類して考えることができる。ひとつは紅斑効
果といわれる皮膚が赤くなる現象（皮膚の赤化）であり
、これは２８０〜３２０ｎｍ付近の波長の紫外線が作用
する。もうひとつは色素沈着といわれる皮膚が黒くなる
現象（皮膚の黒化）であり、これは３２０〜４０Ｑｒ＋
ｍ付近の波長の紫外線が作用する。肌焼けについてはこ
れら２つの効果が同時に作用しているとされている。By the way, skin tanning (such as sunburn and snowburn) can generally be classified into two types. One is the phenomenon of reddening of the skin (reddening of the skin) called the erythema effect, which is caused by 280 Ultraviolet rays with a wavelength around ~320 nm act.Another phenomenon is called pigmentation, which causes the skin to darken (skin darkening).
Ultraviolet rays with wavelengths around m act. It is said that these two effects act simultaneously on skin tanning.
肌焼は直後の皮膚は赤いが２〜３日後には落ち着いた黒
い（茶色い）皮膚になるということは紅斑効果が短時間
で消えた後も色素沈着は長い間続けて見られるからであ
る。紅斑効果は皮膚の炎症のひとつと考えることができ
る。Immediately after skin tanning, the skin is red, but after 2 to 3 days, the skin turns black (brown) because pigmentation continues for a long time even after the erythema effect disappears in a short time. The erythema effect can be considered as a type of skin inflammation.
従って紫外線には紅斑効果と肌焼けに関係しているもの
があり、これらは分けて考えることができる。すなわち
、２８０〜３２０ｎＩｎの波長の紫外線については、皮
膚の炎症のひとつである紅斑効果に作用する。また、３
２０〜４００ ｎｍの波長の紫外線については、肌焼け
にとって必要不可欠な光線であると言える。Therefore, there are UV rays that are related to erythema effects and skin tanning, and these can be considered separately. That is, ultraviolet rays with a wavelength of 280 to 320 nIn act on the erythema effect, which is one type of skin inflammation. Also, 3
Ultraviolet rays with a wavelength of 20 to 400 nm can be said to be essential for skin tanning.
外線の選択的透過ができないこと、また、光線反用膜で
は、光線反射帯域を広くとりにくい等の問題があった。There are problems such as the inability to selectively transmit external light, and the difficulty in achieving a wide light reflection band with a light-reversing film.
また特開昭５０−１４４５２号公報や特開Ｉｌｌ ５２
−１５０４９２号公報に示す染色による遮光方法により
レンズを染色すると可視光Ｆｌｌ域の透過率は低下する
が、例えば茶系色や灰系色等の染色をした場合同時に紫
外線域の透過率も低下する。Also, JP-A-50-14452 and JP-A-Ill-52
If the lens is dyed using the dyeing light shielding method described in Publication No. 150492, the transmittance in the visible light Fll range will decrease, but if it is dyed, for example, in brownish or grayish colors, the transmittance in the ultraviolet range will also decrease at the same time. .
これは一般的に染料の調合時、赤、量系の染ｒ１を使用
し、茶系色用、灰系色用染料を作成しているため、紫外
線域に近い可視光線である青系色や紫系色を染色するこ
とから紫外線域までに染色の影響が及んでしまうからで
ある。This is because when mixing dyes, red and quantity-based dyes R1 are generally used to create dyes for brown and gray colors. This is because since dyeing is done in a purple color, the effects of the dyeing extend to the ultraviolet range.
例えば、染色によって可視光線透過率を低減させた場合
、茶系色染色で可視光線透過率が５５０ｎｍ付近では６
５％の場合、紫外線域内の光波長３３Ｑｎｍ付近では、
透過率は７％程度になる。For example, if the visible light transmittance is reduced by dyeing, if the visible light transmittance is around 550 nm with brown dyeing, the visible light transmittance will be 6.
In the case of 5%, at light wavelength around 33Qnm in the ultraviolet range,
The transmittance will be about 7%.
従って、紫外線の波長３２０ｎｍ〜４００ ｎｍ付近を
透過させ、かつ、可視光線の波長４３５ ｎｍ付近を効
果的に遮光させるような透過率曲線を有する遮光レンズ
を得ることはできなかった。Therefore, it has not been possible to obtain a light-shielding lens having a transmittance curve that allows ultraviolet light with a wavelength of around 320 nm to 400 nm to pass therethrough and effectively blocks visible light with a wavelength around 435 nm.
本発明はこのような問題点を除去するためになされたも
のであり、雪焼けや日焼りを起こす紫外線を透過させ、
同時に可視光線の眩しさを防ぐための遮光機能を有した
遮光レンズを提供することを目的とづるちのである。The present invention was made to eliminate such problems, and it transmits ultraviolet rays that cause snowburn and sunburn.
At the same time, the objective is to provide a light-shielding lens that has a light-shielding function to prevent glare from visible light.
〈問題点を解決するための手段〉
上述の本発明の目的は、ジエチレングリコールごスアリ
ルカーボネートを主成分とするモノマーを重合して得た
合成樹脂レンズを、青米色分散染色溶液に浸漬、染色加
工し、次に高屈折率膜と低く但し、ｍはＯまたは１の整
数、４３０ ｎｆｆ１≦λ≦５００ｎｍ）となるように
順次積層し、コーテイング膜を形成させたことを特徴と
する遮光レンズによって達成された。<Means for Solving the Problems> The object of the present invention described above is to dye a synthetic resin lens obtained by polymerizing a monomer mainly composed of diethylene glycol and sallyl carbonate by immersing it in a blue rice color dispersion dyeing solution. This is achieved by a light-shielding lens characterized by forming a coating film by sequentially stacking a high refractive index film and a low refractive index film (where m is an integer of O or 1, 430 nff1≦λ≦500 nm). It was done.
本発明の遮光レンズの製造においては、ジエチレングリ
コールビスアリルカーボネートを主成分とする七ツマ−
を重合して得た合成樹脂レンズを使用し、先ず該合成樹
脂レンズを青系色染料分故溶液に浸漬して染色加工する
。In the production of the light-shielding lens of the present invention, a diethylene glycol bisallyl carbonate as a main component is used.
A synthetic resin lens obtained by polymerizing is used, and the synthetic resin lens is dyed by first immersing it in a blue dye separating solution.
青系色染料としては、例えば三菱化成製ダイアニツクス
ブルーＲＮ−Ｅや三菱化成製ダイアニツクス ターキ
スブルーＢ−ＦＳなどの青色系染料を使用する。As the blue dye, for example, a blue dye such as Dianix Blue RN-E manufactured by Mitsubishi Kasei and Dianix Turkey Blue B-FS manufactured by Mitsubishi Kasei is used.
その理由は、合成樹脂レンズを青系色に染色寸る場合、
可視光域では５８５ ｎｍ付近に透過率の減少が見られ
るが、紫外線域ではその染色による影響を受けることが
少ないという特性のためである。The reason is that when dyeing synthetic resin lenses in a blue color,
This is because in the visible light range, a decrease in transmittance is seen around 585 nm, but in the ultraviolet range it is less affected by dyeing.
一般に無色の合成樹脂レンズの紫外線透過率は３８０ｎ
ｍで８８％程度である。これに対し、ダイアニツクス
ブルーＲＮ−Ｅを濃度８５％（透過率１５％）に染色し
た場合、可視光線域の５８５ｎｍで透過率は１７％であ
るのに対し、紫外線域３８０ｎＩＩｌで７８％程度とな
っている。Generally, the UV transmittance of colorless synthetic resin lenses is 380n.
m is about 88%. On the other hand, Dianics
When blue RN-E is dyed to a density of 85% (transmittance 15%), the transmittance is 17% in the visible light range of 585 nm, while it is about 78% in the ultraviolet range of 380 nIIl.
ところが、この染色したレンズでは、上記目的を達成す
るには遮光率の点で不十分である。これは可視光域に含
まれる４００〜５００ ｎｌｌの波長域の光の遮光率が
低いためである。このレンズを使用した場合、雪山、ス
キー場等では眩しく感じる。However, this dyed lens is insufficient in terms of light shielding rate to achieve the above objective. This is because the light shielding rate for light in the wavelength range of 400 to 500 nll included in the visible light range is low. When using this lens, you will feel dazzling on snowy mountains, ski resorts, etc.
またこのレンズの使用は色調が青いために、物の見え方
が不自然に感じられ、長時間装用し、サングラスをはず
した後に感じる、周囲が赤っぽく見えるといった残像現
象も問題となってくる。Additionally, the blue color of these lenses makes things look unnatural, and after wearing them for long periods of time, after taking off the sunglasses, the surroundings appear reddish, which is a problem. .
そこで遮光率を高くし、同時に自然な色の見え方で残像
現象を起こさせないレンズの色調は灰系色であり、それ
に近い茶系色が好ましい。Therefore, the color tone of a lens that increases the light shielding rate and at the same time provides natural color appearance and does not cause afterimage phenomenon is a grayish color, and a brownish color similar to that is preferable.
茶系色、灰系色は、その分光透過率が可視光域のほぼ５
００ｎＩｌｌ〜６２０ｎＩｌｌの波長域において、太陽
光とほぼ同様にフラットな透過率曲線の変化を示し、自
然光と近い透過率曲線の変化を示しているのでカラーバ
ランスを損わなく優れている。The spectral transmittance of brownish and grayish colors is approximately 5 in the visible light range.
In the wavelength range of 00 nIll to 620 nIll, the transmittance curve exhibits a flat change almost similar to that of sunlight, and the change of the transmittance curve is close to that of natural light, which is excellent without impairing color balance.
しかし、前記従来の技術で述べたように、灰系色、茶系
色の染料で上記目的を満足するものは見当らず不可能で
ある。したがって、上記目的を解決するためには染色だ
けでは不十分である。However, as described in the prior art section, it is impossible to find any gray or brown dye that satisfies the above objective. Therefore, staining alone is not sufficient to solve the above objectives.
そこで、次にプラスチックレンズの表面に高屈折率物質
と低屈折率物質とを交互に蒸着する。そＯまたは１の整

−／４が好ましく、また蒸着物質の積層方法は、特に真
空蒸着が好ましいが、イオンスパッタリング法等も可能
である。Therefore, next, a high refractive index material and a low refractive index material are alternately deposited on the surface of the plastic lens. O or an integer of 1, 430nm≦λ≦500nIIl), especially λ
-/4 is preferable, and vacuum evaporation is particularly preferable as the method for laminating the evaporation material, but ion sputtering and the like are also possible.
遮光のための積層膜に用いる高屈折率膜用物質には、酸
化ジルコニウムが特に好ましく、酸化チタン、酸化セリ
ウム、酸化インジウム、酸化ネオジウム及び酸化タンタ
ルも使用できる。また低屈折率膜用物質には、酸化硅素
が特に好ましく、フッ化マグネシウムも使用できる。Zirconium oxide is particularly preferred as the material for the high refractive index film used in the laminated film for light shielding, and titanium oxide, cerium oxide, indium oxide, neodymium oxide, and tantalum oxide can also be used. Silicon oxide is particularly preferred as the material for the low refractive index film, and magnesium fluoride can also be used.
積層させる順番は、高、低、・・・・・−高、低の順で
あっても低、高、・・・・・・低、高であってもよく、
その層数は、４〜２０層が好ましく、合計の層の数が少
なくなると、反射する波長域の幅は広がり、全体的にな
だらかな反射帯域を示し、合計の層の数が多くなると、

方が急峻になる。The order of stacking may be high, low, ...-high, low, or low, high, ...low, high,
The number of layers is preferably 4 to 20, and as the total number of layers decreases, the width of the reflected wavelength range widens, and the overall reflection band shows a gentle reflection band, and as the total number of layers increases,

顕著となり、透過率曲線の最小値域を表わす谷の両側の
透過率曲線の傾斜が急になる。In particular, when the total number of layers increases from 10 to 14, this effect becomes more pronounced, and the slope of the transmittance curve on both sides of the valley representing the minimum value region of the transmittance curve becomes steeper.

化した広い範囲を遮光帯とした反射膜が形成できる。For example, as shown in Figure 1 below, the transmittance is 10 to 20%.
If the valley is formed near 470 nm, the transmittance curve will have a steep slope below 470 nIIl, especially at 38 nm.
At around 0 nm, the transmittance is about 78%, which is exactly the same as the transmittance curve shown by a diethylene glycol bisallyl carbonate plastic lens. Also, the number of layers and the reflected wavelength range are inversely proportional, and the magnitude of the anti-f:F1 ratio is proportional. Also, the specific wavelength range mentioned above is rejected! For 8"g films, when two or more different films that reflect specific wavelength ranges are stacked and deposited, the specific wavelength ranges are added to form a reflective film that has a wide area as a light-shielding band. can.
