Abstract
Description
本出願は、2014年6月3日付で出願した日本国特許出願2014−115286に基づく優先権を主張するものであり、当該基礎出願を引用することにより、本明細書に含めるものとする。
本発明に係る光透過部を含む近視予防物品は、自然光及び人工光等の光の波長のうち、315nm超400nm以下、好ましくは360nm以上400nm以下の波長の紫外線を透過し、315nm以下の波長の紫外線を透過しない材料を光透過部に使用した物品であればよい。
本発明に係る、315nm超400nm以下、好ましくは360nm以上400nm以下の波長の紫外線を発する発光部を含む近視予防物品の具体例としては、照明器具(室内灯、車内灯、機内灯、街灯、電気スタンド、スポットライト等)、各種表示装置(たとえば、テレビ、パソコン用モニタ、ゲーム機、ポータブルメディアプレーヤー、携帯電話、タブレット端末、ウェアラブルデバイス、3D眼鏡、仮想眼鏡、携帯型ブックリーダー、カーナビ、デジタルカメラ、車内モニタ、航空機内モニタ等)に備えられる表示画面、近視予防のために使用される紫外線照射装置等が挙げられるが、本発明はこれらに限定されない。
本発明にかかる近視予防方法は、上記光透過部を含む近視予防物品を装着することである。装着方法は特に限定されず、近視予防物品の種類に従い、適切に装着すればよい。
近視予防に適した紫外線の特定方法は、315nm超400nm以下、好ましくは360nm以上400nm以下の範囲のうち所定の波長の紫外線が近視を予防できるかを調べる方法であって、その波長の紫外線をヒト又はヒト以外の脊椎動物に照射することを含む。そして、その波長が、実際に近視を予防できるかどうか、例えば、実施例2に記載の方法で調べる。これによって、315nm超400nm以下、好ましくは360nm以上400nm以下の範囲のうち、どの波長あるいはどの範囲の波長が特に効果が高いかを特定することができる。
315nm超400nm以下の波長の紫外線を透過し315nm以下の波長の紫外線を透過しない光透過部を含む近視予防物品として、有水晶体眼内レンズを例に、その近視予防効果を下記の試験によって検証した。
315nm超400nm以下の波長の紫外線を発する発光部を含む近視進行予防物品として、UVA照射装置を例に、その近視予防効果を下記の実験により検証した。
305nmにピークを有する光(図8)を、生後5日目のヒヨコに、2日間照射したところ、ヒヨコ角膜に上皮びらんが形成された。このように、当該光は組織障害性が強く、近視予防のために照射する光は、340nm以上であることが好ましく、350nm以上であることがより好ましく、360nm以上であることがさらに好ましい。
315nm超400nm以下の波長の光による近視抑制効果の実施のためには、当該波長の光を発する電灯とそれを通すレンズを有するメガネを合わせて使うことが有効である。
このように、315nm超400nm以下、好ましくは360nm以上400nm以下の波長の紫外線を眼が受けられるようにすると、その眼の近視発生を予防でき、近視の進行を遅らせることができる。
