また、目の健康に対して、可視光線の青色領域(380~500nm)はエネルギーが強いため、網膜などに好ましくない影響を与える原因になると言われている。
しかし、この方法では多層膜の反射率が高く、レンズ内で強い多重反射を起こし、鮮明なゴースト光が視界に入ってしまう可能性がある。
また、本発明の態様に係る光学部品の製造方法によれば、レンズ内の多重反射を軽減し、見え易く、疲労、眼病予防にも効果的な光学特性を有した光学部品を提供することが可能となる。
なお、この形態は、発明の趣旨をより良く理解させるために具体的に説明するものであり、特に指定のない限り、本発明を限定するものではない。

また、本実施形態では、プラスチック基材2の屈折率(nd)としては、例えば1.50、1.60、1.67、及び1.74のうちから選択されたものが用いられる。なお、プラスチック基材2の屈折率を1.6以上にする場合、プラスチック基材2としては、アリルカーボネート系樹脂、アクリレート系樹脂、メタクリレート系樹脂、及びチオウレタン系樹脂等を使用することができる。
また、プラスチック基材2は透光性を有していれば透明でなくてもよく、着色されていてもよい。着色されたプラスチック基材2の透過率は、5~85%とすることができる。
プライマー層5は、プラスチック基材2とハードコート層6との密着性を良好にするためのもので、密着層として機能するようになっている。また、光学部品1に対する衝撃を吸収するためのものでもあり、衝撃吸収層としても機能するようになっている。

撥水撥油膜12の形成方法としては、ディッピング法、スピンコート法、スプレー法などの湿式法、あるいは真空蒸着法などの乾式法がある。
湿式法の中では、ディッピング法が一般的であり、よく用いられる。この方法は、フッ素置換アルキル基含有有機ケイ素化合物を有機溶剤に溶解した液中に、無機多層膜3,3’まで形成した光学部品を浸漬し、一定条件で引き上げ、乾燥させて成膜する方法である。
有機溶剤としては、パーフルオロヘキサン、パーフルオロ-4-メトキシブタン、パーフルオロ-4-エトキシブタン、メタキシレンヘキサフルオライドなどが使用される。
乾式法の中では、真空蒸着法がよく用いられる。この方法は、フッ素置換アルキル基含有有機ケイ素化合物を真空槽内で加熱して蒸発させ、撥水撥油膜12を形成する方法である。
また、光学部品の製造方法にあっては、このようなバランスのとれた優れた光学部品を確実に提供することができる。
