以下に説明するように、本発明に係る光学製品に属するものとして、実施例1~3を作成した。又、実施例1~3と対比させるため、本発明に属さない比較例1~3を作成した。そして、実施例1~3及び比較例1~3のそれぞれに関し、可視領域における分光反射率特性の測定や、反射を防止してなお反射された反射光の各CIE表色系の色度図(x,y,Y)の測定、耐熱・耐汗・耐塩水・耐湿性能の評価等を実施した。
実施例1~3及び比較例1~3のレンズ基体はプラスチック製のフラットレンズとし、何れにおいても屈折率1.60のポリウレタン樹脂を用いた。これらのレンズ基体は、眼鏡プラスチックレンズ基体として用いることが可能であり、眼鏡プラスチックレンズにおける標準的な大きさとした。
図1(a)に、実施例1及び比較例1,2の分光反射率特性を表すグラフを示し、(b)にこれらにおける反射光のCIE表色系の色度図における各位置を表す図を示し、(c)に実施例2,3及び比較例3の分光反射率特性を表すグラフを示し、(d)にこれらにおける反射光のCIE表色系の色度図における各位置を表す図を示し、(e)に実施例1~3・比較例1~3における反射光のCIE表色系の色度図における各位置を表す表を示す。
次に、実施例1~3,比較例1~3の各レンズの密着性能につき以下に説明するような方法で評価した結果を、次の[表7]の上部に示す。
各レンズを浸漬させるために十分な量の市水をビーカーで沸騰させ、沸騰した市水の中でレンズを10分間浸漬させた後における膜剥がれの発生状況の確認を行った。当該確認の結果について、上記[表7]の「市水煮沸性能」の欄に示す。なお、膜剥がれが生じなければ「○」、生じれば「×」を付す。
各レンズをアルカリ性人工汗液に浸漬させ、20度に保たれた環境下で24時間静置し、24時間静置後にレンズを取り出し、水洗い後に表面状態変化の確認を行った。ここで、アルカリ性人工汗液は、ビーカーに塩化ナトリウム10g、リン酸水素ナトリウム12水和水2.5g、炭酸アンモニウム4.0gを入れ、純水1リットル中に溶かして作製したものである。当該確認の結果について、上記[表7]の「人工汗性能」の欄において、煮沸性能と同様に示す。
煮沸試験に対し市水を濃度4.5重量%の食塩水に代えた他は同様の内容の塩水煮沸試験を行った。1回目の煮沸時間を10分間とし、4回目まで繰り返し行った。当該確認の結果について、[表7]の「塩水煮沸性能」の行に、市水煮沸性能と同様に示す。
各レンズを60度・95%の環境に合計で1,3,7日間置いた際の変化に係る恒温恒湿試験を行い、更に7日おいた後のレンズの密着試験を上記と同様に行い、耐熱耐湿性能をみた。[表7]の「恒温恒湿性能」の欄において市水煮沸性能と同様に示すように、何れのレンズにおいても初期の性能を維持した。
以上によれば、性能(特に密着性能)に着目すれば、比較例2,3が不十分であり、比較例1がやや不十分であり、実施例1~3は十分である。一方、入射光や透過光に対して反射率がごく僅か(1%以下)であり反射光の彩度が非常に低いという光学特性の観点からは、比較例1,3は不満足で、比較例2や実施例1~3は満足である。従って、各種性能が良く前記光学特性の満足も得られるレンズは、実施例1~3であることになる。
