万能な眼をもつペンギン

とても寒い南極を中心とした島々にオウサマペンギンは暮らしている。彼らの眼の構造は、氷の上での生活に適応している。キラキラした氷の眩しさ、エサを採るために潜る暗い海、二つの世界を行ったり来たりして生きているペンギンの眼は、他の鳥たちとは全く違う。昼間は、オウサマペンギンの瞳孔は、小さな四角い穴のように縮まる。しかし、エサを採るために暗い海で泳ぐとき、彼らの瞳孔大きく丸く広がる。ひとみの大きさと形の変化により、ペンギンはサングラスなしでも眩しさを感じない。さらに、ライトを持たずに暗い海の中でも、エサを見つけることができる。

防御・安定:: 耐光、調光

自然との共生

オウサマペンギン眼のようなコンタクトレンズを作ることができれば、様々な視力障害を持つ人の生活に役立つ可能性がある。例えば夜盲症の場合は、「暗いところで見にくい」という症状を改善できるかもしれません。また昼盲と呼ばれる「明るいところで見にくい」という症状も改善できる。彼らの眼の構造は、新しい視力検査の機器開発に役立つかもしれない。明暗がどの程度分かるかという検査機器です。白内障という眼の病気の早期発見や、手術後に患者さんの視力が変化したかどうかなど現在より一歩進んだ視力検査に役立つ。
