科普專欄–薯不揀單 - 三十秒科學–藍眼睛

膚色、髮色及瞳孔顏色均是由黑素細胞(Melanocyte)所產生的黑色素(Melanin)而定。495Please respect copyright.ＰＥＮＡＮＡkJ7psGjXbW
然而，負責膚色髮色與負責瞳孔顏色的黑素細胞卻有著一道顯著不同的分別。495Please respect copyright.ＰＥＮＡＮＡlC9TC9Z0OU

（圖2）黑素細胞所產生的黑色素，會儲存在名為黑色粒子的細胞器官裡頭。495Please respect copyright.ＰＥＮＡＮＡJP0sKLty6Z

位於皮膚下的黑素細胞，會釋出黑色粒子到髮囊及皮膚細胞，賦予皮髮顏色。495Please respect copyright.ＰＥＮＡＮＡxZf6efoPsM

而位於虹膜(Iris)的黑素細胞，則不會釋出黑色粒子到細胞外部，而是把它儲存在細胞內。495Please respect copyright.ＰＥＮＡＮＡUlRl9IL0Lf

（圖3）當光線進入眼睛的虹膜，內部蛋白質所折射及吸收的波長便會呈現出瞳孔的顏色。495Please respect copyright.ＰＥＮＡＮＡNwlnrmJptt

瞳孔之所以呈藍色，並不是有著藍色素的物質，而是純粹因為虹膜內的黑色素稀少，最終折射出藍色波長的光線。495Please respect copyright.ＰＥＮＡＮＡWIqw1mkdyq

虹膜越多黑色素的話，瞳色便會越漸啡黑。495Please respect copyright.ＰＥＮＡＮＡykDEUz1XY1

而患有白化病(Albino)的人士，基於缺乏黑色素，光線折射出眼睛內血管的顏色，因而呈粉紅色狀。495Please respect copyright.ＰＥＮＡＮＡAEwPV94uHc
