A young Chinese boy who was born with brilliant blue eyes -- like those of a Siamese cat -- claims to have the ability to see in pitch darkness, the Daily Mail reported.

Nong Yousui from Guangxi's Dahua village has eyes which reflect neon green when a light is shined on them.

Nong, who enjoys playing outside with his schoolmates but struggles with bright sunlight, claims he can see perfectly clearly even in complete darkness.

In animals, night vision is made possible by the existence of a thin layer of cells, called the tapetum lucidum.

James Reynolds, a pediatric ophthalmologist at State University of New York in Buffalo, suggests Nong simply has extremely good eyesight rather than true night-vision.

男孩長貓眼可“夜視”

???????據英國《每日郵報》報道，一位中國小男孩天生就擁有一雙如同暹羅貓眼般亮亮的藍眼睛，在黑暗中也能看見東西。

???????農有穗家住廣西大化村。用手電筒照的時候，他的眼睛就反射出氖綠色的光芒。

???????農有穗很喜歡和同學們在室外玩耍，但陽光強烈的時候就不太舒服，在完全黑暗的環境里卻能看得非常清楚。

???????據悉，有些動物之所以能夜視，都是因為有了一層薄薄的反光膜。

???????布法羅紐約州立大學小兒眼科醫師詹姆斯·雷諾茲表示，農有穗擁有的不過是超好的視力，而非真正的夜視能力。
