Experts disclosed that the young boy from China with strange-looking eyes is neither an alien hybrid nor a starchild.  Nong Yousui of Dahua in China’s Guanxi province has eyes like a Siamese cat’s and has night vision.

The story of Nong circulated in 2009 when it was reported the child’s sky-blue eyes has a night vision capacity. Accounts also surfaced that the boy’s eyes radiate a blue-green light in the dark when illuminated. A group of local reporters also claimed that Nong passed the test given to him while sitting in a pitch black room.

However, Live Science asks experts to explain Nong’s condition. According to doctors, he was born with a rare condition known as luekodermia. The boy’s localized luekodermia in his eyes makes him extra sensitive to light but allows him to see clearly in the dark.


Tapetum lucidum is retroreflector found in cats’ eyes (herrey.wordpress).


Nathaniel Greene, a physicist at Bloomsburg University of Pennsylvania said that night vision is made possible by tapetum lucidum. It is a layer of cells found in the eyes of cats and other nocturnal animals.

Greene said that the tapetum lucidum is retroreflector increasing the overall signal that hits the retina and enabling the animal to see in very low-light conditions.

But James Reynolds, a pediatric ophthalmologist at State University of New York in Buffalo, held that a functional tapetum in a human cannot materialize with just single hereditary transmutation.

Reynolds is quoted saying “Evolutionarily, mutations can result in differences that allow for new environmental niche exploitation. But such mutations are modified over long periods. A functional tapetum in a human would be just as absurd as a human born with wings. It can’t happen.”

Another explanation on Nong’s cat-eyes is mild case of ocular albinism. Optometrist and clinical researcher Adam Hickenbotham of University of California, Berkeley, ocular albinism causes lightly-pigmented irises and resulted to the boy’s trouble seeing in bright light.

Nong was brought a hospital when Nong Shihua, the boy’s father observed the boy’s bright blue eyes. But doctors assured him there was nothing wrong. The family observed that the boy strained to see in bright light but can see effortlessly without any light.
