It is like watching an X-Men episode, where a child was discovered to possess extraordinary powers no ordinary person can do.
A video featuring a boy in China with the ability to see in the dark had been making its round in the web. Nong Yousui from Dahua, China has sky-blue eyes that flash neon green when illuminated by a flashlight. It is reported that he can see clearly in a pitch black room. Reportes in the video even asked the boy to fill-out a questionnaire in a pitch black room and acted surprised that he was able to do so.
Experts say that Nong does have unusually colored irises, but do not agree that he is the next step in human evolution.
Tapetum Lucidum is a layer of cells in the eyes of noctural animals that makes night vision possible. It is a “retroreflector” that reflects light back when a beam of light hits it. This amplifies the overall signal and allows an animal to see in low-light conditions. This is also what causes a cat’s eyes to flash neon green when they are lit up at night. Experts suggest that Nong’s eyes should do the same if he actually does have catlike eyes.
Unfortunately, the video failed to show that Nong’s eyes flash neon green when light was shined on them. James Reynolds, an expert opthalmologist at State University of New York said, “A video could capture [eyeshine] easily, just like in nature films of leopards at night.” The video of Nong does not.
Reynolds added that evolution happens incrementally. It doesn’t just happen. A single mutation cannot produce a fully formed and functioning tapetum lucidum all at once.
“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,” Reynolds stated.
It is possible that he may still have good night vision even if he does not have true cat eyes. However, it is hard to know unless an expert performs test on him.
Dennis Brooks, professor of opthalmology at University of florda’s College of Veterinary Medicine said,”A good ophthalmic examination by a physician ophthalmologist is in order, I think.”
