Chinese Boy with Ability to See in Pitch Black Stuns Medics

young Chinese boy who was born with beaming blue eyes has stunned medics with his ability to see in pitch black darkness.

Nong Yousui from Dahua, China has eyes that reflect neon green when light is shined on them. Doctors have studied Nong's amazing eyesight since his dad took him to hospital concerned over his bright blue eyes.

"They told me he would grow out of it and that his eyes would stop glowing and turn black like most Chinese people but they never did", his Dad said.

Nong enjoys playing outside with his schoolmates but experiences discomfort when in bright sunlight, however can see completely clearly in pure darkness.

To test his abilities, a Chinese journalist prepared a set of questionnaires which he was able to finish while sitting in a pitch black room. The tests show Nong can read and write perfectly without any light and can see as clearly as most people do during the day.

According to the World Record Academy (the leading international organization which certify world records), Nong has even set the world record for the first human who can see in the dark.

In animals, night vision is made possible by the existence of a thin layer of cells, called the tapetum lucidum. And like a Siamese cat, Nong's sky-blue eyes flash neon green when illuminated by a flashlight.

Nong's night vision has sparked interest around the world by vision scientists, evolutionary biologists, and genetic engineers. And this is good news for science as we may eventually be able to use genetic technologies to deliberately create such a condition ourselves.

A new and growing generation of extraordinary and gifted children are springing up across our planet.

Pupula Duplex (Eyes With 2 Pupils) What is Pupula Duplex

Pupula Duplex is a latin term which means double pupil. It is thought to be a condition where a person develops two irises, corneas and retinas on the same eyeball of each eye. This condition does not officially exist in official medical literature. Since there isn’t a great deal of evidence in the form of official literature supporting the existence of this condition, many people believe it is simply mythological It is often portrayed in science fiction literature. Although it is an extremely rare condition there are a few cases of famous historical figures who were born with this condition. This condition was given some credence when the famous Chinese emperor Liu Ch'ung was featured on Ripley’s believe it or not as having had this condition. It is thought to be condition that a person is born with. Since no official medical literature exists on this condition there is limited information available related to its possible causes? It is most likely a result of a genetic defect or mutation. It is not thought to be something that can be transmitted genetically. It isn’t contagious nor is it thought to be harmful to the person’s general health.
A common question that most people who encounter this condition are likely to ask are does a person with this condition see from pupils? Well before we can answer this questions let us briefly delve into how a person with normal eyesight sees.
When light enters the eye of a normal person it passes through the cornea. The cornea is the transparent front section of the eye that covers the iris. The cornea helps your eye to focus. The light then approaches the other side of the cornea called the aqueous humor then it passes through the pupil or the iris. The iris contracts or dilates depending on the amount of light that may be present hereby increasing or limiting the amount of lie that progresses deeper into the eye. The light then travels through the lens that is responsible for focusing the light. This focused light is then transported to the center of the eye covered in a clear jelly called vitreous which is surrounded by the retina.
The light is picked up by the photoreceptors in the retina where it is projected unto a flat and smooth surface. Signals are then sent from the photoreceptors to the optic nerve where it is translated into electromagnetic signals where its then sent to the visual center of the brain for interpretation.
A person who has a double pupil may have the ability to increase the volume of visual information that is taken in when he sees. His focus may also be vastly improved. It is highly unlikely that this person will see separately in the same eye as the information will travel from the same photoreceptors in that particular eye. Since this condition has not been studied in any great detail it is not well understood how the brain would interpret the information sent by the eye of a person with a Pupula Duplex.
