Pupula Duples is latin for double pupil. It is thought that a person develops two irises, corneas and retinas on the same eyeball of each eye. It is extremely rare, some people believe this it is simply mythological but a few people have been born with the condition and even historical figures were born with the condition.A chinese emperor Liu Ch'ung featured in Ripleys believe it or not. It is though this is the result of a genetic defect or mutation.It is not harmful to a persons general health. This condition has not been studied as it is very rare.
When light enters the eye it passes through the cornea. The cornea helps your eye to focus. The light approaches the other side of the cornea (aqueous humor) then passes through the pupil or the iris. The iris contracts or dialates depending on the amount of light. The light travels through the lens that is responsible for focusing the light. The focused light is then transported to the center of the eye called vitreous which is surrounded by the retina.The light is picked up by the photo receptors in the retina. Signals are sent from the photo receptors to the optic nerve where it is translated into electromagnetic signal, it is then sent to the visual center of the brain for processing.A person who has pupula Duplex may be able to increase the volume of information that is taken when he sees, the focus may also be improved.
