Pupula duplex is a Genetic Defekt and happened to a Human only 1 time before. In a Old legend there is a warrior with 2 Pupils. This phenomen was described as a sign of force and pain. Nowdays there are no verified founds of the pupula duplex syndrom so nobody knows what the causes are. Therefore no one knows if people with this syndrom are blind and we dont know if we can heal them. Also we dont think its possible to cure pupula duplex or help the humans with the syndrom. The pictures on the web that you can find are all done with Photoshop and are Fake.
Dont relay on informations or pictures on the internet because thy are most fake.
