Evolutionary biologists have known for quite some time that our vision is far from perfect, but a new type of optical illusion is demonstrating just how many details we can lose in this manner. The differences between perception and reality can be staggering.Peripheral vision it the area in our field of vision that b... |

Scientists at Brown University say that life forms capable of sight – which include fish, birds, reptiles, mammals and so on – do not have brains that are innately hardwired to see. Rather, gaining sight is an active process that relies heavily on light itself. In order to demonstrate this, the researcher... |

Scientists were recently able to answer a centuries-old question, which sought to clear up an interesting thought experiment created by philosophers. They were wondering whether a person who was blind but recovered sight is able to distinguish visually between objects. The idea was that the formerly-blind person woul... |

Investigators analyzing the eyes of sharks have determined that the organs only contain a single type of cone cell, which means that the marine animals might in fact be color-blind. They are therefore completely incapable of sensing colors.This is weird, experts say, given that some of the closest genetic relatives t... |

It's a widely known fact that the brain, while indeed collecting all the stimuli it sees around us, only presents us with a minor fraction of those stimuli that spring into our conscious mind. When taking this into account, we are, in a sense, partially blind even before a doctor gives the verdict. A new scienti... |
