Just as a High resolution computer monitor may have a resolution of 1,920 x 1,440 and a refresh rate of 90 frames per second, thus processing a total of 248,832,000 (1,920 X 1,440 X 90)individual pieces of information every second, human eye will process a FAR higher amount of information. What I'm wanting to try and quantify is just how information is being process ed by the eye(s) each second. I need the following from an RECOGNISED authoritative source: 1. Horizontal resolution of the eye 2. Vertical Resolution of the eye 3. Frames per second Ideally I will be able to get answers to all of the three questions but will settle what is available. |

I have a hazy recollection of a Scientific American article that addressed human eye resolution. This was probably in the 1990's. Sorry I cannot be more sepcific, but a visit to their website might be a starting place for you or a Researcher. |

Another random comment to help for a starting point: The human eye does not process as quickly as a computer monitor. I believe it's around 30 fps, though I don't know about resolution. |

An interesting question! I don't have the answer, but here are a few comments: 1) unlike a computer screen, the spatial resolution of the retina of the human eye varies. As I recall, there is a relatively small spot at the focal point which has quite high resolution, and the rest of the retina has much lower resolution. While we usually think that we can see at high resolution across our entire field of view, this is an illusion that our brains put together. You can easily test this by trying to read something without looking directly at it. 2) The time resolution (frame rate) of the eye can be roughly determined (as noted by alerys-ga) by the frame rate required for projected film or a computer monitor to give the illusion of motion. 30 frames per second is often used in video, so the frame rate of the human eye must be somewhat less than that. 3) The brain commonly discards much of the information potentially available, and focuses on only a small part of it. If you can find out the resolution and frame rate of the eye, that will give you the maximum "hardware" information rate. But the maximum rate for information to be transferred to the brain, or processed by the brain, is likely less than the "hardware" maximum. |

http://www.viperlair.com/articles/archive/editorials/fps.shtml That will explain everything. It takes a few moments for the page to load. As for the refreshrate of the eye. It is a constant feed, there is no need for a pause to collect data. |
