At What resolution our Eyes see, Megapixels, Frames per Second, read on...?
If our Vision were to be converted ito digital photography or a Video,
1) Wht is the Raw Resolution and megapixels our Eyes see at ?
2) How many Frams per Second
3) If one Frame of our Vision would be converted into a Digital photo, wht wud be the size of the file ?
4) If our eyes see at so high resolution, why can't we Zoom in, or must i say Like see some thing which is far very Clear, In more Detail ? Because in a Digital photo if when zoom in, we can see better if the Picture is of higher resolution.
5) By any Modification in the cells of the eyes, do u think in near future we are goin to get night vision if we want ?
6) why cannot a complete eye be transplanted from one person to another?
7) Suppose if we had black and white vision, wud u like it ? ![]()
8)if we cud see Ultra violet radiation or far infra red radiation, wht wud the colour be like?

1)The average human eye, in the fovea (the sweet spot) in bright light, can distinguish 1 arc minute (1 degree/60) in luminance (black/white) difference. About 2 arc minutes (1/30 degree) for a red/blue or other chrominance difference at roughly the same brightness.
If you sit 20" from monitor (I do), then your central vision can see two .006" black dots seperated by .006" of white. (your peripheral vision is nowhere near this good) A 19" monitor with 18" visible has a 14.4" horizontal viewable line. You could see about 2500 pixels across that screen, if they were black/white/black/white, and if your shadow mask allowed it, and if your convergence were good enough, etc. About 1250 colored dots.
2)Generally everyone agrees that it is not higher then 30 fps for the human eye.
3)The eye is not a single frame snapshot camera. It is more like a video stream. The eye moves rapidly in small angular amounts and continually updates the image in one's brain to "paint" the detail. We also have two eyes, and our brains combine the signals to increase the resolution further. We also typically move our eyes around the scene to gather more information. Because of these factors, the eye plus brain assembles a higher resolution image than possible with the number of photoreceptors in the retina. So the megapixel equivalent numbers below refer to the spatial detail in an image that would be required to show what the human eye could see when you view a scene.
Based on the above data for the resolution of the human eye, let's try a "small" example first. Consider a view in front of you that is 90 degrees by 90 degrees, like looking through an open window at a scene. The number of pixels would be
90 degrees * 60 arc-minutes/degree * 1/0.3 * 90 * 60 * 1/0.3 = 324,000,000 pixels (324 megapixels).
At any one moment, you actually do not perceive that many pixels, but your eye moves around the scene to see all the detail you want. But the human eye really sees a larger field of view, close to 180 degrees. Let's be conservative and use 120 degrees for the field of view. Then we would see
120 * 120 * 60 * 60 / (0.3 * 0.3) = 576 megapixels.
The full angle of human vision would require even more megapixels. This kind of image detail requires A large format camera to record.
4)because our brains are mostly wired for survival and part of that mechanism involves viewing many objects at once and distinguishing if they are a threat.
5)i dont think we will have that technology for at least 100 years so that does not qualify as the near future. and also when this is available, i would think that the government would make it only available to its own agencys.
6)the first successful human eye tranplant was completed on April 22, 1969
7)i know some color blind people, and they are all mentally derranged. im not being critical or mean, they just are seriously crazy. so no i dont think i would like it.
8)ultra violet light looks a desaturated (whiteish) blue. infra red vision would be like when the predator trys to kill danny glover.
hope that helps
