the eyes have two sorts of cells :
The cones which allow the distinct and colored vision. They are located on a small place of the eye called the fovea. These cones are wired to the optical nerve ONE by ONE and are the rel pixel of sight. In order to distinguish 2 points the light emitted by these points must project their images on two Different cones . So ,the eyes can separate 2 points separated by one minute of arc (about 1mm at 1m) .
Different are the other types of cells the rods which are relied by packs to the optical nerve. They have a very low accuracy to distinguish the details but allows to see when the light emitted by an object is very low. They do not permit to see the colors, so when you use these cells at the fall of the night you can see objects but not the colors

You have cells called rods that can detect light and cells called cones that can distinguish color, Your brain puts the picture together, from the patterns of how light falls on them.

actually our eyes don,t have any pixels.they are present in a catching lenses.so eyes don't have any pixels.
good question.........
