OP used that word, but it is clear from context that they are referring to the target of gaze (which is also what a properly working eye focuses on), rather than the specific processes that go on in focusing. | |

So still a small fraction around 1/60th area of the whole view is in focus at any one time. You mentioned that the "attention" is limited to small section of visual field, can we say that its limited to 1/60th of the visual field? So to say some entity is in attention is in the fovea as we are focusing on it? | |
