convergence

Many neurons converging onto one neuron, mainly in the eye, is an amazing process and a potential life saver.  Convergence in the eye takes place where our peripheral vision is, which in turn is a potential life saver because without peripheral vision, human beings would be more vulnerable.  This amazes me because convergence does not take place in the fovea, the area in the eye mostly used for color and the focal point of the eye, because it is simply unnecessary.  I'd rather see color on a neuron ration of 1:1 instead of having many different color neurons firing on one cone because then no colors would be consistent.  More so, convergence in the rods is to detect movement or some low light colors that lie in the peripheral so that we can be notified of the object and turn our heads to look at it.  We are not supposed to see clear, colorful images from our peripheral, but I think that would be awesome.
  
Now my vision is horrible, about 20/400 or something crazy like that, so I always wonder what other people are seeing and how accurate, because even with my contacts and glasses, I still need to squint.  I wonder, does my near-sighted vision also affect and lessen my peripheral vision, and do my contacts and glasses restore the weaknesses?  Or am I just more vulnerable to sneak attacks than the average human being?  Imagine if peripheral glasses were made so that one's peripheral vision could increase and expand.  Heat seeking glasses and night vision glasses were created and they are beneficial for military and combat, and I also think that expanding peripheral vision so that a greater range can be visible would also be beneficial.
