How to create eyes tracking / reflection on array object

I try to create the eyes tracking and reflection of the eyes effect on array object.
like it have many eyes array near to each other and have some point that is the attractor to all of the eyes to tracking to it like an human eyes ball 

So.....

- how can I create eyes tracking to point or object effect on arrayed geometries

- after that how can I create an eyes reflection effect from project the grid line onto the surface of the object and distance between the point on the eyes and the grid line that project on the eyes.

I also attached the sketch and rhino screen so you can see a better picture what I want to do.

thanks.
