I think conventional, established neuroscience can probably do that.

Of course, the 'with glutamate' part is a bit of a red herring, as we 
know that any other neurotransmitter would do just as well, being simply 
a way for one neuron to give its neighbour neurons a nudge.

(Actually, thinking about it, it's probably not a neurological thing at 
all. The most likely explanation is going to be that the cornea or lens 
of one eye is acting as a colour filter).
