I can only think of one answer. As the zygote grows, a somatic cell mutation occours in one of the cells which will eventually continue to divide forming the left eye. This line of mutant cells could have a different pigmented protein which colours the iris-making the "mutant-eye" green. The other eye however developed from a normal cell line without the mutation making it blue.
That's the only answer I can find... but the probability of this occouring must be small since a mutation like this would be rare. But this is'nt that rare a condition.
