i don't quite understand what u are trying to say...
are u asking if big eyes/small eyes can be inherited genetically from the parent? big bug eyes are common in Super Lesser/Butter's and small eyes are common in Lesser/Butter Pieds. i haven't heard of anything else proven genetic w/ eyes and other cases seem random.
or are u saying that your snake has different colored eyes? this would be paradoxing/chimerism i think and would be completely random.
