How can I make an armature for eyes? I am struggling with setting bones of eyes in a model. I followed some eye riggings tutorials and applied it on my model. 

I can change the direction of eyes with IK's. And when i rotate my model's head, eyes follow the position properly. However when i move another bone like hip bones, eyes moves non-propotional to head. They move fastly. How can I arrange that?

Here is what i did:

i added two bones to both of eyes. and added their IK's. Then i connected the eyes ('n object mode) to bones (in pose mode) with bone choice. Lastly i connected both bones of eyes to head bone with keeping offset.
okay i solved the issue. i deselect vertex groups of eyes in armature section at modifier tab. know eyes move as they should be. maybe this helps others who struggle with same problem.
