Felt sense vs visual sense

Meditation instructions generally reiterate focusing ones attention on the sensations of breath but attention can mean several things. It can mean placing attention on what you feel but what about what you see? What I notice a lot is, what I can only describe as my "inner eye", wants to see or visualise something so it generally sees various images either from the past or fantasises about the future etc which is very distracting. Where am I meant to place this eye? I don't know how to just not see anything. I can place my attention on the sensations of my abdomen rising and falling but that is a felt sense not a visual sense. I have not come across any instruction about this. Do I place the visual sense on the abdomen? Or do I visualise an object or Buddha etc?
