You can of course visualise. Just have the feeling, too.

When I started with mobile awareness I had a picture in my mind - I could see an old-fashioned anatomy chart of the human body, and where my awareness was right now looked like the red dot of a laser pointer. So I moved this dot around with my mind, and I got energy work results.

Or when I learned sponging I visualised my body to be made of glass, but hollow, and visualised a sponge inside, moving around. That worked very well, too.

I moved my eyes with my energy work actions for a very long time.

So, visualisations are okay, moving the eyes is okay, but you do need to be also aware of the sensations.

Take care,
Oliver
