Persistent Afterimages. Doctor to visit?

I have been seeing persistent afterimages for a long time and it is not limited to phone, tv, laptop. For ex: I watch a plate, glass, grill, plaster of paris design and look away I see a glimpse of that object for a second. I am working on my laptop and I see it towards the screen after typing then I see the keyboard glimpse. Even on the road if there is a bright sign board or name and I look away, I see a glimpse of that. I have got my dilated retina exam done and it is fine. Even a few months ago I got an MRI Brain Plain done on the suggestion of a neurologist and it's also fine. Recently optho doctor suggested that I go for a Neurologist for ocular migraine. I don't have any headache but sometimes I feel heaviness on the sides and back of my head. I also have many times feel pain in the eyes area. I have lazy eye in LE, floaters, number in both eyes. Taking Bilypsa and L-gautholine for fatty liver from 7 months. Lost 26 Kg of weight in 7 months. Which doctor to visit? I am fed up.
