Sometimes i feel slight vibrations in my side vision or when iam focused on a point i see them in my side view (stops when i look around). They are  also noticeable in light as well as in low light. Specially straight lines seem to to be more noticablly vibrating i got my eyes checked by the doctor and he said nothings wrong iam attaching a file kindly guide me thru that could it be something serious? Iam not suffering from nystagmus tho is it possible that i could feel my heart beating in my eyes?
