They had been married ever since they could remember--more than 20 years now. They did not even remember if it was out of love, or was it arranged. They were so young, it was called an infant marriage! It was thaaaat long.
They always viewed things from different perspectives, yet somehow always managed to focus on where their views overlapped.
Wherever one went, the other had to go. They even woke up together. And no doubt, slept together. But, sleeping together never brought any excitement. :( They had grown sick of the other. Totally sick.
You go your way. I'll go mine.
[Angrily, without a thought] As you wish. And don't you dare follow me. Huh!
So for the first time ever, they went their own separate ways and darted in opposite directions. But they felt intensely dizzy (click). They could not stand it, they had to unite. They realized, their fate to stay together was sealed, not by something flimsy as love, but PPRF!

Okay sorry folks for this crap, which I am sure even medicos would find crappy!
It is on simple eyes that mammals possess. Meaning, they always manage to look at the same object of focus, but from different angles. Yet, the brain fuses the two images into one. PPRF is one of centers involved in controlling horizontal eye movements.
Eyes show many types of involuntary and voluntary movements for proper functioning.
Saccades are jerky movements generated mainly in response to changes in visual field (what the brain 'sees'), e.g., a moving target or sudden appearance of something new in the field--a fly falling in your soup! ;) They bring the 'pursued' object just about to the center of visual focus.
Smooth pursuit movements perform the same function as saccades, but are better coordinated, with constant adjustments in direction and velocity of eye movements based on feedback from muscles moving the eyes as well as the images formed by the retinae.
The fast phase of a nystagmus is brain's attempt to keep eyes still with regard to axis of the head when eyes get 'distracted' (the slow phase of nystagmus), say following head movement, saccades or sudden pursuit movements. So nystagmus could be normal, but occurs whenever eyes try to simultaneously look at different things! ;)
