I have this at times, but attribute it to the fact that the eye is off and on dry, is getting drops and gels put in it, and has also somewhat been affected by the damage to my Trigeminal nerve during surgery (facial sensations). The sensation in that eye is 'different' on the outside section of the eyeball. Can't really explain it, but it's almost as if it's not feeling completely right. As such, when I get blury vision in my AN side eye, I chalk it up to the number of things going on on that side. In fact, I'm due to have my eyes checked (coincidence on timing) but just cancelled the appt. b/c I don't feel it would be an accurate portrayal of what my vision will be like (I'm just assuming it's affected somewhat from surgery and will 'regulate' in the coming weeks/months).
Not sure exactly why, but I think I'm in the same boat.......
