Did you go to an eye DOCTOR (opthamologist) or an eye TECH (optometrist)?
To me, it sounds like your interior pressure is probably off (but I'm not an opthamologist, there are probably *dozens* of causes). That's not a test they run at an optometry office, but it's one of the very basic tests run at an opthamology office.
If they find nothing wrong with your eyes physically, an opthamologist will send you on to a neurologist 9 times out of 10 (the 10th time is another specialty that they suspect; like an endocrinologist, or ENT... since othersystems can show up in the eyes)
