sleepy eyes

Figures. I hate when something is wrong, but when you get it checked out at the doctor they say, "nothing is wrong." grr. My teary-eyed condition is neither dry eye nor an infection of any kind. The opthamologist suggested it may be allergies, but since when does someone have burning/itchy/excessive teary eyes during all four seasons?
she gave me some eye drop sample to see if they help. boo.
