What Causes Feeling Of Passing Out And Persistent Problems With Eye Sight?

I have had constant continual problems with my eye sight. everything is distorted everyday and when I speak with people face to face I start to get very warm and feel like im going to pass out. I have been tested for epilepsy, brain tumors and have had an ear test done. I was prescribed glasses after a eye exam as well. the ear exam came back showing some abnormal signs but the hospital had no idea where to send me after??? any suggestions of my next move. they sypmtoms have gone on 6 years now with no hope...please offer any suggestions you may have.
