Can anyone tell me if my eyes are going bad?

for about the past 5 months I have been experiencing double vision, blurred vision (I see things in a 3-D sort of way) and this happens most of the time upon standing and my head feels as though there is a lot of pressure in it for a few minutes while the pressure extends down through my arms and fingers and eventully goes away.  My left eye feels like it is really open and my other eye feels like it wants to close, but when I look in the mirror they are both the same size and so are my pupils.  It's a weird feeling and none of my other colleagues can think of what it coud be either.

I have spoken with my dr. and had blood work drawn up and nothing seems to tell them I have any condition, my BP is fine, labs normal.  I thought it might be orthostatic hypotension, but that was ruled out.  Can anyone tell me what this may be.  

I was, also, told a coupel of days ago that my left eye had an intraoccular pressure reading of 22 (which isn't too bad) while by left eye was a 19, and normal.  

Help.  I am tired of this feeling and I am starting my new career soon.
