Im going blind please help?

So about a year ago, everything started to go blurry in my right eye. I have had every test in the book. EVERY eye exam that they could possibly do. My eye is not correctable with lenses. I have had 2 MRI's, I have seen 2 different neurologists, i have had an eye exam where they could actually see the inside of my eye layer by layer. My vision in that eye is continuously decreasing and im scared... today i noticed that in my right eye i cant see long distance but i could see up close really well! and then i noticed by covering up my right eye, that looking through my left eye i Cant see very well up close but i can see long distance!!! why are my eyes doing the same thing except in reversal!? Has anyone ever had this before? Does anyone know what could be causing it?? I am worried that i will go completely blind someday...
