Eye opens less while reading. Consult?

My eye opens less while reading, writing or Tallying something. I have seen all opthomologist in Delhi. They first said that I have convergence problem thus I did convergence excercise on Synoptophore and the problem of convergence was solved. But, still I cannot open my eyes (Especially left eye) while doing above works. What to do? Who to consult? Also, When I close my eyes tightly though they close (Completely) but my left eye does not close as tightly as right. Is this some kind of nerve or facial weakness. Being suffering from dry eyes and neuropathic pain. Left eye strains on inner corner and opens less. Also, Inner corner of my left eye pains when I have overslept. Also, Excercise strains (Pressure) inner corner of left eye and my vision to go blurr (Previously). Now excercise causes dizziness. Thanks and regard
