NF2 - Red Eye and double image after surgery

[PBFight4SB]

Had third surgery on same side, this time little invasive, with the hope to remove complete tumor. While surgeon seems to have done good job in retaining facial nerve, swallow intact, the eye on the side of the surgery becomes red sometimes. this may be because of spending too much time on Phone and Tablet but sometimes due to exercise too.

The further complications now is that there is blurry / double image vision wherein the eye has to be closed to view something.

Is this a common problem? Will we need to visit Eye Doctor? Surgeon seems to not care much about this.
