ok all, I need your wisdom

Chris went to the opthamologist today for an eye exam (of course I couldn't go because I couldn't take off work) so my parents took him.

He said his right eye had severe nerve damage due to his MS and that glasses won't help. Not being there I couldn't ask questions. He did tell my parents that it could be better but you never know and wants to see him in three months. He did not say ON but is that what this is?

Chris would barely read the second line with his right eye.
