i forgot to add on, in night time, my right eye vision starts to become normal. i don't see any more halos.
Sometimes people notice visual details more when the other eye is definitely having a visual problem. It could be normal.
I would test your vision in regular daylight conditions. If it is OK, just ask your doctor when you have a follow-up for your optic neuritis. Otherwise, try to get in within a week to find out what is going on.
