Double Vision

I've had bouts of double vision over the years with my MS. It was the initial sign. But this time it's lasting much longer, and is quite bothersome. I've had it now for almost 5 months.

Strange thing is that it improves at night. As soon it is dark outside, I see everything in single vision for the last week, yet when I wake up in the morning, everything is double again.

Is there any logical explanation for this ?

Interesting...  I'm hypothesizing here.  The eye uses different receptors in the retina in daylight and in darkness.  Perhaps the brain is better able to reconcile the image into one single image in the dark.  Generally you use more distant vision and have less detail at night.

Another possiblility is that at night the brain "ignores" the vision from one eye and you only perceive what is being seen by the other eye.  This could happen if the night vision from one eye is much worse than there other, or if in, low light one of your eyes doesn't track properly and wanders.

The phenomenon of the brain ignoring the visual input of one eye is well established.  In kids with "lazy eye", one of the eyes wanders and doesn't track with the other.  The brain really doesn't like to process two different images, so it shuts out the input from the lazy eye, and the brain only perceives the image from what the child is actually looking at.

In double vision the images are just a little off.  The brain can't reconcile them and you see double, which will cause rapid and severe mental fatigue, I bet.

Just a theory.  Sorry I really don't know the correct answer.  I'm sorry for your difficulty.  Loss of usable vision is incredibly hard to deal with.  My husband of 23 years was totally blind.  He went through a lot.   I hope this passes and stays away.  I haven't had visual symptoms..(yet) Quix
