lately more and more I'm noticing that my eyes feel like they all of a sudden "unfocus".

Reading a book or something I have to close one eye....and driving is a nightmare.

Is that kind of what ON is?

I'm undiagnosed except for problems with my peripheral nerves...

Curiousforever,

I also undiagnosed,but suffer from unfocused vision.I had a vision test in January and the vision had dramatically changed in a year.Especially my up close vision.My glasses are no longer strong enough to read.I have an appointment with the eye Dr. today.
I am waiting for the results of the vep test I done on Tuesday.
My vision worsens with heat.

Curiousforever,
Had eye appointment today.My up close vision went from 20/25 with glasses on to 20/175 in right eye and 20/20 to 20/50 in left eye in just 3 months.Optomitrist didn't look for ON,since I had the VEP on tuesday.He's going to wait on those results.He stated that the deteriorating vision is not normal and he beleives that the elevation of the myelin basic protein(in the spinal fluid) has a lot to do with it.Plus the lesion in the occipital region.I won't get my new glasses for 2 months,he said it will take 6 weeks to fight with insurance company to pay for them.

Same happened to me - decreased vision in R eye only in just 3 months. My lesions are also in my occipital lobe.
