When I was diagnosed with MS at age 39 I had mild optic neuritis in my left eye. I've always needed glasses since I was kid for near sightedness. Over the past few years my vision has declined in both eyes (even before the MS diagnosis) which sometimes happens as you get older.

When I went on Tysabri my vision seemed to get extremely sharp. The vision in my left eye now seems to be retrogressing a little (like I need new glasses). How do I know if this is from repeat O.N. or just declining eyesight because of age? Can new lenses in your glasses actually help correct O.N.? When I had the O.N. 20 months ago my eyesight seemed more like some one had smeared vaseline over my eye (hazy) rather than out of focus like when you need new glasses.

I'm just trying to figure out if I should contact the neurologist or go to my eye doctor?
