I feel for you. I've had ON in both eyes many times over the past years, but never both eyes at once thank goodness.

Mine always starts with severe eye pain, but doen't always proceed to blurry vision. I've not noticed any differences with colour vision during my flares either, but the ON has always been validated by a Neuro or an Opthalmo.

Sometimes I think that every single MSer has a different strain of the condition. We're all so very different!
