Multiple sclerosis and my eye sight, is there a relation between the two?

Yes!: I'm assuming there is a problem with your eyesight? If so, then yes optic neuritis can affect the vision and is associated with multiple sclerosis. The nerve sheaths around the nerves get affected and this can cause decreased vision, pain with eye movement , and/or double vision.

You bet: MS commonly affects the eyes, and if you have loss of vision, double vision, any abnormal eye movements, it is possible that MS is the cause. But other eye events can co-exist, so see an ophthalmologist to get this pinned down. Hope you are taking a potent MS disease modifying agent, as this can protect your eyes.
