A Multiple Sclerosis Foundation answered. Optic neuritis, a common first sign of multiple sclerosis (MS), can cause blurry vision, blind spots, dimmed color and eye pain. A follow-up study of people with optic neuritis found that the majority of those examined 15 years later had 20/20 vision in the affected eye.
However, the cause of optic neuritis is often unknown. Optic neuritis causes vision loss, which may be mild or severe and may occur in one or both eyes. Loss of vision may increase over 1 or 2 days. Vision in the involved eye or eyes can range from almost normal to complete blindness. Color vision may be particularly affected, but the person may not realize it.
