MS Symptoms: Vision Problems More than half of people with MS experience a vision problem called optic neuritis. This inflammation of the optic nerve may cause blurred vision, loss of color vision, eye pain, or blindness, usually in one eye. The problem is usually temporary and tends to improve within a few weeks. In many cases, vision problems are the first sign of MS.
