Dim or blurred vision

BMJ Group Medical Reference

Your multiple sclerosis (MS) can give you vision problems if it causes inflammation of the main nerves to your eyes. Doctors call this optic neuritis. [3]

  • Things might look blurry for you from time to time.

  • Or things might look dim even though it's light around you.

  • Your vision might get worse over several hours or days.

  • Usually just one eye is affected.

  • The area around your eye might hurt, especially when you move your eye.

Vision symptoms are often the first clue that you could have MS. They can come and go throughout the disease, but tend to happen in the early stages. The good news is that your vision will probably go back to normal.

Some people with MS get double vision, or move their eyes quickly from side to side without meaning to. (This is called nystagmus.)



Inflammation is when your skin or some other part of your body becomes red, swollen, hot, and sore. Inflammation happens because your body is trying to protect you from germs, from something that's in your body and could harm you (like a splinter) or from things that cause allergies (these things are called allergens). Inflammation is one of the ways in which your body heals an infection or an injury.
