OK, the bad bit first: yes, you can go blind through MS - but a Sssue says, this is rare and even then it is usually temporary.
You do not say what the “visual disturbances” are, but you need to know that there are two optic nerves (you have two eyes after all), and they divide on their way to the brain.
The inner side of each eye (nearest your nose) crosses over and feeds the visual image to the opposite side of your brain.
Those bits of the brain then feed back to the visual cortex, where all the visual images are fused into one percept of what you are looking at.
So, even if one eye, and its nerves fail you, you can still see quite well. You can lose depth perception close up (the experts don’t agree on how close) but probably less than 50 feet, and I have known more than one person with only one eye who was still driving. I travelled with one such on a 100 mile run across Germany, and even knowing that he only had one eye, you could not tell any difference - he had learned what to do to compensate.
If your disturbances are the two eyes “fighting” each other, a good opthalmologist will soon sort out which one is the problem, and a patch over that eye will smooth things out until your brain gets to rely on the good eye.
Fear not - all is not lost!
