Ophthalmologist

I ask this because before I was diagnosed with MS, I went to the eye doctor, & he gave me what he said are 'light' reading glasses. So later, I get diagnosed with vitamin D deficiency (living in Minnesota at the time.) After being on the 50,000 IU of D3 a week, for 8 weeks I think it was, my vision was magically corrected and I cannot see out of those 'light prescription' reading glasses ever since. Right now at work I carry around a pocket magnifying glass for the times I just can't bring things into focus.

Optho! They can see if your vision has changed, too. I have a history of Optic Neuritis, and so they watch it every year. That's progressive, too, but I like ophthalmology way more than optometry!
