Hi AS-
I'm not sure how old your husband is, but there comes a time when many could use a little help reading. It has nothing to do with MS, just part of the passage of time :-)
Several years ago it became clear that my arms were no longer long enough to allow me to read. Reading glasses are now required to bring pinted material into focus.

I would start with a regular eye doctor and they will refer him. I had my eyes checked and after having perfect vision needed glasses! I was surprised, but the world is brighter with them :)
