If you are wearing your myopic correction to read, I can think of only two 
reasons.  The first reason is that you have become more myopic, in which 
case your comfortable reading distance exceeds your punctum remotum, or 
natural focal plane.  You can test this out by bringing the reading 
material closer, without wearing the spectacles of course.  It should 
become clearer.  If this is the case, then reading with your myopic 
correction should be leaving you slightly myopic, i.e. just enough for 
comfortable reading.

The other scenario has to do with binocular vision and the presence of a 
high exophoria or convergence insufficiency when your eyeglasses are not 
being worn.  This can create eyestrain, headaches, occasional double 
vision, etc.  When the myopia is corrected, normal accommodation takes 
place which acts to reduce the convergence problem, making the eyes work 
together.  Covering one eye can also help as it eliminates the stress of 
binocularity.  This situation could also be aggravated by the MS, as it is 
a neuromuscular problem that is made worse by fatigue.
