My sister got a special kind of lenses the last time that she purchased 
prescription glasses.  They have a coating on them that is designed to 
reduce glare from CRT's.  They are actually some kind of plastic lenses, as
well.  I think that she had had symptoms of dryness before getting the new
glasses, but they have disappeared with the glasses.  Unfortunately, the 
lenses were more expensive, of course.
