I use computer glasses and reading glasses all the time when I am spending any significant time at either. Otherwise, it is the progressive lenses. It does make a difference in my neck because my posture is not forced into something uncomfortable for me.
You might at least give a shot at the online source since you can spend less than $15.00 for single vision glasses. Not much to lose. I have a squirrelly prescription and my online single vision glasses work just fine.
