I finally bit for some moisture chamber prescription glasses and I love them....they do the job too! I am able to tolerate the progressive lenses in them too. I got them from Seefit.net...but they do cost a small fortune, but if you have severe Sicca, from neuropathy or Sjogren's, it is worth it. I can see and I can drive a car with air or heat on! Yay! I got good service too.
