I have done business at 20/20 for several years now and have been very happy with the results.  Last month we had a problem with my new glasses and I could not get used to the lenses.  I went in for a follow-up, and it was decided that the lenses ordered were not correct.   A new eye exam was done and new lenses were ordered at no cost to me, and I received an apology from the eye Doc.  I was 'armed for bear' when I went in but left happy.  I will continue to use them.
