Dr James Sheedy, did a study of 28 progressives on the market, trying to determine which is best overall. This was a very scientific study. The abstract on MEDLINE is here
http://www.ncbi.nlm.nih.gov/entrez/q...tool=iconabstrI have been unable to find a link to the actual report. It was published in Optometry Feb 2004 Vol 75/issue 2. I received my copy at a Younger seminar (their lens ranked in top 5) Shamir Genesis ranked 1 and 2 in nearly every catagory. I will continue to look for a link or if someone knows where a copy is stored post. This is a wonderful study that tries to answer we are all asking...which progressive is best.
