I MUCH prefer the Seiko 1.67 (although I'm wearing a pair of Seiko's 1.74's now (I know my Rx doesn NEED it, but I wanted to try them)). I wore poly for years until I got into the optical industry. Sadly that was with Lenscrafters in the early '90's, so my choices were Poly or Spectralite. I choose the latter and have never worn Poly since (except my saftey glasses). Maybe I'm more sensative to Poly than most, but I see much better out of the 1.67's. I honestly don't know what the ABBE's are on any of the lenses; I know what I see better out of.
