Got my new Autograph SV lenses the other day (my Rx is roughly -5.00 OU) and WOW are these things sharp! The vision is crystal clear, literally like wearing contact lenses, and there is much less peripheral distortion than my other pairs (same Rx, all 1.67 with AR). I wasn't too sure how much difference this would make on my SV Rx, but I'm truly impressed!
