Specsavers for me, always like the helpful service I have had over the years, and the choice in quality and price has always met my needs. Not sure about the girl with a pencil though, when I have been they have always measured my frames using what I can only describe as a slide rule/micrometer (LOL) combination, and I have never had a any problem with fit. So when I go back to UK in May I'll be going to Specsavers.
