If you have a Costco card I'd highly recommend using their opticians, I was with them for years and they were great but I stupidly used Specsavers last time as had a voucher through work and the experience was shite, getting passed from one person to another before ending up with a pair of glasses I don't like as I felt rushed/pressured when I picked them, needless to say I'm going back to Costco for my next pair.
