Thanks ChillD ...seen now..useful.
I go different places but more recently I went to Specksavers and was booked with the "resident" opto at Specsavers and the difference in the quality of service impressed me. Best experience I've had so far & will go back as she is there long-term.
Really well up on aspects others didn't cover, rang me afterwards to give me more information to help me, wrote a list for me on the latest thinking and sent me information (she sourced for me) by post and I haven't bought any glasses yet.
