I just got had for £757. New frames £243, varifocal lenses £474, and a scan of the eyes £40 which is not covered by the NHS as part of the eye test.Under £250 is cheap.
I'm about to be hit with a £700-750 bill for a pair (varifocals needing a special lens as I'm very short-sighted).
As I posted in another section earlier this week, I think I may try Boots next time. This was with the optician I have used for 20 + years. The old guy who's business it was retired last year and new owners took over, with new prices.
