Well, even if I'd stayed with the old one, I'd have changed because the place has been taken over by Scriveners and I didn't know anyone there. I had my eye test - change of prescription - and started to look at frames, and there was absolutely nothing I wanted. Not for fashion reasons, but because, as a bifocal wearer, I need a deep lens and the stupid modern fashion is for very narrow ones.
After the eye test I went round the corner to another optician (a local family firm) and they had a big stock of old frames which take deep lenses. I went back to the first shop, got my prescription and £62.70 voucher (tax credits) and have ordered a set of varifocals with nice moony gold-plated frames, which he sold at a discount because they are old stock. They will have a water-repellant, anti-glare, anti-scratch coating and will turn grey in sunlight.
