Specsavers - The end of a long relationship!

I've been a customer of Specsavers in Leicester for a good many years, and both my kids and my wife have been their customers. Their prices have always seemed fair, their staff knowledgable, and the shop clean and comfortable. There's never seemed to be the pressure to spend 'just a little bit more' that I've heard of from customers of other chains.
So, what's gone wrong?

Last July I replaced my ageing varifocals with a new pair, as you do! I've recently noticed that in some light conditions they look as though they are dirty, and when held at an angle the lenses look crazed - or at least the coating on the lens looks crazed.
These lenses had the same non-scratch surafce that my previous pair had, which served me well for, what must be, four years, and they never looked like the new ones.

So I took them back to Specsavers for them to have a look. It seems that I've either been heating them up to very high temperatures or mistreating them. The treatment they had was no different to the old pair that lasted five times as long.

I was particularly upset at the offhand way I was dismissed as a serial spectacle abuser! I was not looking for a refund, but an offer to look properly at how the non-scratch coating had broken down might have been more re-assuring - or a small discount on a replacement pair.

I have heard good things about the Opticians at the local Tesco.
