I actually really miss the old basic NHS frames because of this. Perfectly fine to wear every day, even if you're Michael Caine, and simply not bother with anything more expensive. They were also great for ordering a cheap second pair for manual dirty work, decorating, spare for the car, and to tide you over when the expensive pair inevitably breaks (funny that) etc. A HUGE thanks to Thatcher for removing opticians from proper NHS coverage in the mid 80s. After the demise of NHS frames, even cheap glasses were expensive.

Decades later those NHS 524 frames became all the hipster (and Morrisey) rage. For hundreds a pair. Sometimes using original repolished frames as apparently they were well enough made to last forever.
