Reglazing spectacles

Spec savers will put a new prescription in older frames problem is for me my frames are low cost but my prescription lens is expensive with thinning, coating andreactalite added. So there is no point.

This sounds like your optician is wanting to make money above providing quality eye care at an affordable price.
I wear spectacles constantly so replacing lenses isn’t an option but my optician will put new prescription lenses in one of my previous frames if possible ie there’s no damage to the frame. And actually, the optician normally sends everything away to a specialist laboratory anyway.
