Reglazing spectacles

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.

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.

Don't go to high st opticians for this! I do this & have had about 8 or 9 done over the years with excellent results.
I look at other people's specs, find some I like & ask where they got them & often you can find them on eBay.
Once I loved some Whistles glasses & got them on eBay & got them reglazed. I love them & bought another pair from eBay in case these broke. I never use any particular reglazing service but whoever I fancy on the internet, I've never been disappointed. I must have saved thousands.
High st opticians don't offer this service as there's more profit in selling the whole thing.

I go to a very good private optician and have had new lenses put into existing frames several times. They used to say there was a risk of breaking the frames but that doesn’t seen to be a consideration these days. DH broke his frames and they ordered another pair and put the lenses in.

I have varifocal lenses which are medium spec - they are thin but not the thinnest, do have anti-scratch but not anti-glare as I don't tend to drive at night now. When I last visited the optician 6 weeks ago for my 2 year check, the prescription had changed and I asked to have the new lenses put into a previous designer frame that I loved and had bought when I had more spare money as I was working then. To have my old frames reglazed cost me more than having new frames with the new prescription! I bit the bullet, but am seriously thinking of changing opticiansfor another one. I have to say that the major costs of my glasses relates to the lenses. Suggestions, anyone? (I use Boots opticians at the moment.)

My opticians always reglazes my glasses. It was getting ridiculous at one point before my cataract ops. Constant changes in prescription .No longer necessary.
