Thanks for this question.
It looks to me like it is possible to get your lens replaced in your old frames- you just have to be insistent! It’s a common question in ‘money saving expert’- apparently companies are often unwilling to do it as ‘the frames are too old’, however, the majority seem to have had success. Specsavers has received good reviews for doing this when asked (however firmly!), as have independent vision shops. There’s a fab article here about just this, and how it could save money and reduce waste too- https://www.theguardian.com/money/2009/oct/04/save-money-glasses-prescription
Hope that helps- and good luck with future lens replacements!!
