Found some glasses today in a fairly random place in the Lakes (Took a grid ref - 354298). Near The Tongue, close to Bannerdale Crags (Mungrisdale). They are blue prescription glasses from Specsavers in a black DKNY case. On the glasses is written "54 14 -140 Frida 25664751". Let me know if they're yours and I'll send them your way...
