DS (6) wears glasses but we have problems getting glasses to fit him - the frames are often too large / fall down his nose (he is quite petite). In specsavers today and they were trying to get me to choose glasses that I thought were too big for his face - as he will grow into them! Surely I need to get glasses that fit him now for them to work properly? And I assume there is nothing to stop me taking his prescription elsewhere - Specsavers seemed reluctant to give me the NHS voucher that's required.
Really would appreciate some advice
