I feel so silly not knowing this by now... I have a -18.5 and a -17.5 prescription and an astigmatism. Bloody eyes still haven't calmed down and tend to change every couple of years, so I'm buying new lenses pretty frequently. The last time I got new lenses in my frames, around two years ago, I vaguely remember getting a voucher for around £5 off my lenses. Obviously factoring in that I needed the lenses thinned down, it cost me around £230 I think!
I've looked at the NHS website, and for some reason I'm really struggling to understand if I'm entitled to any help towards paying for them! Can anyone help?
