Prescription glasses with UC
I got prescription glasses last year in February. My eyesight has got worse since then, I can't read writing on the tv even with my glasses on, I have to squint and it's blurry. So at the moment I can barely see. I know with Universal Credit eye tests are usually free every 2 years unless the prescription changes by a certain amount. How much does my prescription need to change to be eligible for a reduced cost on glasses? I have astigmatism so I already need to pay extra to get the anti-glare coating which isn't covered by Universal Credit so if I can get glasses cheaper it would be a massive help. I do get LCWRA and PIP if that's relevant
