I had an eye test yesterday. It was only a year since my last test. Last year I needed a new prescription and trialed contact lenses. This failed because of dry eyes. Anyway, now I really need new glasses and needed to check that my eyesight hadn't changed in a year before I fork out loads of cash! My optician said that my sight had changed 'quite significantly' in the last year, mainly due to worsening astigmatism. To the extent that I now need a separate pair of reading glasses. Is it just a co-incidence that I've had worsening hypo symptoms in the last 6 months?
