Never been more angry. I do have early corneal dystrophy and explained my eyes get very dry. I asked if my prescription had changed much and the optician said that she couldn't see my previous prescription in the examining room and marched me out to the reception for new glasses. I explained that the last 3 eye tests (over 9 months as optician said 3monthly tests) were all different and he said quote... you could have another test in 20 minutes and it would be different by 0.25. IT'S JUST NUMBERS!!!!! I explained that my glasses were 7 months old and I couldn't afford to change them twice a year. He must have taken me for a complete fool if he thought I believed eyesight changes every 20 minutes. Absolutely furious. Shall not be returning.
