After waiting 3 months for the DVLA to “process” my licence renewal, they decided I neede a field vision test-why they didn’t ask for this when they wanted an eye test 4 months ago beats me! Anyway, for anyone who has to go through the same thing, it is worth remembering to book an early appointment before your eyes get too tired. You also need to ask for more than one test, perhaps with and without glasses on. My test with glasses showed a perfect horizontal line of weakness. It was the top bar of my spectacles blocking my vision. Anyway, it wasn’t too bad at all and the optometrist was very much on my side.
Best wishes everyone.
