Good replies 👏👏
My own research from earlier posts indicates,
The DVLA pays for an eyesight test that it officially requires you to take with their contracted optician,
Specsavers. You should not be charged for this test irrespective of your age!
Yes, if you need prescription lenses to meet the legal eyesight standards for driving in the UK, it is a condition of your motor insurance policy that you wear them while driving. Driving without them makes your insurance invalid, and any claim would likely be refused.
Last summer my Posterior vestibular detachment was scary in North Wales. The A&E at Porthmadog don’t do eyes . They sent me within the hour to the Specsavers Ophthalmologist in Porthmadog. He had all the kit and reassured me the issue was not serious and would heal,. However as we were on holiday he referred me to the Bangor Eye hospital for a double check two days later. Great service. And the Specsavers chap was mid 30 s and knew his eyeballs😉
