I stopped driving last year after my optician told me I was no longer safe on the road. Like you I thought I was okay to drive. After cataract surgery and some laser treatment I realise how bad my eyes were. Eyesight deteriorates so slowly, I was not fully aware of the true state of my eyes.
I am allowed to drive again now but I no longer want to. I have adapted and, at 75, I probably shouldn’t be driving for too much longer. I am lucky with bus routes, local shops, GP and family nearby, and I know your circumstances are probably different.
But really? You have been told by a professional not to drive but you are determined to carry on anyway? Put your pride away and consider the possible consequences of that choice.
