Welcome from another ex Bank Manager but still working (not in a Bank thank goodness) to pay for my driving hobby.
Unfortunately with advancing age night driving will become more difficult and there is nothing much we can do about it. With age the eyes become less able to distinguish shades of grey, at least that is what I'm told. Also retinopathy causing narrowing vision can become an issue and almost inevitable if diabetic. Then there are cataract problems to expect if we live long enough.
Trouble is I have all these problems. Don't worry though if I ever get to drive you I've been driving with my eyes closed for years now.
Enough of this gloom, welcome and do try and make it to some of the ADUK driving days.
