I wear yellow glasses over my specs, the same ones I wear when driving into the sun. Most older people will have difficulty at night in unlit roads. Adaptation reduces with age eg we cannot see so quickly when coming in from bright sun . It is a natural aging process. So drive in a lower gear, so that you feel that you have more control, use main beam if in the front and no vehicle is coming. Stay aware of where the side of the road is and remain focused on the centre line if car headlights are coming towards you
I have decided to only travel short familiar routes at night, there are always those inconsiderates on the road coming towards us who drive too fast and who don`t bother dipping main beam. 25 minutes last night in damp mucky conditions was enough for me. The whole road is 40/30 mph and too narrow for overtaking, which helps
I wear spectacles, have done for 52 years and see an optician regularly. We need to be aware of driving limitations and safety
