I’m 73, have the start of cataracts which affect my sight in bright light. I ride a motorcycle with far too much power at silly speeds in the south of France generally in the morning before it gets too hot. The loss of vision from bright sunlight to shade is incredible. To counteract the brief periods of semi blindness I look at the road surface ..important as a diesel spillage is game over.
Evening paragliding is more difficult and I sacrifice looking at my instruments with corrected dark Polaroid glasses and avoid situations where conflicting traffic is up sun. (Often by landing and waiting until others have as well).
My wife hasn’t driven for decades at night as women have more cones than rods..the former are for colour perception whilst the latter work in low light.
‘It’s about understanding your limits like look out at junctions wrt cyclists and the width of the windscreen pillars.
