Peter asked:

I had laser eye surgery in 1995 for short sightedness. Long distance has become blurred e.g. night driving affected. Will naturally occurring long sightedness change this over time I’m 47?

Peter, you have become somewhat myopic (short-sighted) again, either through progression of your condition (can be associated with high amounts of near work, although that story is not straight-forward), or regression of your treatment, or both combined.
At 47, most people will be showing signs of presbyopia, or age-related loss of near vision. Your myopia will mask those symptoms if you are not wearing glasses or contact lens correction, and so in fact is of some benefit to you. Your presbyopia will have minimal effect on your distance vision though, and will not neutralize it. One option is to get one eye retreated to fix the distance and get a blended vision combination, and so see well for far and near. Will depend on your current prescription though.
