I'm not set in my ways, but I qualify for the old part. My eyesight has gone downhill since I hit 40 (now 61). If I use my glasses I can see my sights but not the target, if I don't use my glasses I can see the target but not my sights so the green-red dot sights fix my problem. If it was a case where it was a defensive type situation it would be more of a point-and-shoot situation. Sights are not really required.
