As I wrote above, it's not just about the eyesight, but that a rifle scope allows shots under conditions that are not possible with open sights. We don't need to talk about shooting at longer range, but a rifle scope is also of great help when there are poor light or visibility conditions. At night you need a scope in all cases, but even in dense bushes or forests a shot can be placed much better with that than with open sights. With a scope you can focus through the dense vegetation than looking at a green wall through the open sights. This is my personal experience, especially when it comes to buffalo hunting. I could not have shot under good conditions two thirds of my buffalos with open sights.

As far as hunting at night is concerned, we often do that in Europe when we hunt wild boars, but in Africa it can also happen under special conditions. I shot an elephant, a crop raider in the middle of the night, and something like that was only possible with an optic. That was the first thing the PH asked me, if I had with me a rifle with a scope.
