My Father put a red dot on one of his pistols earlier this year. He was having the same issue you guys describe, older eyes having trouble maintaining a focus on sights and target. We purchased an optic with the hope it would fix that issue for him, and it did just that. Now I have to really work to keep up with him, the Deltapoint optic is almost like cheating, place the top of the triangle on your target and give it a squeeze. I do see where it would be hard to quickly acquire the dot within the sight from the draw, I usually have to play with the angle I hold the gun to find the dot before I can start firing, with practice it will get faster I'm sure.
