I could never make my eye focus on the front sight in a hurry. If I strained for a little while, and closed the other eye, I would be able to force it. After I hit 50 years of age, even that much became impossible. Pistol optics solves that problem. Not sure how old people dealt with it throughout the 20th century. Perhaps they just missed a lot, or didn't live long.
