I am considering a set of shooting glasses, primary for rifle but I would consider using them for pistol as well.
Why are smaller-diameter lenses sold for rifle, and the larger-diameter ones for pistol? Is this just what people have come to prefer, or is there a reason? Will I be in a bad way if I try to use the same lens diameters for both rifle and pistol?
The smaller lenses in pistol tend to result in people doing too much last split-second adjusting when shooting rapid, dueling or sustained fire. The larger lens helps you mentally accept that you're not perfect and just shoot the shot.
