Most of us do, Ezra. My first glasses were progressives - perfectly useless for shooting sports, as the spot you look through is out of focus- totally. I now have bifocals and they are excellent. I have the division between the reading area and the long distance set higher for work on the computer. At this stage, I have good focus from about 10" to 30" using the lower lense, then from the front sight to infinity with the long distance lense, which is used when aiming, of course. There is no good location for the rear sight, any more.
