I've tried for a couple of years to get this sorted, but I can't find an optometrist who can understand what I'm trying to say. I got so animated trying to explain it, I got told to "calm down" by the last one, who also gave me another useless prescription, which I spent hundreds of dollars having made into glasses, only to be disappointed. Again. Maybe someone here can help.<p>One of my experiments was to get a pair of actual "computer glasses." If I sit at the perfect distance from the screen, they're fantastic. However, at that distance, even the top and bottom of the screen is enough of a difference that they are fuzzy. Apparently, the so-called "working distance" of the prescription is so narrow that even a couple of inches either way will ruin it. I don't want a laser-focused prescription that only works within an inch. Am I saying that right? Is "working distance" the distance at which the prescription works, or the distance between the near and far usable distance?<p>I want my single-distance prescription _tweaked_ to work _closer_. My current prescription does pretty well from about 2 feet to near infinity. I want the "center" of this workable range brought closer. I want the usable range of the prescription to be "in the room," say, 20 feet at the far end to whatever it works out to at the close end. I expect this will bring my screen into sharp focus, at the expense of, say, driving, where I could use a different pair. I just don't want to have to change glasses when I get up and get a cup of coffee. How can I explain this to an optometrist? Because I've failed about 3 times now, and have $1000 of worthless glasses to show for it.
