This would also be the consequence of having cataract surgery that gives you perfect distance vision at the cost of your close-up vision. I'm nearsighted and have worn glasses since I was about 10, so wearing glasses is no big deal for me. I'm now wearing progressive lenses; yes, they take some getting used to at first, and you have to be careful on stairs, but on it's well worth the convenience. I put them on in the morning and take them off when I go to bed - no worrying about where I left those damned reading glasses. When I got cataract surgery, I told the doctor to leave my nearsighted vision the way it is and let the glasses handle it. I can focus on computer screens well enough, and when I'm driving the shift from the instrument panel to distance and back has become automatic. If I want to look at something really close (like my wife's eyes), I take off my glasses, or look over them. Your mileage may vary. I did once get a pair of single-focus glasses made that focused at the distance of a computer screen (or music stand). Just after I picked them up, my eyes changed, and the glasses then focused at 8 feet.
