I needed to have both eyes done several years ago. I selected the option for computer monitor vision without glasses, since I had been wearing glasses for distance vision (and cycling) for decades. I was expecting to need glasses for both distance and reading. What I got was much better than expected. I can see better now than when I was 18. Computer monitor vision is excellent, I can ready anything better than low quality 6 point print, and I can see well enough to drive without glasses, although I do wear them for distance vision. Reading glasses are only needed for fine close up work.
