For this and other reasons, I had a special set of high-quality glasses, with relatively large lenses, made with prime focus distance set for my nominal distance to the monitor. I can see the whole screen now with minimal distortion and neck strain, no CA.
My usual lenses (the soft kind of bifocals now... I'm getting old ;-) require too much moving my head around to find the proper focus point and distort all over the place in doing so when working on a large computer screen. They were giving me a neck ache as well as a head ache from eye strain. They work great for reading a book and general use, just not for working on photographic images on a large computer screen!
