I have progressives. But I also have a special pair of glasses just for use when I'm on a computer, which is many hours a day.
I got the cheapest frames and lens I could find. They are wonderful. My neck used to cramp as I held my head just so to look at the monitor.
I learn a lot on this thread.
I think at present I will use my all purpose short sighted ones for the computer rather than try the varifocal at first and then gradually use them and see how it goes but of course I need to do that within the 30 days.
