It somewhat depends on weather you are near sighted or far sighted & if you have been wearing bifocal lenses already. Anyone who can take their glasses off and see better close up is near sighted. That is the opposite of me. I can see at a distance without glasses but not clearly. Up close, I can't read the Farmall on the side of my H tractor.

I have worn trifocals for over thirty years now. Started out with bifocals and graduated to tri focals. All hard line style.

I got the brilliant idea about twenty years ago that progressive would work better. I thought, then I can just raise or lower my head slightly and get the perfect focus at those close ranges. What I found out right away was that the progressive change is also horizontal as well as vertical. In other words, I had to move my head side to side to maintain focus even when reading a line in a book. So, with side to side, up and down it was just more difficult. The actual focal spot was just too small. This of course varies with how strong the correction you need. Mine are on the higher end of strength. I gave up and got my older hard line tri foculs style back. I had a deal with the optometrist, because the progressive cost more, they would not charge me anything if I wanted to go back to hard lines.

They had warned me that it is difficult for someone to change to progressive if they are accustomed to hard lines.

Wife has progressive, only a slight correction in hers but I still see her moving her head trying for that sweet spot. Her problem is double vision and has the full five prizms in each lens. It still does not correct it except at specific distances. Needless to say, she does not drive anymore. (Maybe down to the other end of the farm to pick me up when I am pheasant hunting, closing one eye).
