I am the opposite. I need glasses to read and work up close. For distance I see as well as I did when I was 20. My bifocals are for reading and working. The tops are clear since I do not need help seeing at distance. My wife asked my why I did not just use a pair of cheap reading glasses. Unfortunately, I work as a bench jeweler. With Bifocals I do not have to take my glasses on and off when working. With reading glasses I would have to remove them every time I needed to find burs or other tools on my bench.
