+0.50 over the distance (add cut by the same) is sweet in a small room, primarily for the more advanced presbyopes. The cut add also reduces unwanted astigmatism, and of course Zeiss designs a nice PAL with a wide distance zone.
They might even double as computer/task eyeglasses for some folks (screen carefully) and select nursing home residents.
It used to be called Gradal RD (room distance) decades ago.
