Let's say we are -2.00 and buy a pair of glasses -1.00.
Based in this our natural focus point is 50cm. By using the glasses, our focus point change to 1 meter.
It's clear to me that we would have optimal vision now from 1 meter and less compared to before at 50 cm or less.
But what happens to objects more far away of our new focus point? Le's say 2 meters. Would we get a partial visual clearity improvement with this undercorrected glasses?
