What does multifocal reading glasses mean? What is the difference between reading glasses and traditional reading glasses?

People who wear reading glasses need different glasses to see the distance, or they don't need glasses to see the distance. And you can't see the distance clearly by looking at the nearby glasses. Very inconvenient.

Multi-focus reading glasses, the middle and upper parts are far apart. And the bottom is to look closely. I have it myself, but I really can't. It makes me dizzy.
