multifocal
Several focus points
Multifocal describes something with multiple focal points or areas of focus.
In optics, multifocal lenses correct vision at different distances—near, intermediate, and far—within a single lens: She switched to multifocal contacts.
In medicine, multifocal conditions affect multiple sites: multifocal pneumonia, multifocal tumors.
The term appears wherever distributed focus matters.
