Bifocal Lenses

What bifocals are

A bifocal lens includes a distance portion and a near segment, traditionally separated by a visible line. The segment location and size are fitting decisions based on posture and tasks.

Who considers them

Adults with presbyopia who want predictable near zones, people who disliked progressive swim, or those with occupational needs that match bifocal geometry. Some prescriptions historically used lined multifocals for other clinical reasons—your clinician explains your case.

Adaptation and optics

You learn to drop your gaze into the segment for near and look ahead for distance. Intermediate gaps (dashboard/computer) can feel underserved compared with occupational progressives—an honest tradeoff, not a personal failure.
