Multifocals Lenses

A multifocal lens is a lens that contains two or more prescriptions for correcting vision at different distances. These include bifocals, trifocals, progressives and special occupational lenses. Multifocals are designed to help people see well at various distances, especially as they age. Bifocals (meaning two) are prescribed to aid both near and far vision. Trifocals (meaning three) are prescribed to aid near, arm’s length and far distances. Progressive addition lenses are multifocals with a gradual change in the lens from distance to arm’s length to near without lines in the lenses. As people reach their early to mid-forties, their eyes gradually lose their ability to focus on objects that are close up. As a result, multifocal lenses are often prescribed to adjust to these changes.
