Learn about Bifocal & Multifocal Lenses

As you approach the age of 40, your eyes’ ability to change focus between near and far objects begins to deteriorate. Eye doctors attribute this natural phenomenon, Presbyopia, to the weakening of the eye muscles. Eventually, most people seek an optical solution to help their eyes adjust from far to near objects and for reading. A single prescription lens usually solves the problem, unless the eye also needs distance vision correction. In this case, multiple prescription lenses are required.

Bifocal Lenses

Historically, bifocal lenses have been the primary solution for Presbyopia. A bifocal lens is a combination of two different prescription lenses that have been cut and assembled into one lens: the top two thirds for far vision and the bottom third for near vision. The two halves are separated by an unsightly line. Although today most bifocals hide the line well, there are other disadvantages to these lenses. Some bifocal users may experience headaches or dizziness. The sudden “jump” from one prescription to the other is uncomfortable and can cause eye phatic.

Multifocal Lenses
Multifocal progressive lenses are the ultimate solution for Presbyopia. Through advanced technology, multifocal progressive lenses combine several prescriptions into one lens and provide a subtle “optical path” that supports the eye’s gradual transition between the different zones. Multifocal progressive lenses eliminate head adjustments and most headaches. Esthetically, multifocal progressive lenses are preferred to bifocals since there is no line through the middle of the lens.

Available but costly, multifocal progressive lens technology has been reserved primarily for affluent consumers, with no economical solution for most people. To solve this problem, the founders of EyewearHub.com worked directly with optical lens manufacturers to create a private label multifocal lens for a fraction of the cost. EyewearHub.com’s multifocal lenses use only the latest technology and come with anti-reflex, anti-scratch, and UV protection coatings.
