Bifocal vs. Multifocal — What's the Difference?

By Tayyaba Rehman — Published on October 16, 2023
Bifocals are glasses with two distinct optical powers to assist with clear vision at both near and far distances. Multifocals are glasses that incorporate multiple optical powers to provide vision correction at various distances.

Difference Between Bifocal and Multifocal

Key Differences

Bifocal lenses are distinguished by having two distinct areas, each tailored for different viewing distances: one for near vision and another for far. On the flip side, multifocal lenses feature more than two prescription areas, crafted to provide clarity across multiple viewing distances, thereby aiding in seeing at near, intermediate, and far distances seamlessly.

The bifocal lenses often are adopted by individuals who primarily require clear vision for reading and distance, providing a straightforward, two-zone solution. Conversely, multifocal lenses are often the choice for those requiring corrections at various distances, offering a more comprehensive, albeit sometimes pricier, visual solution.

When considering outdoor activities, bifocal sunglasses are available and are commonly used to assist with near and distance vision while outdoors. Multifocal sunglasses, offering corrections for all distances, are also available, providing a versatile, all-encompassing optic solution for an active, varied lifestyle outdoors.

For those who require correction for near and far vision, bifocals offer a simpler, typically less expensive solution that effectively addresses these two specific needs. Multifocal lenses cater to a wider array of visual needs but can be complex and may require a period of adjustment for the wearers due to the multiple viewing zones incorporated in them.

Visibly, bifocal lenses traditionally exhibit a noticeable line or segment that separates the two lens powers, allowing wearers to switch their focus between two distinct viewing fields. Whereas multifocal lenses, especially progressive ones, lack these visible lines and offer a more gradual transition between the various prescription areas, providing a smoother visual experience from near to far.
