Different Varieties of Multifocal Contact Lenses for Presbyopia Correction

As people age, many notice a decline in their ability to see clearly up close. This gradual change, common in individuals in their mid-40s, is known as presbyopia. To address this, eye specialists often recommend bifocal or multifocal contact lenses. These lenses come in various designs, each suited to different needs. Below are some of the main types of multifocal contact lenses available.

Concentric Multifocal Contact Lenses
These lenses feature alternating zones for near and far vision arranged in concentric circles. The design where the central area aids in viewing distant objects is called a center-distance design, which is widely used.

For individuals who are nearsighted or prefer the central zone to be for near vision, a center-near design is chosen. This is a type of simultaneous vision lens that offers versatility for different visual needs.

Aspheric Multifocal Contact Lenses
Similar to simultaneous vision lenses, aspheric multifocal lenses have a different design approach. Instead of concentric rings, these lenses feature a central zone optimized for distance vision, with gradual changes in power toward the periphery, aiding near vision in the edges.

As you move outward from the center, the lens gradually shifts in power, allowing comfortable peripheral vision for nearby objects.

Segmented Multifocal Contact Lenses
These lenses are structured like traditional bifocal or trifocal glasses, with distinct segments for different distances. The upper part is dedicated to far vision, while the lower part is for near vision, separated by a clear dividing line. Trifocal segmented lenses are also available for more comprehensive correction.
