Contact lenses are prosthetic lenses used to correct vision disorders and placed on the surface of the cornea. Multifocal contact lenses are designed for presbyopes who would otherwise need separate glasses for near and far vision. These lenses combine multiple focal points with different optical powers to correct both near and distant vision. This allows presbyopic individuals to achieve clear vision at both near and far distances without the need for separate glasses.

Multifocal contact lenses are typically made of soft materials and provide comfortable wear throughout the day. The design of multifocal contact lenses often includes a stronger lens for distance vision in the central area and a stronger lens for near vision in the peripheral area. This allows the eyes to focus on different focal points, providing clear vision at both near and far distances. Thus, users can comfortably focus between different distances without the need to change their lenses or use additional accessories like glasses.
