What is multi focal lens?

Multifocal lenses are a type of contact lenses or eyeglass lenses that can correct presbyopia, an age-related vision problem that affects the ability to focus on near objects. These lenses incorporate multiple prescriptions to allow for clear vision at different distances, eliminating the need for separate glasses for reading and distance vision.

There are several types of multifocal lenses, including progressive lenses, lens with alternating zones, and concentric circle lenses. Progressive lenses gradually blend the different prescriptions together, while alternating zone lenses have distinct areas for near and distance vision. Concentric circle lenses have rings of varying prescriptions, allowing the eye to adjust for different distances.

Multifocal lenses are beneficial for those who want to avoid constantly switching between reading glasses and distance glasses. It can also be helpful for those who have difficulty adjusting to monovision or bifocal lenses.

While multifocal lenses can take some time to adjust to, many find them to be a convenient and effective solution for presbyopia.
