Multifocal lenses are specialized eyeglass lenses designed to correct vision at multiple distances. They typically combine three different prescriptions: one for seeing far away, one for intermediate distances, and one for close-up tasks like reading. This allows wearers to see clearly without needing to switch between different pairs of glasses. These lenses are often used by people experiencing presbyopia, a common age-related condition that affects near vision. Multifocal lenses come in various styles, including bifocals and progressive lenses, each offering different visual experiences and benefits based on individual needs and preferences.
