Progressive lenses are a type of multifocal eyewear designed to address presbyopia, a condition that typically develops with age and affects the ability to focus on close-up objects. Unlike traditional bifocals or trifocals, progressive lenses provide a seamless transition between multiple prescriptions within a single lens. They have no visible lines, offering a more natural visual experience.
The lens is divided into different zones, each designed for a specific distance. The top portion of the lens is for distance vision, the middle for intermediate vision (such as computer work), and the bottom for near vision, such as reading. This smooth gradient allows wearers to shift focus without the abrupt changes found in older styles of multifocal lenses, resulting in a more comfortable and aesthetically pleasing solution for people experiencing presbyopia.
