A specific category of multifocal lenses designed to provide clear vision at varying distances near, intermediate, and far without visible lines. This lens type allows wearers to see seamlessly across a spectrum of distances, correcting for presbyopia, the age-related loss of accommodation. As an example, individuals using this lens type can read a book, view a computer screen, and observe objects in the distance without needing to switch between different pairs of glasses.
These lenses offer a significant improvement in visual comfort and convenience compared to traditional bifocals or trifocals. The absence of distinct lines improves the aesthetic appearance of the eyewear and eliminates the image jump experienced with lined multifocal lenses. Historically, the development of these lenses marked a turning point in vision correction, providing a more natural and visually appealing solution for individuals with presbyopia. Their adoption reflects a growing demand for optical solutions that prioritize both visual performance and cosmetic considerations.
