Progressivgläser

Progressivgläser, also known as progressive lenses or multifocal lenses, are a type of eyeglass lens that corrects presbyopia, a common age-related condition where the eye's natural lens loses its flexibility, making it difficult to focus on near objects. Unlike bifocal or trifocal lenses, progressivgläser do not have visible lines separating the different prescription zones. Instead, they offer a smooth, gradual transition from the distance prescription at the top of the lens to the reading prescription at the bottom.

The design of progressivgläser incorporates three distinct zones for vision correction: distance, intermediate, and near. The upper part of the lens provides clear vision for far-away objects, such as driving or watching television. The middle section of the lens offers a correction for intermediate distances, useful for tasks like computer work or looking at a dashboard. The lower part of the lens is designed for close-up vision, allowing for clear reading of books, menus, or smartphones. The power of the lens changes progressively downwards, providing a seamless visual experience across all ranges.

The adaptation period to progressivgläser can vary from person to person. Some individuals adjust quickly, while others may require a few days or weeks to become accustomed to the different zones. It is important to move your head rather than just your eyes when changing focus between distances. Modern progressivgläser are available in a wide range of designs and materials, offering improved visual comfort and aesthetics.
