Progressive lenses are a type of multifocal lens that seamlessly integrates the prescription for distance, intermediate (e.g., computer screens), and near (e.g., reading) vision into a single lens. The upper part of the lens provides distance vision, the lower part for near vision, and the middle part transitions the prescription, eliminating the dividing line found in traditional bifocal lenses. This solves the problem for middle-aged people with presbyopia who often need to frequently change their glasses to see objects at different distances, providing clear and comfortable vision while maintaining the same aesthetic appeal as regular single-vision lenses.
