Progressive lenses are line-free multifocals that have a seamless progression of added magnifying power for intermediate and near vision.
Progressive lenses sometimes are called “no-line bifocals” because they don’t have this visible bifocal line. But progressive lenses have a significantly more advanced multifocal design than bifocals or trifocals.
Premium progressive lenses (such as Varilux lenses) usually provide the best comfort and performance, but there are many other brands as well. Your eye care professional can discuss with you the features and benefits of the latest progressive lenses and help you find the best lenses for your specific needs.
