For many presbyopes, bifocal lenses are a necessity. But it can be difficult to adjust to the harsh line that is found in many bifocal lenses. Fortunately, there are no-line lenses, which are also called progressive lenses. No more lines! Just a change in focusing power which allows you to comfortably focus on any distance. Just as with lined bifocals, distant objects are viewed through the top portion of the lenses, and near objects are viewed through the bottom portion of the lenses.
