Progressive eyeglass lenses
The correction for near vision in the lower part of the lens decreases progressively toward the upper edge of the lens, providing visual acuity for longer distances in the upper part of the lens. The most effective progressive lenses at room distances are so-called multifocal lenses for office use/amplified reading glasses. In these lenses, the typically narrow field of vision for progressives can be made wider by omitting the area for long distances in the upper part of the lens. At the same time, the change in lens power decreases, making it easier to see different objects.
