What is one advantage of using progressive lenses over bifocals?

One significant advantage of using progressive lenses is the smoother transitions between different focal areas. Progressive lenses provide a seamless gradient of varying lens powers, allowing the wearer to see clearly at all distances—near, intermediate, and far—without the abrupt change that can be experienced with bifocals. Bifocals typically have a clear line that separates the two prescription areas, which can be visually jarring and require the wearer to adjust their gaze more dramatically when shifting their focus.

In contrast, progressive lenses enable a more natural vision experience, as they facilitate a gradual change in prescription strength. This design helps reduce visual discomfort and the need for significant head movement, making it easier for the wearer to adapt and find their preferred focal point without having to maneuver their head in a specific way to see clearly. This smooth transition is especially beneficial for activities that involve a range of distances, such as reading a computer screen while also needing to look across the room.
