What is a common feature of monovision design lenses?

Monovision design lenses are specifically created to address different visual needs by having different focal points in each eye. This approach is particularly popular among presbyopic patients, who require both distance and near vision correction as they age.

The key feature of monovision design lenses is that one lens is optimized for distance vision, typically placed in one eye, while the other lens is adjusted for near vision. This setup allows the wearer to see clearly at both distances without the discomfort caused by multifocal lenses, which can create a zone of confusion in the transition between distances. As a result, individuals adapt to this design and can effectively use their natural vision.

In contrast, having both lenses correct distance vision or providing a single lens for near vision would not leverage the advantages of monovision. A uniform add power throughout the lens does not align with the individualized corrections for each eye either, as monovision aims to split the function rather than provide a blended correction. Thus, the specific combination of distance correction in one eye and near correction in the other is what defines the effectiveness and function of monovision design lenses.
